AI/ML Overview

Here's a summary of the acceptance criteria and the study information based on the provided text, formatted to your requests. However, please note that the document is a 510(k) summary for a radiotherapy system, which focuses on demonstrating substantial equivalence to a predicate device for regulatory approval. It is not a clinical study of an AI/ML device, and therefore many of the requested fields related to AI performance, ground truth establishment, and expert involvement are not applicable or not provided in this type of document.


Acceptance Criteria and Device Performance

This document describes a medical device (TrueBeam, TrueBeam STx, Edge, and VitalBeam radiotherapy systems) that has undergone updates. The "acceptance criteria" here refer to conformance to regulatory standards and a demonstration of substantial equivalence to a predicate device, rather than performance metrics for an AI algorithm. The performance is assessed through verification, validation, and safety standards testing.

1. Table of Acceptance Criteria and Reported Device Performance

Since this is not an AI/ML device with specific performance metrics like sensitivity, specificity, or AUC, the "performance" here refers to compliance with safety and functional standards.

Acceptance Criterion (Implicit)Reported Device Performance

Safety ProfileResults of verification, validation, and safety standards testing demonstrate no changes to the safety profile of the device. Outcome: The product conformed to the defined user needs and intended uses, and there were no discrepancy reports (DRs) remaining which had a priority of Safety Intolerable. Therefore, the device is substantially equivalent to the predicate device.

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

This document describes a regulatory submission for a radiotherapy system, not an AI/ML diagnostic or prognostic device that typically uses "test sets" of patient data for performance evaluation in the typical sense. The testing described is primarily hardware and software verification and validation, along with compliance to international standards. Therefore, information about a "sample size for a test set" or "data provenance" (country, retrospective/prospective) related to patient data for AI evaluation is not applicable and not provided in this document.

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

Given that this is not an AI/ML device being evaluated for diagnostic or prognostic accuracy on patient data, the concept of "ground truth" and "experts establishing ground truth" in the context of a "test set" is not applicable here. The "experts" involved would be engineers, physicists, and regulatory specialists confirming compliance with technical and safety standards.

4. Adjudication Method for the Test Set

As this is not an AI/ML study involving human interpretation of data where adjudication is needed, an "adjudication method" is not applicable and not described in the document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, an MRMC comparative effectiveness study comparing human readers with and without AI assistance was not done and is not relevant for this type of medical device submission. This document pertains to a radiotherapy treatment delivery system, not an AI-assisted diagnostic or interpretation tool.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was done

This is not applicable as the TrueBeam is a medical linear accelerator for radiation therapy delivery, not an AI algorithm intended for standalone performance evaluation in the way this question implies. Any "algorithms" (e.g., iCBCT reconstruction) are components of the system, and their performance is evaluated as part of the overall system's functional and safety requirements, not as standalone AI products.

7. The Type of Ground Truth Used

The "ground truth" in this context is the adherence to established engineering, safety, and regulatory standards, along with the device's functional specifications. It's established through:

  • Engineering specifications and design documents: Dictating how the device should perform.
  • International Consensus Standards: Like IEC 60601 series, IEC 62304, ISO 13485, ISO 14971, which define safety and performance requirements.
  • Verification and Validation Testing: Empirical testing to confirm the device meets these specifications and standards.
  • Clinical use (implied/previous predicate data): The safety and efficacy of radiation therapy itself, and the predicate device, form the basis. The current submission demonstrates that the updated device maintains that safety and efficacy.

It is not expert consensus on patient pathology, or outcomes data in the sense of a clinical trial for a novel AI diagnostic.

8. The Sample Size for the Training Set

This is not applicable as the device is not an AI/ML system that undergoes "training" on a dataset in the typical machine learning sense. The development of the device follows traditional engineering design, verification, and validation processes. While some components like the iCBCT algorithm might involve data for development, the concept of a "training set" for the whole system, as understood for AI, isn't present in this document.

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

Since there is no "training set" in the AI/ML context for the device as a whole, this question is not applicable. In the case of component algorithms (like iCBCT), any "ground truth" for their development would be based on known physics, simulation data, and expert validation of imaging quality, but this detail is not provided in a 510(k) summary focused on substantial equivalence.
