AI/ML Overview

The provided document, a 510(k) Summary for the CHISON 8300 Digital Ultrasonic Diagnostic Imaging System, focuses on demonstrating the device's technical performance and safety rather than a clinical study involving human subjects or AI algorithms. Therefore, many of the requested elements for describing a study proving the device meets acceptance criteria are not directly applicable or available in this specific document.

The "acceptance criteria" discussed in the document are primarily related to the measurement accuracy of the ultrasonic imaging system itself, using various probes.

Here's an analysis based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document states that these accuracy tests were "conducted" and "display the measurement accuracy," implying the reported performance matches or is better than the acceptance criteria given in the "Accuracy" column.

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

The document describes "Accuracy Test was conducted for the effectiveness". However, it does not specify the sample size used for these accuracy tests. It also does not provide data provenance (e.g., country of origin, retrospective/prospective). This appears to be a technical validation of the device's measurement capabilities, likely using phantoms or controlled objects, rather than a clinical study on patient data.

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

This information is not provided in the document. Given the nature of an "accuracy test" on an ultrasonic system's measurements, the ground truth would likely be established using highly precise physical measurements on test objects or phantoms, not necessarily by medical experts interpreting images.

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

This information is not provided and is generally not applicable to the type of technical accuracy testing described here.

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 MRMC comparative effectiveness study was done as described in the document. The device is a diagnostic ultrasound imaging system, and the filing primarily focuses on its fundamental technical performance and safety, not on the performance of an AI algorithm or human reader improvement with AI assistance. The document predates widespread AI integration in medical devices (2007).

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

No standalone algorithm performance study was done. The device itself is an imaging system; it does not feature an independent algorithm requiring standalone performance evaluation in the context of this 510(k) submission.

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

The ground truth used for the "Accuracy Test" would most likely be physical measurements or calibrated reference values from test phantoms or controlled objects. The document implicitly indicates this by listing accuracy specifications for axial distance, lateral distance, circumference, area, and heart rate within specific measurement ranges. These are quantifiable technical performance metrics.

8. The sample size for the training set

This is not applicable as the document describes a traditional diagnostic ultrasound imaging system and its technical performance, not an AI/ML-based device that would require training data.

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

This is not applicable for the same reasons as in point 8.

§ 892.1560 Ultrasonic pulsed echo imaging system.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
