    Intended Use

    Acteon Imaging Suite software program is indicated for general dental and maxillofacial diagnostic imaging. It controls exam retrieval, display, enhancement, and saving of digital images from various digital imaging systems. It stores and communicates these images within the system or across computer systems at distributed locations.

    Device Description

    AIS-Acteon Imaging Suite is an application software suite providing a set of tools used to meet the imaging requirements set by different types of dental facilities – from small clinics to large hospitals. It enables practitioners to process and permanently archive (in connection with patients) diagnostic images relating to intraoral, maxillofacial and ear nose throat areas. Images can be originated by: intraoral digital sensors, dental panoramic and cephalometric equipment, CBCT equipment, intraoral cameras and all the future ACTEON digital imaging devices. The devices that are intended to be used with AIS are X-MIND trium, X-MIND PRIME and Cameras, Sopix², Sopix2 ACE, PSPix, PSPix2, SOPROCare camera and SOPROLife (with SDK provided by ACTEON-SOPRO). AIS supports DICOM format, which makes the system flexible and ready to be connected to other compatible devices and applications.

    AI/ML Overview

    The information provided does not contain a discrete table of acceptance criteria or reported device performance metrics in the format requested. However, it does outline a clinical suitability assessment that served as the performance testing for the device. Here's a summary based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The submission does not explicitly list quantitative acceptance criteria in a table format with corresponding reported device performance. Instead, it states that the device's clinical effectiveness was assessed by comparing its image rendering to that of predicate devices. The acceptance was qualitative: "image quality (anatomical coverage, density and image contrast and anatomical structures) to assess suitability for clinical use." The implied acceptance criterion was that the image rendering of the Acteon Imaging Suite should be comparable and clinically suitable to the predicate devices. The reported device performance is that this comparison led to the conclusion of "substantial equivalence" based on "bench tests that compare clinical suitability of the rendering performed by Acteon Imaging Suite with the predicates."

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

    The document mentions "the same images" were evaluated, but it does not specify the sample size (number of images or cases) used for the test set.
    The data provenance is not explicitly stated as retrospective or prospective, nor is the country of origin of the data mentioned.

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

    • Number of Experts: Three independent reviewers.
    • Qualifications: "having different backgrounds (maxillofacial surgery, orthodontics, dentistry)." No specific years of experience are provided.

    4. Adjudication Method

    The adjudication method appears to be consensus-based among the three independent reviewers judging "the image quality (anatomical coverage, density and image contrast and anatomical structures) to assess suitability for clinical use." No specific 2+1 or 3+1 method is described, but the phrase "Three independent reviewers... evaluated" implies a collective assessment rather than individual decisions.

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

    A multi-reader multi-case (MRMC) comparative effectiveness study was not explicitly stated as such. The study described was a qualitative comparison of image rendering for clinical suitability, where human readers (the three experts) compared the proposed device's output against predicate devices. The document does not report an effect size of how much human readers improve with AI vs without AI assistance because the device is an imaging suite, not an AI-powered diagnostic tool, and the study focused on image quality comparison, not diagnostic accuracy improvement.

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

    The device, "Acteon Imaging Suite," is an application software suite for general dental and maxillofacial diagnostic imaging, controlling image retrieval, display, enhancement, and saving. It is not an AI algorithm with standalone diagnostic capabilities. Therefore, a standalone performance study in the context of an "algorithm only without human-in-the-loop performance" was not conducted as the device's function is to facilitate human interpretation and management of images. The performance testing described relates to the quality of the image rendering by the software, which is then interpreted by humans.

    7. Type of Ground Truth Used

    The "ground truth" for the test set was effectively expert consensus regarding the clinical suitability of the rendered images. It was not pathology, outcomes data, or another objective measure, but rather the subjective expert evaluation of image quality for diagnostic purposes.

    8. Sample Size for the Training Set

    The document does not mention a training set sample size. The evaluation described is a performance comparison of the final product with predicate devices, not the training of a machine learning model.

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

    As no training set is mentioned in the provided text, there is no information on how ground truth for a training set was established.

    AI/ML Overview

    The provided text is a 510(k) summary for the X-MIND trium device, which is a digital panoramic, cephalometric, and tomographic extra-oral X-ray system. The document compares the proposed device to a predicate device, the Hyperion X9, to establish substantial equivalence.

    Here's an analysis of the acceptance criteria and the study that proves the device meets them:

    1. A table of acceptance criteria and the reported device performance:

    The document implicitly uses the performance of the predicate device, Hyperion X9, as the acceptance criteria for substantial equivalence, particularly for image quality and radiation dose, while also assessing compliance with relevant safety standards. The table below summarizes the key performance comparisons presented as part of the substantial equivalence claim. Since specific numerical acceptance criteria (e.g., "must meet X value") are not explicitly stated as distinct criteria but rather as comparison outcomes, this table presents the comparative performance as reported.

    CharacteristicAcceptance Criteria (Predicate Device - Hyperion X9)Reported Device Performance (X-MIND trium)Outcome
    Cephalometric Image QualityTest pattern images of certain qualityTest pattern images of equivalent qualitySubstantial equivalence confirmed by metrics

    Panoramic Image QualityTest pattern images of certain qualityTest pattern images of equivalent qualitySubstantial equivalence confirmed by metrics
    Panoramic Radiation DoseUnder DRL for Dental panoramic (100 mGycm²) according to NCRP Report No. 172 (2016)Under DRL for Dental panoramic (100 mGycm²) according to NCRP Report No. 172 (2016)Both Hyperion and X-MIND trium are under the DRL
    CBCT Image Quality (Standard Quality Protocols)Homogeneity: baseline as Hyperion X9Homogeneity: 2.8-10.9 times lower than Hyperion X9Homogeneity for Hyperion is 2.8-10.9 times higher than X-MIND trium
    CNR: baseline as Hyperion X9CNR: 2.12 ÷ 2.37 times higher than Hyperion X9CNR for Trium is 2.12 ÷ 2.37 times higher than the CNR for Hyperion
    MTF: baseline as Hyperion X9MTF plots show Trium better maintains high frequencies between 1.25 lp/mm and 1.5 lp/mmTrium better maintains high frequencies
    Nyquist frequency: baseline as Hyperion X9EquivalentEquivalent
    Absence of artifacts: baseline as Hyperion X9EquivalentEquivalent
    CBCT Radiation Dose (Standard Quality Protocols)Similar to Hyperion X9, within reasonable variationLower than Hyperion X9, but X-MIND trium dose can be reduced by using other scan protocols (implicitly aiming for equivalence or improvement)Hyperion is lower but the dose for X-MIND trium can be reduced by using other scan protocols (suggesting overall acceptable dose, though initially higher for some protocols if not adjusted)
    CBCT System Indicator ($S_{DAP}$)Substantial equivalence to Hyperion X9Calculated $S_{DAP}$ value (not explicitly reported but claimed to establish equivalence)Substantial equivalence is confirmed by $S_{DAP}$
    CBCT Image Quality (High Quality Protocols)Noise: baseline as Hyperion X9Voxel noise for Hyperion is 43.5% ÷ 53.8% higher than TriumVoxel noise for Hyperion is higher than Trium (implying Trium has lower noise)

    Electrical Safety & EMCCompliance with IEC 60601-1 3rd ed., IEC 60601-1-2: 2007, etc. (as per predicate)Compliance with same standards, plus US and Canada deviations (IEC 60601-1 deviations for US and Canada), IEC 60601-1: 2007, ANSI/AAMI ES60601-1: 2005, CAN/CSA C22.2 No. 60601-1:08, IEC 60601-1-3: 2008, IEC 60601-2-63: 2012, IEC 60601-1-6: 2010, IEC 62366: 2007Met and exceeded standards, with formal certifications from NRTLs.
    Software Verification & ValidationAs recommended by FDA GuidanceDocumentation provided as recommended by FDA Guidance for software in medical devicesSoftware considered "moderate" level of concern, V&V testing conducted. General tools and means made available by both software are equivalent.

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

    The document mentions that "bench tests" were performed for image quality and radiation dose. It refers to "test pattern images" and "clinical images obtained with X-MIND trium and predicate device." However, the sample size for the test set (number of images/cases) is not explicitly stated.

    The data provenance is likely retrospective, as the comparison involves existing images from the predicate device and newly generated images from the X-MIND trium under controlled bench test conditions. The country of origin of the data is not specified but given the manufacturer's location in Italy and the use of a Nationally Recognized Testing Laboratory (NRTL) (Intertek Semko, Nemko S.p.A.), it is likely that the testing was performed in Europe.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):

    The document does not mention the use of human experts to establish ground truth for the test set. The image quality assessments appear to be based on objective metrics derived from phantom studies (e.g., homogeneity, CNR, MTF, Nyquist frequency, artifacts, NPS), rather than subjective evaluations by clinical experts.

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

    Not applicable, as human expert evaluation for ground truth determination is not described. The assessment was based on objective metrics from bench tests.

    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 Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done. This device is an X-ray imaging system, not an AI-assisted diagnostic tool. The focus of the submission is on hardware and software equivalence for image acquisition and display, not on reader performance improvement with AI.

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

    Yes, standalone performance was done, but not in the context of an "algorithm" as typically conceived in AI/ML performance. The "device performance" described (image quality metrics, radiation dose, electrical safety, EMC) is the performance of the X-MIND trium system itself in a standalone capacity, i.e., without human intervention in the image generation part of the test. The "software" component also underwent verification and validation, but this refers to its functionality and reliability in image management and processing features available to the user, not an AI algorithm performing diagnostic tasks.

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

    The "ground truth" for the performance evaluation mostly relies on objective physical measurements and phantom studies. For image quality, metrics like homogeneity, CNR, MTF, Nyquist frequency, and NPS derived from test patterns or phantoms serve as the "truth" against which the device's imaging capabilities are measured. For radiation dose, established Dosimetry Reference Levels (DRLs) from NCRP REPORT No. 172 (2016) serve as the standard. For electrical safety and EMC, recognized international standards (e.g., IEC 60601 series) are the ground truth for compliance.

    8. The sample size for the training set:

    Not applicable. The device is an X-ray imaging system, not an AI/ML diagnostic algorithm that requires a training set of data.

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

    Not applicable. As stated above, this device does not involve a training set for an AI/ML algorithm.
