    Intended Use

    OSCAR 15 & OSCAR 15i are a mobile fluoroscopy system designed to provide fluoroscopic and spot film images of the patient during diagnostic, surgical and interventional procedures. Examples of clinical application may include cholangiography, endoscopy, urologic, neurologic, vascular, cardiac and critical care. The system may be used for other imaging applications at the physician's discretion. OSCAR 15i are indicated only for adult patients.

    Device Description

    The OSCAR 15 & OSCAR 15i, C-Arm Mobile are used for providing fluoroscopic and radiographic images of patient anatomy, especially during special procedures in a hospital or medical clinics. The fluoroscopic mode of operation is very useful to the attending physician to see the images on real time without the need to develop individual films. These devices are intended to visualize anatomical structures by converting a pattern of x-radiation into a visible image through electronic amplification. The OSCAR 15 & OSCAR 15i consist of the X-ray tube assembly, X-ray controller, Image receptor and some accessories with no wireless function. The difference between OSCAR 15 and OSCAR 15i is only image acquisition parts. (An Flat Panel Detector (FPD) is applied to OSCAR 15, and an Image instensifier is applied to OSCAR 15i.)

    AI/ML Overview

    The provided text is a 510(k) Pre-Market Notification for the OSCAR 15 & OSCAR 15i mobile fluoroscopy systems. It asserts substantial equivalence to a predicate device (OSCAR 15, K172180) and describes non-clinical performance and safety testing. However, it does not include specific acceptance criteria or a study that directly quantifies device performance against those criteria in a format applicable to AI/CADe devices (e.g., sensitivity, specificity, FROC analysis).

    The document is concerned with demonstrating that the devices (OSCAR 15 and the newly added OSCAR 15i) function safely and effectively as fluoroscopic X-ray systems, primarily through comparison to a previously cleared predicate device and compliance with relevant IEC and CFR standards. It describes physical and technical specifications and differences, particularly in the image acquisition parts (Flat Panel Detector vs. Image Intensifier).

    Therefore, based on the provided text, I cannot complete the requested tables and information for acceptance criteria and a study proving the device meets those criteria in the way typically expected for AI/CADe devices, as this information is not present. The document focuses on regulatory compliance and substantial equivalence for an imaging hardware device, not an AI/CADe algorithm.

    Here's what can be extracted and what is missing based on your request:


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

    • Acceptance Criteria: Not explicitly stated in terms of specific performance metrics (like sensitivity, specificity, accuracy) that would be common for AI/CADe devices. The acceptance criteria for this type of device are primarily compliance with safety and performance standards (e.g., IEC 60601 series, 21 CFR 1020.30, 1020.31, 1020.32) and demonstrating "substantial equivalence" to a predicate device.
    • Reported Device Performance: The document states that "the performance related to image quality was also different" due to the detector change, and "The image performance was evaluated according to the IEC standard through performance bench testing demonstrated that these differences do not matter and effectiveness in comparison with the predicate device." It also mentions "clinical images have been evaluated by a licensed radiologist confirmed the sufficient diagnostic quality to provide accurate information." However, no quantified performance metrics are provided.

    2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Test Set Sample Size: Not specified. The document mentions "performance bench testing" and evaluation of "clinical images" but does not give a number for images or cases used in these evaluations.
    • Data Provenance: Not specified.

    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)

    • Number of Experts: One ("a licensed radiologist") is mentioned for evaluating clinical images.
    • Qualifications of Experts: Only "a licensed radiologist" is mentioned; no specific experience level or sub-specialty is provided.

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

    • Adjudication Method: Not specified. Only one radiologist is mentioned for evaluation, implying no consensus/adjudication process was detailed.

    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

    • MRMC Study: No, an MRMC study targeting human reader improvement with AI assistance was not mentioned. The device is a fluoroscopy system, not an AI/CADe tool for interpreting images.

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

    • Standalone Performance: No, this does not apply. The device is a fluoroscopy system, a hardware imaging device, not an algorithm being evaluated in a standalone capacity.

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

    • Type of Ground Truth: For the "clinical images," the "sufficient diagnostic quality" was confirmed by a "licensed radiologist." This implies a form of expert opinion/judgment, but it's not explicitly framed as establishing a ground truth for a diagnostic algorithm. For the hardware performance, ground truth would be adherence to physical and electrical specifications verified through bench testing.

    8. The sample size for the training set

    • Training Set Sample Size: Not applicable/not mentioned. This device is a hardware fluoroscopy system, not an AI model requiring a training set.

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

    • Ground Truth for Training Set: Not applicable/not mentioned, as there is no AI model or training set described.

    Device Description

    The Insight Enhanced™ DRF Digital Imaging System is designed to provide an additional imaging acquisition device to the existing image intensifier, camera and user interface with a dynamic flat-panel detector (dFPD) on the following FDA approved R&F fluoroscopic imaging systems employing an image intensifier: GE Advantx, GE Legacy, GE P500 and Shimadzu YSF300. The subject fluoro system Insight Enhanced is based on the predicate Insight Essentials. The following dynamic digital detectors are added to the predicate system: Vivix-D 1212G and Vivix-D 1717G. The x-ray generator, beam-limiting device and patient positioner, necessary for a full fluoroscopy system are not part of the subject device software stays unchanged from the predicate Insight Essentials DRF.

    The Insight Enhanced™ DRF Digital Imaging System allows the operator to view and enhance high-definition fluoroscopy images. High resolution digital spot images may also be acquired at single or rapid acquisition rates, up to 30 fps. Images may be viewed and enhanced enabling the operator to bring out diagnostic details difficult or impossible to see using conventional imaging techniques. Images can be stored locally for short term storage. The Insight Enhanced™ DRF Digital Imaging System enables the operator to produce hardcopy images with a laser printer or send images over a network for longer-term storage. The major system components include: a fluoroscopic video camera, monitors, and an image processor PC.

    AI/ML Overview

    The provided text is a 510(k) summary for the Insight Enhanced™ DRF Digital Imaging System. It describes a device that adds dynamic flat-panel detectors (dFPD) to an existing, already cleared fluoroscopic imaging system. The submission argues for substantial equivalence to a predicate device, the Insight Essentials™ DRF Digital Imaging System (K191310).

    Based on the provided text, the device does not have acceptance criteria related to its performance in terms of diagnostic effectiveness that would be proven by a clinical study. Instead, the "acceptance criteria" here relate to demonstrating substantial equivalence to a predicate device, primarily through non-clinical bench testing.

    Here's a breakdown of the information requested, based on the provided document:


    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (for Substantial Equivalence to Predicate)Reported Device Performance (Summary of Non-Clinical Tests)
    Intended Use: Identical to predicate device.The Insight Enhanced™ DRF Digital Imaging System has the SAME intended use as the predicate device.
    Power Source: Identical to predicate device.The Insight Enhanced™ DRF Digital Imaging System has the SAME power source (120 VAC 50/60 HZ, 2.5 amps) as the predicate.
    Image Acquisition: Comparable to predicate device (up to 15 FPS spot, up to 30 fps fluoro).The Insight Enhanced™ DRF Digital Imaging System has SAME image acquisition rates (up to 15 FPS spot, up to 30 fps fluoro) as the predicate.
    File Compatibility: Identical to predicate device (DICOM).The Insight Enhanced™ DRF Digital Imaging System has the SAME file compatibility (DICOM) as the predicate.
    Digital Resolution: Comparable to predicate device (1k x 1k 12 bit).The Insight Enhanced™ DRF Digital Imaging System has the SAME digital resolution (1k x 1k 12 bit) as the predicate (even though the digital video source has changed).
    Electrical Safety: Conforms to same standards as predicate.The Insight Enhanced™ DRF Digital Imaging System conforms to the SAME electrical safety standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3) as the predicate.
    Technological Characteristics: Differences (dFPDs) do not raise new questions of safety or effectiveness.Bench testing was performed using phantom images acquired with the subject device and compared to the predicate device on the same GE Legacy R&F system. The images and doses were analyzed and compared, demonstrating substantial equivalence. The dFPDs are from the same company (Vieworks) and use similar technology. One dFPD (VIVIX-D1212) was previously cleared (K180473).
    Risk Management: Risks analyzed with FMEA; mitigated and accepted.The device was developed to provide optimized workflow and meet functional requirements and international safety standards. Risk analysis (FMEA) concluded all identified risks were successfully mitigated.

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

    • Sample Size for Test Set: Not explicitly stated in terms of patient images. The "test set" described consists of phantom images. The document mentions that "Phantom images were acquired with the subject device and compared to the predicate device, also installed on the same GE Legacy R&F system." The number of phantom images acquired or the specifics of the phantom used are not provided.
    • Data Provenance: The data is from non-clinical bench testing rather than human subjects. No country of origin is specified for these bench tests, but they were conducted to support a U.S. FDA submission.

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

    • This information is not applicable as the test involved non-clinical bench testing with phantoms and direct comparison to a predicate device, not diagnostic performance with human readers against a human-established ground truth.

    4. Adjudication Method for the Test Set

    • This information is not applicable as the test involved non-clinical bench testing with phantoms. The comparison was based on analysis of the acquired phantom images and doses, not expert adjudication of diagnostic outcomes.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

    • No, an MRMC comparative effectiveness study was not done. The submission explicitly states: "No clinical data is necessary to evaluate safety or effectiveness for purposes of determining substantial equivalence of the proposed modification. Bench testing was performed to assess the device safety and effectiveness."

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study Was Done

    • The device described is an imaging system component (dynamic flat-panel detectors added to a fluoroscopic imaging system), not an AI algorithm. Its performance is evaluated as part of the overall imaging system's ability to acquire images comparable to a predicate device. Therefore, the concept of a "standalone algorithm" performance study is not applicable in the context of this submission. The "algorithm" if any, is likely for image processing, which is stated to be "unchanged from the predicate Insight Essentials DRF."

    7. The Type of Ground Truth Used

    • For the non-clinical bench testing, the "ground truth" was effectively the performance of the legally marketed predicate device (Insight Essentials™ DRF Digital Imaging System) and its ability to produce comparable phantom images and use similar doses.

    8. The Sample Size for the Training Set

    • This information is not applicable. The device is an imaging system component, not an AI model that requires a training set. The software for image processing and workflow functions is stated to be "unchanged from the predicate Insight Essentials DRF."

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

    • This information is not applicable as there is no mention of an AI model with a training set.
