Device Description

This SonoScape P20 Elite Series Digital Color Doppler Ultrasound System is an integrated preprogrammed color ultrasound imaging system, capable of producing high detail resolution intended for clinical diagnostic imaging applications.

The basic principle is that system transmits ultrasonic energy into patient body and implements post processing of received echoes to generate onscreen display of anatomic structures and fluid flow within the body.

This system is a Track 3 device that employs a wide array of probes that include linear array, convex array and phased array.

This system consists of a mobile console with touch screen and keyboard control panel, power supply module, color LCD monitor and optional probes.

This system is a mobile, general purpose, software controlled, color diagnostic ultrasound system. Its basic function is to acquire ultrasound data and to display the image in B-Mode (including Tissue Harmonic Image), M-Mode, TDI, Color-Flow Doppler, Pulsed Wave Doppler, Continued Wave Doppler, Power Doppler and Directional Power Doppler Imaging, or the combination of these modes, Contrast Imaging, Elastography, 3D/4D.

AI/ML Overview

The provided FDA 510(k) summary (K221140) describes the Sonoscape P20 Elite Series Digital Color Doppler Ultrasound System. This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study for software performance and acceptance criteria for an AI/ML powered device.

Therefore, the information required to answer your request (acceptance criteria, study details, sample sizes, expert qualifications, adjudication, MRMC studies, standalone performance, ground truth details, and training set information) is not available in the provided text.

The document discusses general performance tests related to electrical safety, EMC, acoustic testing, and software verification/validation, but these are for the overall ultrasound system's hardware and embedded software, not for an AI/ML algorithm within the system.

The "P20 Elite Series" system includes some "newly added features in Function" such as "contrast imaging, Color 3D, S-Live/S-Live Silhouette/S-Live Contour, S-Depth, STIC, 3D/4D HyCoSy, SPI, Micro F, SR Flow, Auto Face, VCI and etc." and "new features (Measurement Items), including AVC Follicle, Auto OB, Auto NT, Auto EF, Auto bladder, Auto IMT and etc."

For these new functions, the summary states:

They are "the same as or similar with the imaging functions of the reference device S60 Elite Series/S70 Series Digital Color Doppler Ultrasound System (K201059)" for imaging functions.
They are "the same as or equivalent with the measurement functions of the reference S60 Elite Series/S70 Series Digital Color Doppler Ultrasound System (K201059)" for measurement items.
"The differences in function and measurement items will not raise new risk and different questions of safety and effectiveness."
"The end user can edit, accept, or reject the measurements and can modify the measurement results at any point. The final output and its accuracy is controlled by the end user."

This indicates that these functions are either manual or assisted measurement tools where the final decision rests with the user, and their performance is deemed similar to existing cleared devices, not necessarily validated through specific AI/ML performance studies with acceptance criteria as you've requested.

Conclusion: The provided text does not contain the detailed information regarding acceptance criteria and performance studies for an AI/ML powered device as outlined in your request. The submission focuses on demonstrating substantial equivalence of a general-purpose ultrasound system to a predicate device based on technical characteristics and safety standards.

Compared with the predicate device P60 Series (K171000), the Subject Device P20 Elite Series have some new features (Measurement Items), including AVC Follicle, Auto

{7}------------------------------------------------

OB. Auto NT, Auto EF, Auto bladder, Auto IMT and etc., which are the same as or equivalent with the measurement functions of the reference device S60 Elite Series/S70 Series Digital Color Doppler Ultrasound System (K201059). The end user can edit, accept, or reject the measurements and can modify the measurement results at any point. The final output and its accuracy is controlled by the end user.

The differences in function and measurement items will not raise new risk and different questions of safety and effectiveness. Therefore they can be considered Substantially Equivalent in safety and effectiveness, the SE is not affected.
