Device Description

BriefCase is a radiological computer-assisted triage and notification software device. The software system is based on an algorithm programmed component and is comprised of a standard off-theshelf operating system, the Microsoft Windows server 2012 64bit, and additional applications, which include PostgreSQL. DICOM module and the BriefCase Image Processing Application. The device consists of the following three modules: (1) Aidoc Hospital Server (AHS); (2) Aidoc Cloud Server (ACS); and (3) Aidoc Worklist Application that is installed on the user's desktop and provides the user interface in which notifications from the BriefCase software are received.

DICOM images are received, saved, filtered and de-identified before processing. Series are processed chronologically by running an algorithm on each series to detect suspected findings and then notifications on flagged series are sent to the Worklist desktop application, thereby prompting preemptive triage and prioritization.

The Worklist Application displays the pop-up text notifications of new studies with suspected findings when they come in. Notifications are in the form of a small pop-up containing patient name, accession number and the relevant pathology (e.g., CSF). A list of all incoming cases with suspected findings is also displayed. Hovering over a notification or a case in the worklist pops up a compressed, small black and white, unmarked image that is captioned "not for diagnostic use" and is displayed as a preview function. This compressed preview is meant for informational purposes only, does not contain any marking of the findings, and is not intended for primary diagnosis beyond notification.

Presenting the user with notification facilitates earlier triage by prompting the user to assess the relevant original images in the PACS. Thus, the suspect case receives attention earlier than would have been the case in the standard of care practice alone.

AI/ML Overview

The provided document focuses on the Aidoc Medical, Ltd.'s BriefCase (K203508) device. It discusses the device's indications for use and demonstrates its substantial equivalence to several predicate devices. The key aspect of this submission is the broadening of the intended user population from "radiologists" to "appropriately trained medical specialists".

Crucially, the document explicitly states multiple times (on pages 11, 15, 19, 23, 27, and 32) that "Performance data was not needed to support this modification to BriefCase." This means that a new study was not conducted to demonstrate that the device meets separate acceptance criteria for K203508. Instead, the current submission relies on the performance data of the predicate devices (K190896, K180647, K190072, K193298, K201020, K192383).

Therefore, I cannot provide a table of acceptance criteria and reported device performance for K203508, nor information about a specific study proving it meets these criteria, as such a study was not performed for this specific submission according to the document. The document's argument for substantial equivalence is based on the identical intended use, technological characteristics, and principles of operation, with the only change being the expanded user population, which the FDA agrees does not raise new questions of safety or effectiveness.

However, I can extract the information related to the performance data that was used to support the initial clearance of the predicate devices, as indicated by the document. For instance, the summaries mention:

  • "The 510(k) Summary for K190896 describes the data that was used to support initial clearance of BriefCase." (page 11)
  • "The 510(k) Summary for K180647 describes the data that was used to support initial clearance of BriefCase." (page 15)
  • Similarly for K190072 (page 19), K193298 (page 23), K201020 (page 27), and K192383 (page 32).

Without access to the actual 510(k) Summaries for these predicate devices (e.g., K190896, K180647 etc.), I cannot describe the detailed acceptance criteria and the performance studies that originally cleared those devices. The provided document is a notification of intent to market a device based on substantial equivalence, not a summary of a new performance study.

In summary, based on the provided text, the answer to your request regarding K203508 is that a new study was not performed, as the submission argues for substantial equivalence based on a broadened user population rather than a change requiring new performance data.

§ 892.2080 Radiological computer aided triage and notification software.

(a)
Identification. Radiological computer aided triage and notification software is an image processing prescription device intended to aid in prioritization and triage of radiological medical images. The device notifies a designated list of clinicians of the availability of time sensitive radiological medical images for review based on computer aided image analysis of those images performed by the device. The device does not mark, highlight, or direct users' attention to a specific location in the original image. The device does not remove cases from a reading queue. The device operates in parallel with the standard of care, which remains the default option for all cases.(b)
Classification. Class II (special controls). The special controls for this device are:(1) Design verification and validation must include:
(i) A detailed description of the notification and triage algorithms and all underlying image analysis algorithms including, but not limited to, a detailed description of the algorithm inputs and outputs, each major component or block, how the algorithm affects or relates to clinical practice or patient care, and any algorithm limitations.
(ii) A detailed description of pre-specified performance testing protocols and dataset(s) used to assess whether the device will provide effective triage (
e.g., improved time to review of prioritized images for pre-specified clinicians).(iii) Results from performance testing that demonstrate that the device will provide effective triage. The performance assessment must be based on an appropriate measure to estimate the clinical effectiveness. The test dataset must contain sufficient numbers of cases from important cohorts (
e.g., subsets defined by clinically relevant confounders, effect modifiers, associated diseases, and subsets defined by image acquisition characteristics) such that the performance estimates and confidence intervals for these individual subsets can be characterized with the device for the intended use population and imaging equipment.(iv) Stand-alone performance testing protocols and results of the device.
(v) Appropriate software documentation (
e.g., device hazard analysis; software requirements specification document; software design specification document; traceability analysis; description of verification and validation activities including system level test protocol, pass/fail criteria, and results).(2) Labeling must include the following:
(i) A detailed description of the patient population for which the device is indicated for use;
(ii) A detailed description of the intended user and user training that addresses appropriate use protocols for the device;
(iii) Discussion of warnings, precautions, and limitations must include situations in which the device may fail or may not operate at its expected performance level (
e.g., poor image quality for certain subpopulations), as applicable;(iv) A detailed description of compatible imaging hardware, imaging protocols, and requirements for input images;
(v) Device operating instructions; and
(vi) A detailed summary of the performance testing, including: test methods, dataset characteristics, triage effectiveness (
e.g., improved time to review of prioritized images for pre-specified clinicians), diagnostic accuracy of algorithms informing triage decision, and results with associated statistical uncertainty (e.g., confidence intervals), including a summary of subanalyses on case distributions stratified by relevant confounders, such as lesion and organ characteristics, disease stages, and imaging equipment.
