    AI/ML Overview

    The provided document is a 510(k) summary for the "Viewer" device from Brainlab AG. It describes the device, its intended use, and its comparison to a predicate device and a reference device to demonstrate substantial equivalence. However, it does not contain the detailed information required to fill out the table of acceptance criteria and the study that proves the device meets those criteria, specifically regarding device performance metrics (e.g., sensitivity, specificity, accuracy), sample sizes, ground truth establishment, or multi-reader multi-case studies for AI components.

    The document primarily focuses on verifying the software's functionality, user interface, DICOM compatibility, and integration, rather than clinical performance metrics of an AI algorithm. The device is a "Picture Archiving And Communications System" (PACS) that displays medical images and other healthcare data and is not intended for primary image diagnosis. This indicates that the regulatory requirements for performance metrics such as sensitivity and specificity, which are common for AI algorithms involved in diagnosis, would not apply to this specific device.

    Therefore, most of the information requested in your prompt cannot be extracted from this document because the device described is not an AI diagnostic algorithm, and the provided text focuses on software functionality verification rather than clinical performance studies.

    Here's what can be extracted and what cannot:

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

    Acceptance Criteria CategoryTest Method SummaryReported Device Performance
    User interfaceInteractive testing of user interfaceAll tests passed
    DICOM compatibilityInteractive testing with companywide test data, which are identical for consecutive version of the SWAll tests passed
    ViewsInteractive testing of user interfaceAll tests passed
    Unit test /Automatic testsAutomated or semi-automated cucumber tests or unit tests are written on the applicable level for new functionalities of the Viewer in respect to previous versions. Existing tests have to pass.All tests passed
    Integration testInteractive testing on various platforms and combination with other products following test protocols, combined with explorative testing. The software is developed with daily builds, which are explanatively tested.All tests passed
    UsabilityUsability tests (ensure user interface can be used safely and effectively)All tests passed
    Communication & CybersecurityVerification of communication and cybersecurity between Viewer and Magic Leap Mixed Reality glassesSuccessfully passed

    Missing Information/Not Applicable: The document does not provide acceptance criteria or performance metrics related to diagnostic accuracy (e.g., sensitivity, specificity, AUC) because the device is explicitly stated as not intended for primary image diagnosis.

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

    • Sample Size for Test Set: Not specified. The verification tests mention "companywide test data" and "various platforms and combination with other products" but do not provide specific numbers of cases or images.
    • Data Provenance: Not specified. The document mentions "companywide test data" but does not detail the country of origin or whether it was retrospective or prospective.

    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)

    • Not applicable/Not specified. Since the device is not for primary diagnosis and the tests focus on software functionality, there is no mention of experts establishing ground truth for diagnostic purposes. The "ground truth" for the software functionality tests would be the expected behavior of the software.

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

    • Not specified. The testing methods described are interactive testing, automated/semi-automated tests, and usability tests. There is no mention of an adjudication method typical for diagnostic performance studies.

    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

    • Not applicable. The document does not describe an AI algorithm intended to assist human readers in diagnosis. It's a DICOM viewer. Therefore, an MRMC study comparing human readers with and without AI assistance was not performed or reported.

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

    • Not applicable. This device is a viewer, not a standalone diagnostic algorithm.

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

    • The concept of "ground truth" in the context of diagnostic accuracy (e.g., pathology, expert consensus) does not apply here as the device is not for primary diagnosis. For its stated functions, the "ground truth" would be the expected, correct functioning of the software features (e.g., correct display of DICOM data, accurate measurements of distance/angle).

    8. The sample size for the training set

    • Not applicable/Not specified. The device is a viewer, not an AI model that undergoes a "training" phase with a dataset.

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

    • Not applicable. (See point 8).

    Intended Use

    The Image Fusion Element is an application for the co-registration of image data within medical procedures by using rigid and deformable registration methods. It is intended to align anatomical structures between data sets.

    The Image Fusion Element can be used in clinical workflows that benefit from the co-registration of image data. For example, this applies to navigation systems or medical data information terminals for image processing or image guided surgery in general as well as for treatment planning software for radiosurgery and radiotherapy. The device itself does not have specific clinical indications.

    Device Description

    The Image Fusion Element is intended to co-register volumetric medical image data (e.g. MR, CT). It allows rigid image registration to adjust different spatial position and orientation of two data sets. It also offers deformable registration to compensate image distortion or spatial deviation between image acquisitions.

    The Image Fusion Element gives the possibility to show basic planning content (e.g. objects, points, trajectories) defined from one dataset on another dataset and to display datasets of corresponding anatomic planes simultaneously. Further it could process co-registered data to highlight differences between distinct scanning sequences or to assess the response to a treatment.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for Brainlab AG's "Image Fusion" device. It outlines the device's intended use, technological characteristics, and a summary of safety and effectiveness, primarily through demonstrating substantial equivalence to predicate devices.

    However, this document does not contain the detailed study information typically found in a clinical performance study report that would prove the device meets specific acceptance criteria using a test set, ground truth, and statistical analysis as requested in your prompt. The document outlines a verification and validation (V&V) process, but it does not specify quantitative acceptance criteria or report the results of a controlled study against a predefined ground truth in the manner you've described.

    Instead, the document focuses on:

    • Substantial Equivalence: Comparing the device's features and functionality to existing legally marketed predicate devices (Mirada XD, K101228, and iPlan, K113732). The "Changes to Predicate Device" section and the "Technological Characteristics" table highlight this comparison.
    • Verification and Validation Summary: Stating that verification and validation were performed according to internal plans and processes, including usability testing, to ensure design specifications are met and the device can be used safely. There are no specific performance metrics or statistical results presented.

    Therefore, I cannot provide the information requested in your numbered list for this specific device from the provided text, as the necessary details regarding acceptance criteria, study design, sample sizes, ground truth establishment, or expert involvement for a clinical performance study are not present.

    The document's statement: "Functionality and features considered as substantially equivalent have been verified and validated. The system Image Fusion with its set of functionalities is substantially equivalent to its predicate devices," serves as the core of its argument for market clearance rather than presenting a detailed clinical study demonstrating quantitative performance against specific acceptance criteria.

    Intended Use

    The Elements Diagnostic Unit is intended to be used in dentistry to test the vitality of a tooth and to locate the apical foramen of a root canal in conjunction with endodontic root canal treatment.

    Device Description

    The device is a battery-operated, endodontic diagnostic unit designed to be used in either of two modes, V as a pulp tester to test the vitality of a tooth (by passing a pulsed, low-current, varying-voltage signal through the tooth), or A as an apex locate the apical foramen of a root canal (by measuring the impedance within a root canal) during root canal treatment. The unit uses a rechargeable battery pack, and can be used while the pack is charging. A remote satellite display that mirrors the values on the unit's graphic display can be attached to a chair, patient's bib or microscope for a more ergonomic monitoring of diagnostic status. To improve visibility and decrease eyestrain, the main body of the unit can be rotated from a vertical orientation to a 30° angle. The automatic power-off feature saves battery life and assures that the device is not left on inadvertently. The endodontic diagnostic unit is controlled by a microprocessor that is designed to support a network style communication allowing information to be shared between endodontic devices. The remote satellite display and cord assembly are completely removable. The probes, lip clips and file clips used with the device are autoclavable.
