The Digital Ultrasonic Diagnostic Imaging System is designed to be portable notebook ultrasound systems and mainly include the ultrasound equipment, transducer and adapter. The equipment to complete the ultrasonic imaging function, host completes the image display, measurement, patient information, image storage, and other applications Standard keyboards, touch panels, and buttons, as well as multifunctional editors, mainly control device operations. The display screen is used to display work interfaces, images, and parameters. Different interfaces are used to connect transducers, other devices, or power supplies. There are four different types of transducers, namely large convex, linear array, Micro convex, Intracavity, the frequency scope of different transducers is from 2.5MHz to 11MHz. The system provides a variety of modes for flexibly selecting, which include B-mode, M-mode, Color-mode, Power-mode, PW-mode, and combined modes (i.e., B/M- mode). Real time image and dynamic changes of tissues, organs or vessels will be showed in the image under B-mode, while coloring blood flow can be seen under Color-mode, PW-mode or Power-mode. M-mode is defined as time motion display of the ultrasound wave along a chosen ultrasound line. The system not only provides real-time tissues, organs or blood flow images, but also contains measurement of anatomical structures and analysis packages, which can offer diagnosticians detailed and useful information.

The provided document is a 510(k) Premarket Notification from the FDA for a Digital Ultrasonic Diagnostic Imaging System (Model: F6). This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the device meets specific acceptance criteria through a dedicated study with performance metrics.

Therefore, the document does not contain the detailed information requested regarding acceptance criteria and a study proving the device meets them in the way a clinical trial or performance study report would.

However, based on the information provided, here's what can be extracted and inferred:

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

The document doesn't present a formal table of acceptance criteria and reported device performance. Instead, it relies on demonstrating substantial equivalence to predicate devices, implying that the acceptance criteria are met if the device's technical characteristics and performance are comparable or don't raise new safety/effectiveness concerns.

The "Test Summary" section (6.1 Summary of Non-Clinical Tests) lists various international and FDA guidance standards that the device has been evaluated against. Meeting these standards is an implicit "acceptance criterion" for safety, electromagnetic compatibility, and basic performance.

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

The document explicitly states: "No clinical study is included in this submission." Therefore, there is no information about a test set sample size or its provenance in terms of patient data. The "tests" mentioned are non-clinical (bench testing) against standards.

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)

Since there was no clinical study, there is no mention of experts establishing ground truth for a test set.

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

Not applicable as there was no clinical test set.

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 device is a "Digital Ultrasonic Diagnostic Imaging System," which is a standalone imaging device, not an AI-assisted diagnostic tool that would involve human readers and comparative effectiveness studies.

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

This question typically applies to AI/software as a medical device. The device in question is a diagnostic ultrasound system. Its performance is assessed through its ability to generate images, measure, display, and analyze fluid flow, which is its inherent standalone function. The non-clinical tests listed serve to prove its performance in this standalone capacity by meeting established safety and performance standards relevant to ultrasound technology.

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

For the non-clinical tests, the "ground truth" would be the specifications and requirements outlined in the referenced standards (e.g., specific acoustic output limits, cytotoxicity thresholds, electromagnetic compatibility levels).

8. The sample size for the training set

Not applicable. This device is a diagnostic ultrasound system, not an AI/machine learning model that typically requires a training set of data.

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

Not applicable, as it's not an AI/ML device.

Pocket Ultrasound System(Model:P50,P51,P52,P53,P54,P55,P56) is intended for use by an appropriately trained, qualified physician for ultrasound evaluation. Specific clinical applications and exam types include: Abdominal, Obstetrics, Gynaecology, Small Parts (breast, thyroid), Peripheral Vascular, Urology. The system is suitable for use in hospital and clinical settings.

The Pocket Ultrasound System is designed to be high-end Pocket Ultrasound Systems and mainly include the ultrasound equipment and APP software components.6 models the the the main units are included in this submission, for including P50,P51,P52,P53,P53,P55,P56.

The equipment to complete the ultrasonic imaging function; APP complete the image display, measurement, patient information and image storage and other applications. APP can be deployed on Windows or Android devices which supported WIFI. There are two free APPs to support different systems. The communication protocol between APP and the system is specially defined by ourself, and other manufacturers can not use this protocol. The ultrasound device and the APP software transfer images and control instructions via WIFI.

Different type transducers are available for different model of Pocket Ultrasound System, the frequency scope of different transducer are from 3.5MHz to 6.5MHz.

The system provides a variety of modes for flexibly selecting, which include B-mode, M-mode, Color-mode, Power-mode, PW-mode, and combined modes (i.e. B/M- mode). Real time image and dynamic changes of tissues, organs or vessels will be showed in the image under B-mode, while coloring blood flow can be seen under Color-mode, PW-mode or Power-mode. M-mode is defined as time motion display of the ultrasound wave along a chosen ultrasound line, so it 's usually applied in diagnosis of cardiovascular diseases.

The system not only provides real-time tissues, organs or blood flow images, but also contains measurement of anatomical structures and analysis packages, which can offer diagnosticians detailed and useful information. The embedded software system along with the touch screen offer users a friendly and convenient graphical interface, which make users be able to easily control the whole system.

The provided text does not contain detailed information about acceptance criteria for an AI-powered device, nor does it describe a study proving the device meets specific performance criteria. Instead, it is a 510(k) summary for a Pocket Ultrasound System, which appears to be a medical device, but not explicitly an AI-powered one in the context of diagnostic assistance.

The document focuses on demonstrating substantial equivalence to a predicate device (Clarius Ultrasound Scanner, K192107) based on technical characteristics, intended use, and adherence to safety standards.

Therefore, I cannot fulfill the request for information regarding AI acceptance criteria and performance studies. The document explicitly states:

• "The subject of this premarket submission, Pocket ultrasound system did not require clinical studies to support substantial equivalence." This indicates that no human-in-the-loop clinical studies were conducted for this submission to evaluate diagnostic performance.
• The tests mentioned are primarily non-clinical tests verifying safety, electrical compatibility, biocompatibility, and acoustic output, along with software verification and wireless performance.

If this device were AI-powered and required demonstration of diagnostic accuracy, the information requested in your prompt (acceptance criteria, specific performance metrics, sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, standalone performance, training set details) would typically be found in a separate clinical performance study section, which is absent here.
