The provided text is a 510(k) summary for the U-Lite PRO ultrasonic pulsed Doppler imaging system. It focuses on demonstrating substantial equivalence to predicate devices through technical comparisons and compliance with various standards, rather than providing detailed clinical study data with specific acceptance criteria and performance metrics for an AI/CADe (Computer-Aided Detection/Diagnosis) component.

Therefore, the document does not contain the information required to populate a table of acceptance criteria for AI performance, nor does it describe a study proving an AI/CADe device meets such criteria. Specifically:

• No acceptance criteria for AI were provided. The document describes acoustic output limits and measurement accuracy for the ultrasound system itself, but not for any AI/CADe features.
• No specific study proving AI performance was described. The document states, "No clinical studies were conducted," and the "Non-clinical Performance Testing" sections focus on electrical safety, EMC, usability, biocompatibility, and software verification/validation, along with acoustic output and measurement range/accuracy of the ultrasound hardware. There is no mention of a study to assess the performance of an AI algorithm in detection, diagnosis, or reader assistance.

Given the information provided in the document, it is not possible to complete the requested table or describe a study proving the device meets AI/CADe acceptance criteria, as the submission does not detail any AI component or its performance evaluation. The device described appears to be an ultrasound imaging device, not explicitly an AI/CADe system for image analysis.

There is no mention of a dataset of patient images or specific patient studies used for testing the device's diagnostic performance. Therefore, also no information on country of origin or retrospective/prospective nature of such data.

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

Since no clinical "test set" of patient data was used for evaluating diagnostic performance, there were no experts used to establish ground truth for such a set. The evaluation focuses on technical performance and safety compliance.

4. Adjudication Method for the Test Set

As no clinical "test set" was described, no adjudication method for a test set was mentioned.

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

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The document explicitly states: "No clinical study was conducted." This type of study would typically be performed to assess the diagnostic accuracy or effectiveness of the device with human readers, potentially comparing performance with and without AI assistance if AI were a component of the diagnostic process.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

No, a standalone performance evaluation was not described in the document. The U-Lite EXP is a general-purpose diagnostic ultrasound system, not an AI-driven algorithm with standalone diagnostic capabilities. Its functionality is to acquire and display real-time ultrasound data for human interpretation.

7. The Type of Ground Truth Used

The ground truth used for this submission is based on regulatory standards and technical specifications for ultrasonic diagnostic equipment. Compliance with these standards (e.g., for acoustic output, electrical safety, biocompatibility) serves as the "ground truth" for the device's safety and fundamental performance characteristics. No clinical "ground truth" (e.g., pathology, expert consensus on images, outcomes data) for diagnostic accuracy was utilized as no clinical study was performed.
