    Intended Use

    The Trinias is an angiographic X-ray system which is used for diagnostic imaging and interventional procedures. The Trinias is intended to be used for cardiac angiography, neurovascular angiography, abdominal angiography, peripheral angiography, rotational angiography, multi-purpose angiography and whole body radiographic/fluoroscopic procedures

    Device Description

    Trinias is an interventional fluoroscopic x-ray system which uses digital x-ray receptor panels for image acquisition. The system has been modified to include new image enhancement software feature called "SCORE Opera." This new feature applies AI (deep learning technology) filter technology to enable efficient noise suppression and contrast enhancement, and to improve the visibility of devices that are generally difficult to achieve under low dose conditions, catheters for example.

    AI/ML Overview

    The provided FDA 510(k) clearance letter and its associated summary for the "Trinias X-Ray System" (K252099) offer some details about the device's enhanced features and the studies conducted. However, it does not contain enough specific information to fully describe the acceptance criteria and the study that proves the device meets those criteria in the comprehensive manner requested.

    Specifically, the document states:

    • "The software was then subjected to non-clinical testing. Summary of non-clinical testing: We provided these detailed non-clinical test reports: The SCORE Opera Development process of leaning model AND a 2D Image Quality Evaluation Report."
    • "Clinical testing: A clinical image quality study was conducted. The objective of the study was to evaluate the clinical image quality of X-ray images processed by the Trinias system's AI algorithm. The study aims to confirm that the AI-enhanced images (AI-ON) maintain diagnostic quality compared to standard image processing (AI-OFF). This assessment is submitted to support the determination of substantial equivalence. The results confirm that the AI-ON processing frequently provides improved visibility of interventional devices and vessels."

    While these passages indicate that studies were performed, they lack crucial quantitative and qualitative details required to answer the specific questions below. The FDA 510(k) summary is generally an abbreviated public document; more detailed information would typically be found in the full 510(k) submission itself (which is not provided here).

    Therefore, I will extract and present what can be deduced from the provided text, and explicitly state when information is missing.


    Acceptance Criteria and Device Performance Study (K252099 - Trinias X-Ray System)

    1. Table of Acceptance Criteria and Reported Device Performance

    Criterion Description (Inferred from Study Objective)Acceptance Criteria (Not explicitly stated in the provided text, but inferred goal)Reported Device Performance (From "Clinical Image Quality Study")
    Clinical Image Quality: Diagnostic QualityAI-enhanced images (AI-ON) must maintain diagnostic quality compared to standard image processing (AI-OFF)."The results confirm that the AI-ON processing frequently provides improved visibility of interventional devices and vessels."
    Clinical Image Quality: Visibility of DevicesSpecific metric or threshold not stated. (Implied: Improve or at least not degrade visibility)"Frequently provides improved visibility of interventional devices and vessels."
    Noise Suppression & Contrast EnhancementSpecific metrics or thresholds not stated in document.AI (deep learning technology) filter applied "to enable efficient noise suppression and contrast enhancement."
    Safety and EffectivenessNot to present any new issues of safety and effectiveness compared to predicate."Does not present any new issues of safety and effectiveness." "Performs as well as or better than our predicate."

    Missing Information: The document does not provide specific, quantifiable acceptance criteria (e.g., "AI-ON images must achieve a minimum diagnostic rate of X%," or "visibility scores must improve by Y points on a Z-point scale"). The reported performance is qualitative and comparative.

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size for Test Set: Not specified. The document mentions "A clinical image quality study was conducted" but provides no details on the number of images or cases included in this study.
    • Data Provenance: Not specified. The country of origin of the data (e.g., images) used in the clinical study is not mentioned. It is unclear if the data was retrospective or prospective.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

    • Number of Experts: Not specified.
    • Qualifications of Experts: Not specified.

    4. Adjudication Method for the Test Set

    • Adjudication Method: Not specified. No information is given on how discrepancies among experts (if multiple were used) were resolved or how the final "ground truth" for diagnostic quality and visibility was established.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    • MRMC Study Done: Not explicitly stated as an MRMC study, but a "clinical image quality study" comparing AI-ON and AI-OFF was conducted. This type of study often involves human readers, which aligns with the spirit of an MRMC study, even if not formally named such. The document states, "The study aims to confirm that the AI-enhanced images (AI-ON) maintain diagnostic quality compared to standard image processing (AI-OFF)."
    • Effect Size of Human Readers' Improvement with AI vs. Without AI Assistance: Not quantified or reported. The document only qualitatively states that "the AI-ON processing frequently provides improved visibility of interventional devices and vessels." It does not provide any statistical effect size or direct measure of how much human readers improved their diagnostic performance or speed with AI assistance.

    6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

    • Standalone Study Done: Yes, implicitly. The AI algorithm's function is described as processing images ("AI (deep learning technology) filter technology to enable efficient noise suppression and contrast enhancement"). The "2D Image Quality Evaluation Report" mentioned under non-clinical testing likely includes standalone evaluations of the algorithm's output before human review, though specific metrics are not provided in this summary. The clinical study compared images from AI-ON vs. AI-OFF processing, implying these are the outputs of the standalone algorithm before human interpretation.

    7. Type of Ground Truth Used

    • Type of Ground Truth: Inferred to be expert consensus or expert interpretation. For a "clinical image quality study" aiming to assess "diagnostic quality" and "visibility of interventional devices and vessels," the ground truth would most typically be established by experienced clinicians (e.g., interventional radiologists/cardiologists) who review and rate the images. The document does not mention pathology, outcomes data, or other objective measures for ground truth.

    8. Sample Size for the Training Set

    • Sample Size for Training Set: Not specified. The document mentions "The SCORE Opera Development process of leaning model" (likely meaning "learning model"), indicating AI/deep learning training, but no details about the size or characteristics of the training data are provided.

    9. How the Ground Truth for the Training Set Was Established

    • How Ground Truth Was Established (Training Set): Not specified. For a deep learning model, the training set would require labeled data. The method for generating these labels (ground truth) is not described. This could involve manual annotation by experts, consensus, or other automated/semi-automated methods, but the document is silent on this point.

    In summary, while the K252099 document confirms that a clinical image quality study and non-clinical evaluations were performed to support the new "SCORE Opera" AI feature, it lacks specific quantitative acceptance criteria, sample sizes for test and training data, details on expert qualifications, and the formal methodologies for ground truth establishment and adjudication. The reported performance is qualitative, stating "improved visibility" and maintenance of "diagnostic quality."

The αEvolve imaging chain incorporates Artificial Intelligence Denoising (AID) for real-time fluoroscopic noise reduction, as well as Multi-Frequency Processing (MFP), a signal enhancement algorithm.

    AI/ML Overview

    The provided 510(k) clearance letter describes performance testing for an interventional fluoroscopic X-ray system called "Alphenix, INFX-8000V/B, INFX-8000V/S, V9.6 with αEvolve Imaging (FOV Extension)". This device includes "Artificial Intelligence Denoising (AID)" and a "Multi Frequency Processing (MFP)" signal enhancement algorithm. The testing compares the subject device's αEvolve Imaging chain with AID to the predicate device's "super noise reduction filter (SNRF)".

    Here's an analysis of the acceptance criteria and the study details:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria are generally defined as the subject device performing "equivalent to or better than" the predicate, or "significantly better" (p < 0.05), or showing "no unexpected distortions" and "maintained or improved" performance.

    Performance TestAcceptance CriteriaReported Device Performance
    Binning Mode Bench Test Results
    Change in Image Level, Noise Magnitude and SNRImage-level similarity using TOST, and noise magnitude and SNR properties equivalent to or better than the predicate (one-sided Student's t-test).Noise and SNR properties of the subject device were equivalent to or better than those of the predicate.
    Noise Power Spectrum (NPS)Absence of unexpected distortions (e.g., spikes).Both NPS curves were smooth and free of unexpected distortions. The subject IP chain exhibited a flatter NPS curve, with lower noise at spatial frequencies below ~0.6 cycles/mm and slightly higher noise above that range.
    Noise Texture via KurtosisSubject IP chain's kurtosis being significantly closer to 3 than the predicate (p < 0.05) in most test cases.The subject IP chain consistently met this criterion, indicating a more Gaussian-like noise distribution, while the predicate exhibited higher kurtosis.
    Modulation Transfer Function (MTF)MTF curve showed reduced over-enhancement and no unexpected distortions.Both MTF curves were smooth and free of unexpected distortions. The subject IP chain applied more moderate enhancement compared to the predicate's higher MTF peak.
    Noise Equivalent Quanta (NEQ)Subject IP chain demonstrating higher NEQ in the low to mid spatial frequency range compared to the predicate IP chain.The subject IP chain consistently outperformed the predicate in the 0–0.5 lp/mm range.
    Low Contrast Detectability (LCD)Subject IP chain performed significantly better than the predicate (p < 0.05), or no statistically significant difference in most test cases.Across all conditions, the subject IP chain consistently demonstrated lower percent contrast values than the predicate (superior LCD performance), with improvements statistically significant in all cases (p < 0.05).
    Contrast-to-Noise Ratio (CNR) of High Contrast ObjectSubject IP chain performed significantly better than the predicate (p < 0.05), or no statistically significant difference in most test cases.The subject IP chain significantly outperformed the predicate in all cases (p < 0.05), indicating a consistent and statistically significant improvement in CNR.
    Hi-Def Mode Bench Test Results
    Change in Image Level, Noise Magnitude and SNRImage-level similarity using TOST, and noise magnitude and SNR properties equivalent to or better than the predicate (one-sided Student's t-test).Noise and SNR properties of the subject device were better than those of the predicate.
    Noise Power Spectrum (NPS)Absence of unexpected distortions (e.g., spikes) and a reduction in noise at high spatial frequencies.Both NPS curves were smooth and free of unexpected distortions. The subject IP chain exhibited lower noise at spatial frequencies at mid and high frequencies above 2 cycles/mm.
    Noise Texture via KurtosisSubject IP chain's kurtosis being significantly closer to 3 than the predicate (p < 0.05) in most test cases.The subject IP chain consistently met this criterion, indicating a more Gaussian-like noise texture and statistically lower kurtosis than the predicate.
    Modulation Transfer Function (MTF)Maintained or improved NEQ in the higher spatial frequency range (referencing Test 5).Both MTF curves were smooth and free of unexpected distortions, and the subject IP chain demonstrated lower spatial resolution than the predicate chain (this needs to be read in conjunction with the NEQ results for success criteria).
    Noise Equivalent Quanta (NEQ)Subject IP chain exhibiting higher NEQ in the mid to high spatial frequency range compared with the predicate IP chain.Results demonstrated that the subject IP chain consistently outperformed the predicate in mid and high frequencies.
    Low Contrast Detectability (LCD)Subject IP chain performed significantly better than the predicate (p < 0.05).The results were considered acceptable, as the subject IP chain outperformed the predicate in the majority of ROI sizes (3 out of 4).
    Contrast-to-Noise Ratio (CNR) of High Contrast ObjectSubject IP chain performed significantly better than the predicate (p < 0.05) in most test cases.Results showed that the subject IP chain significantly outperformed the predicate in all cases, indicating a consistent and statistically significant improvement in CNR.

    2. Sample size used for the test set and the data provenance

    The document does not specify exact sample sizes for the test sets in terms of number of patients or images. The tests primarily utilized:

    • Phantom data: Anthropomorphic chest phantoms and PMMA slab phantoms.
    • Clinical datasets: Mentioned in image quality evaluations, but no further details provided regarding number or source.
    • Data provenance: Not explicitly stated (e.g., country of origin, retrospective/prospective). The use of phantoms is a controlled laboratory setting.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    Not applicable. The reported tests are primarily quantitative bench tests using phantoms or objective image quality metrics, not dependent on expert interpretation for ground truth.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    Not applicable, as the tests involve quantitative metrics measured from phantoms or images, rather than human expert adjudication.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    No MRMC comparative effectiveness study involving human readers is mentioned in the provided text. The testing focuses on objective image quality metrics using phantoms and clinical datasets.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    Yes, the described performance testing is a standalone assessment of the αEvolve Imaging chain, including the Artificial Intelligence Denoising (AID) algorithm, without a human-in-the-loop component. The "reported device performance" directly reflects the algorithm's impact on image quality parameters.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    The ground truth for most tests is derived from:

    • Physical phantoms: Anthropomorphic chest phantoms and PMMA slab phantoms, which provide known geometries and material properties for objective measurement.
    • Defined physical metrics: Metrics like image level, noise magnitude, SNR, NPS, kurtosis, MTF, NEQ, LCD, and CNR are calculated based on the image data and the known characteristics of the phantoms. There is no "ground truth" established by clinical experts or pathology in these technical bench tests.

    8. The sample size for the training set

    The document does not provide any information regarding the training set size for the Artificial Intelligence Denoising (AID) algorithm.

    9. How the ground truth for the training set was established

    The document does not provide any information on how the ground truth for the AID algorithm's training set was established.

    Intended Use

    The Cara System is intended for preplanning and guidance of medical interventions in an area known to contain or be adjacent to the cardiac conduction system, such as percutaneous or surgical procedures, for example, transcatheter aortic valve replacement (TAVR), as well as medical procedures where the physician desires to deliver therapy to the patient's cardiac conduction system or to a targeted location within it (CSP).

    The Cara System uses computed tomography angiography (CTA)-based and user manually marked landmarks to identify the cardiac conduction axis and generate a three-dimensional (3D) map of the individual patient's cardiac conduction system. The system also overlays the anatomical location of the cardiac conduction system (generated by the Cara Metis Simulator using pre-procedure CT data) onto live fluoroscopic images.

    The software utilizes AI/ML algorithms to provide OCR detection, automated segmentation of anatomical structures, and detection of catheters.

    The CARA System is intended for use in adult patients (18 years of age and older).

    Device Description

    The CARA System is a medical device comprising two integrated functions. The CARA System device components include the CARA Metis Simulator and the CARA Atlas Navigator. Both components provide diagnostic imaging software and hardware functions that identify the personalized anatomical location of the cardiac conduction system in relation to other heart anatomies based on a patient's computed tomographic angiography (CTA). The former is intended for preplanning (1) a medical intervention in an area known to contain or be adjacent to the cardiac conduction system or (2) a medical procedure(s) where the physician desires to deliver therapy to the patient's cardiac conduction system. The latter identifies the personalized anatomical location of the cardiac conduction system overlaid on real-time, intra-procedural, fluoroscopic imaging and provides guidance during interventional structural heart disease procedures in an area known to contain or be adjacent to the cardiac conduction system or where the physician desires to deliver therapy to the patient's cardiac conduction system.

    The CARA Metis Simulator uses computed tomography angiography (CTA)-based landmarks to accurately identify the cardiac conduction axis and run a simulation generating the personalized three-dimensional (3D) map of the individual patient's cardiac conduction system.

    This 3D map is then utilized by the clinical operator to plan any procedure to either target, as in direct pacing, or avoid as in structural heart disease interventions, the cardiac conduction system. As described below, this technology is based on methodical translational studies investigating the 3D location of the cardiac conduction system relative to cardiac structures visible by clinical imaging with initial assessment and validation in the clinical setting.

    The CARA Atlas Navigator is designed to overlay the personalized anatomical location of the cardiac conduction system (generated by the Cara Metis Simulator using pre-procedure CT data) onto live fluoroscopic images. This functionality assists clinicians during fluoroscopy-guided interventional heart procedures.

    The Cara Atlas Navigator consists of both software and hardware components:

    1. Fluoroscopy Splitter (F-Splitter) – This device splits the live fluoroscopy image for integration with the CARA System.

    2. CARA Box – A standard workstation that receives live fluoroscopy images from the Fluoroscopy Splitter and enhances them by adding anatomical landmarks. The CARA Box acts as the system's central processing unit, handling data analysis and image processing. It is equipped with user interface devices, such as a mouse and keyboard.

    3. CARA Monitor – Displays the enhanced fluoroscopy images, including the analysis performed by the CARA Box. This monitor is typically located in the control room. The same output is also projected onto the main display in the operating room.

    The CARA System utilizes a specific on-premises workflow to ensure data integrity and clinical accuracy. Prior to physician use, a certified CARA Clinical Expert (CCE) must be physically present on-site. The CCE logs into the CARA Box workstation to prepare the CARA Metis pre-planning process. This includes initiating the automated segmentation, verifying the anatomical output, annotating landmarks, and saving the results to the local storage.

    The physician subsequently logs into the same workstation using distinct credentials to load, review, and confirm the pre-planned case. This workflow ensures that all generated outputs are professionally prepared and verified before clinical review.

    The CARA System utilizes AI/ML algorithms to provide OCR (Optical Character Recognition), automated segmentations and device tracking:

    • OCR detection - is used to automatically extract metadata from the live feed of the fluoroscopy machine (e.g., c-arm position, focal distance, etc.).
    • Segmentations - the system utilizes deep learning models to automatically generate anatomical segmentations of the heart chambers and aorta.
    • Device Detection - using a segmentation model the system detects the distal tips of specific interventional devices (e.g., Pigtail catheters, CS catheters, pacing leads) within the fluoroscopic image to support real-time tracking and present overlay.

    AI-based segmentations are provided to assist the workflow but may contain inaccuracies. The AI output should not be used as the sole basis for clinical decision-making. Clinical oversight is mandatory.

    Here's a breakdown of the acceptance criteria and study details for the CARA System, based on the provided FDA 510(k) clearance letter:

    The adjudication method clearly states "adjudicated by a U.S. Board-Certified Interventional Cardiologist." This implies a single expert review of the preliminary ground truth established by trained technologists/manual annotators. It does not indicate a 2+1 or 3+1 consensus method.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No MRMC comparative effectiveness study was mentioned in the provided document. The study described focuses on the device's standalone performance and a retrospective clinical correlation, not on comparing human reader performance with and without AI assistance.

    6. Standalone Performance Study

    Yes, a standalone (algorithm only without human-in-the-loop performance) study was done for the AI/ML algorithms. The "AI/ML Performance Summary" table directly details the performance of the OCR, anatomical segmentation, and catheter/lead detection algorithms on independent test datasets, measured against ground truth.

    7. Type of Ground Truth Used

    • AI/ML Algorithms: Expert consensus (adjudication by a U.S. Board-Certified Interventional Cardiologist) applied to initial manual annotations by trained technologists for anatomical segmentations and catheter/lead detection. Manual verification for OCR.
    • Clinical Performance Data: Retrospective clinical outcomes data (Permanent Pacemaker Implantation rates, Left Ventricular Ejection Fraction improvement) associated with the CARA-visualized Conduction System Axis and Left Bundle Branch Pacing.

    8. Sample Size for the Training Set

    The document states, "Algorithms were trained using retrospective, multi-site clinical datasets," but does not specify the sample size used for the training set. It only mentions that "Training and test datasets were independent."

    9. How the Ground Truth for the Training Set was Established

    The document states, "Algorithms were trained using retrospective, multi-site clinical datasets." While it describes how ground truth was established for the validation/test set (manual segmentation by trained technologists with physician adjudication), it does not explicitly detail how the ground truth for the training set was established. It is implied that similar methods would have been used, but it's not directly stated.
