This document describes the 510(k) premarket notification for the MEDISONO Color Doppler Ultrasound System, comprising models P11 Portable, P11 EXPERT Portable, P12 Trolley, P12 Expert, P25 Trolley, and P25 Expert Trolley.

Here's a breakdown of the acceptance criteria and study information provided:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are implicitly defined by the device's conformance to established industry standards and substantial equivalence to legally marketed predicate devices. The reported device performance is indicated by its ability to meet these standards and achieve the same intended uses as the predicates.

2. Sample Size Used for the Test Set and Data Provenance

The document states: "Clinical testing is not required." This indicates that no separate "test set" in the sense of patient data was used for a clinical study to prove efficacy, but rather, performance was established through non-clinical testing and comparison to predicate devices. Therefore, there is no information on sample size or data provenance from a new clinical test set.

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

Since clinical testing was not required and no new "test set" from patient data was analyzed by experts for ground truth, this information is not applicable and not provided in the document.

4. Adjudication Method for the Test Set

As no clinical test set requiring expert adjudication was conducted, this information is not applicable and not provided.

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 mention any MRMC comparative effectiveness study, nor does it describe any "AI" or human-in-the-loop performance evaluation. The device is a diagnostic ultrasound system, which typically involves direct use by a qualified physician, not an AI assistance evaluation.

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

This information is not applicable as the device is a diagnostic ultrasound system, not an AI algorithm. Its performance is inherent to its imaging capabilities, which are evaluated through technical standards and comparison to predicate devices, not as a standalone algorithm without human interaction.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

For the non-clinical testing, the "ground truth" implicitly refers to the established specifications and performance parameters as defined by the mentioned standards (NEMA, IEC, ISO). For the substantial equivalence determination, the "ground truth" is the established safety and effectiveness of the legally marketed predicate devices.

8. The Sample Size for the Training Set

As this is not an AI/machine learning device, there is no concept of a "training set" for an algorithm. Therefore, this information is not applicable.

9. How the Ground Truth for the Training Set Was Established

Since there is no training set mentioned, this information is not applicable.

Summary of the Study that Proves the Device Meets Acceptance Criteria:

The device's acceptance is based on demonstrating substantial equivalence to existing legally marketed predicate devices. The study proving this involved:

• Non-clinical testing: The device was tested to ensure it conforms to applicable acoustic output, electrical safety, and biocompatibility medical device standards. These standards (NEMA UD 2: 2004, NEMA UD3: 2004, IEC 60601-1:2012 A(2), IEC 60601-1-1, IEC 60601-1-2:2007, IEC 60601-2-37:2007, ISO 10993-5:2009, and ISO 10993-10:2010) represent the acceptance criteria for the technical performance and safety aspects of the device.
• Comparison to Predicate Devices: The submission highlights that the Medisono Color Doppler Ultrasound System (P11 Portable, P11 EXPERT Portable, P12 Trolley, P12 Expert, P25 Trolley, and P25 Expert Trolley models) incorporates the "same fundamental technology" as its respective predicate devices (Sonoscape S6, S8 Exp Portable, S11, S12, S20, and S22 ultrasound systems). It asserts that the subject device has similar technology characteristics, the same intended use, same design principle, same electrical classification, and same accuracy as the predicate devices. The conclusion drawn is that "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."

In essence, the "study" is a demonstration of conformance to regulatory standards and a thorough comparison to already cleared devices, rather than a novel clinical trial.

The provided text is a 510(k) premarket notification for a medical device (MEDISONO Ultrasonic Diagnostic Imaging System). 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 clinical studies in the way a novel AI/ML device might.

Therefore, the document explicitly states that clinical testing is not required (Page 32). This means there is no study described that involves patients, human readers, or an AI algorithm's diagnostic performance for the purposes of this submission. The "acceptance criteria" discussed are related to technical performance and safety standards, not clinical efficacy or diagnostic accuracy.

Based on the provided document, I cannot fulfill most of your request as it pertains to clinical performance and AI/ML evaluation metrics. The document is for an ultrasound imaging system, which is a hardware device for image acquisition, not an AI/ML diagnostic aid.

However, I can extract information related to the acceptance criteria for non-clinical performance and the testing done to meet them.

Here's what can be extracted from the document:

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

Based on the "Non-clinical Test" section (Page 32), the acceptance criteria appear to be compliance with specific international and FDA guidance standards for safety and performance of ultrasonic medical devices. The document states that these tests were conducted, implying the device met the requirements of these standards.

2. Sample size used for the test set and the data provenance:

• Sample Size: Not applicable. Non-clinical testing of compliance with standards typically does not involve "samples" in the sense of patient data sets. It refers to testing the physical device and its compliance with engineering and safety specifications.
• Data Provenance: Not applicable. No clinical data is referenced in this section.

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

• Not applicable. No "ground truth" in a clinical diagnostic sense is established or mentioned for this type of device submission. The tests are engineering and safety compliance tests, not diagnostic performance evaluations.

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

• Not applicable. Adjudication methods are relevant for human interpretation or AI performance studies, which were not required for this submission.

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:

• No. The document explicitly states "Clinical Test: Clinical testing is not required." Therefore, no MRMC study, AI assistance, or effect size comparison was performed or reported for this submission.

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

• No. This is an ultrasound imaging system, not an AI algorithm for diagnosis.

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

• Not applicable. The ground truth for this submission relates to the device meeting technical and safety specifications rather than diagnostic accuracy against a clinical reference standard.

8. The sample size for the training set:

• Not applicable. There is no mention of a training set as this is not an AI/ML device that learns from data.

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

• Not applicable. No training set is mentioned.

In summary, the provided document is a 510(k) premarket notification for a traditional ultrasonic diagnostic imaging system. It demonstrates substantial equivalence to predicate devices primarily through compliance with recognized performance and safety standards, rather than complex clinical performance studies involving AI/ML components.
