AI/ML Overview

The provided document describes Medisono's submission for 510(k) premarket notification for several digital color Doppler ultrasound systems. The submission asserts substantial equivalence to a set of predicate devices.

Here's an analysis of the acceptance criteria and the study information as requested:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in a quantitative manner (e.g., target accuracy, sensitivity, or specificity metrics) that would typically be seen for AI-driven diagnostic devices. Instead, the performance demonstration focuses on showing equivalence to predicate devices through technical comparisons and non-clinical testing. The performance is assessed against the established safety and effectiveness of the predicate devices.

Acceptance Criterion (Implicit)Reported Device Performance
Safety and Effectiveness Equivalence to Predicate DevicesAffirmed: Non-clinical product evaluation (software verification and validation, performance testing (measurement accuracy), acoustic testing, EMC, doppler sensitivity, and safety testing per IEC standards) demonstrates the Medisono devices perform comparably and are as safe and effective as the predicate devices.
Software FunctionalityConfirmed: Software verification and validation conducted; documentation provided per FDA guidance. Software considered "moderate level of concern."
Measurement AccuracyConfirmed: Performance Testing included measurement accuracy for various distance and area measurements.
Acoustic Output and Electrical SafetyConfirmed: Acoustic output testing per IEC 60601-2-37, and safety testing per IEC 60601-1 and IEC 60601-1-2 standards were performed.
EMC (Electromagnetic Compatibility)Confirmed: EMC measurements were performed.
Doppler SensitivityConfirmed: Doppler sensitivity measurements were performed.
Technical Characteristics Equivalence (e.g., display modes, gray scale, storage, cine review, depth adjustment, image conversion, annotations, body mark, USB port, display, operating voltage/frequency, capacity, battery life, dimensions)Confirmed: Detailed comparison tables (pp. 9-20) show nearly identical or equivalent technical specifications and features for each Medisono device compared to its respective predicate device. The only noted difference is the absence of network connectivity for Medisono devices.
Intended Use EquivalenceAffirmed: The intended uses of the Medisono devices are similar to those of the predicate devices for diagnostic ultrasound imaging of various body parts and patient populations in a clinical setting.

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

The document does not specify details about a "test set" for performance evaluation in terms of patient data. The provided performance evaluation is primarily based on non-clinical testing on the devices themselves (e.g., measurement accuracy, acoustic properties, safety standards adherence) rather than clinical studies with patient data. Therefore, information about sample size, country of origin, or retrospective/prospective nature of a clinical test set is not present.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

As the performance evaluation relied on non-clinical testing and comparison to predicate devices' specifications, there is no information about a "ground truth" derived from expert review of patient data.

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

Since there is no mention of a test set with patient data requiring ground truth established by experts, there is no information on an adjudication method.

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

The document does not describe a multi-reader multi-case (MRMC) comparative effectiveness study involving human readers or AI assistance. The devices in question are diagnostic ultrasound systems, not AI algorithms designed to enhance human reader performance.

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

The document describes the Medisono devices as "Ultrasonic Diagnostic Imaging System models," which are hardware systems with integrated software for image acquisition, processing, and display. The software itself is considered "moderate level of concern" and underwent verification and validation. However, the submission does not detail a standalone "algorithm only" performance study in the context of an AI/ML algorithm separate from the device's inherent functioning. The performance tests are for the overall device's measurement accuracy, acoustic output, and other core technical functions.

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

For the "performance testing (Measurement Accuracy)," the ground truth would typically be established by known physical standards or phantoms with precise dimensions for distance and area measurements. For acoustic and EMC testing, it would be against defined regulatory standards (e.g., IEC standards). This is not human-derived ground truth from clinical data.

8. The sample size for the training set

The document does not mention a "training set" of data, as is common for AI/ML algorithms. The software verification and validation are for the device's operational software, not an AI model that learns from data.

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

As there is no mention of a training set, there is no information on how ground truth for a training set was established.

Evaluation of similarities and differences:

The Medisono MS55 Plus, P25 Expert, P12 Plus, and P11 Plus have similar intended use, functionality, similar technologies as well as safety and performance characteristics than the Sonoscape P60, Sonsoscape P20, Sonoscape P15, and Sonoscape S8, respectively. The Medisono models P9 Plus and P3 Plus have similar intended use, functionality, similar technologies as well as safety and performance characteristics as the Chison Eco 5, Chison Eco 2 ultrasound systems respectively. There are no differences among the Medisono devices and the corresponding predicate devices except for device network connectivity as the Medisono devices are not intended to be connected to a network.

Conclusion:

The subject device has similar technological characteristics and has similar intended use and functionality as the predicate devices. There are no differences between the devices that affect the usage, safety and effectiveness, thus no new question is raised regarding the safety and effectiveness. The non-clinical performance test data and software verification demonstrate that the Medisono MS55 Plus, P25 Expert, P12 Plus, P11 Plus, P9 Plus, P3 Plus performs comparably to and it is as safe and effective as the predicate devices. In accordance with the 21 CFR Part 807 and based on the information provided in this premarket notification, Medisono MS55, P25 Expert, P12 Plus, P11 Plus, P9 Plus, P3 Plus is substantially equivalent to the predicate that is currently marketed for the same intended use.
