    Device Description

    The Theratron Elite consists of a source head, collimator, gantry, main frame, base, controls and a pendulum or beam-stopper style counterweight. The design of this device is similar to predicate devices Theratron 780E and 1000E. The key difference is that the 'push-button' style control console on the predicate devices has been replaced with a modern PC based remote control console with graphic user interface and 'Record and Verify' communication capability.

    AI/ML Overview

    The provided text describes a medical device, the Theratron Elite, which is a Cobalt Teletherapy device. The 510(k) summary indicates that the device's development and validation are in compliance with Theratronics product development procedures and that the validation demonstrates the device meets its published specifications.

    However, the provided documentation does not contain specific acceptance criteria values or detailed results from a study proving these criteria were met. It only states a general conclusion that the device performs "as well or better than the predicate device."

    Therefore, I cannot populate sections 1 through 9 of your request with specific numbers or detailed methodological descriptions because the information is not present in the provided text.

    Here's a breakdown of what can be inferred or what is explicitly missing:

    1. Table of acceptance criteria and the reported device performance:

    • Acceptance Criteria: Not explicitly stated with quantifiable thresholds. The summary mentions "published specifications" but does not detail them.
    • Reported Device Performance: Not explicitly stated with quantifiable metrics. The summary states it "performs as well or better than the predicate device" (Theratron 780E and 1000E).

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

    • Sample Size: Not mentioned.
    • Data Provenance: Not mentioned (e.g., country of origin, retrospective/prospective).

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

    • Not applicable as no specific test set or ground truth establishment process is described for performance evaluation.

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

    • Not applicable as no specific test set or ground truth establishment process is described for performance evaluation.

    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. This is a Cobalt Teletherapy device, not an AI-assisted diagnostic imaging or interpretation device that would involve human "readers." The primary comparison is to a predicate device's technical specifications and performance in delivering radiation, not human reading performance.

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

    • This question is more relevant to AI-driven diagnostic tools. For a radiation therapy device, the performance is inherently "standalone" in terms of its mechanical and radiation delivery capabilities. The device's "performance" would be related to accuracy of dose delivery, beam shaping, and safety controls, which would be tested without human "interpretation" in the loop beyond operational controls. The text mentions "development and validation" but doesn't detail the studies.

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

    • Not applicable in the context of diagnostic interpretation. For a radiation therapy device, "ground truth" would relate to manufacturing specifications, radiation physics parameters, safety standards, and potentially clinical outcomes if a clinical trial were conducted. The document states "device meets its published specifications," implying engineering and physics testing against known standards.

    8. The sample size for the training set:

    • Not applicable as this is not an AI/machine learning device requiring a training set in the conventional sense.

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

    • Not applicable as this is not an AI/machine learning device.

    Conclusion based on the provided text:

    The 510(k) summary for the Theratron Elite primarily focuses on establishing substantial equivalence to predicate devices (Theratron 780E and 1000E) based on its design, intended use, and general performance claims. It states that "The validation demonstrates that the device meets its published specifications, performs as well or better than the predicate device to which it is substantially equivalent, and is safe and effective for its intended use." However, it does not provide the specific data, metrics, or detailed study methodology that would allow for a comprehensive answer to your questions regarding acceptance criteria and performance study details.

    A Cobalt Teletherapy unit is a device by which gamma radiation is delivered for the treatment of cancer under the direction of health care professionals in a radiation therapy clinic.

    Device Description

    The Theratron 1000E consists of a source head, collimator, gantry, main frame, base, controls and a pendulum or beamstopper style counterweight. The design of this device is similar as the predicate device Theratron 1000 with improved safety features and radiation shielding in the collimator area of the unit head assembly.

    AI/ML Overview

    This document is a 510(k) summary for the Theratron 1000E. It describes a medical device, a Cobalt Teletherapy unit used for cancer treatment. The document states that the device's development and validation comply with Theratronics product development procedures and that the validation demonstrates the device meets its published specifications and performs as well as or better than the predicate device (Theratron 1000).

    However, the provided text does not contain the specific acceptance criteria, detailed results from a study proving these criteria were met, or most of the requested information about such studies. It is a summary statement of compliance for a 510(k) submission to the FDA, asserting that validation was done, but not describing the validation study itself in detail.

    Therefore, I cannot fulfill most of your request directly from the given text.

    Here's what I can provide based on the given information, and what is explicitly missing:

    1. Table of acceptance criteria and the reported device performance

    Acceptance Criteria (Inferred/Missing)Reported Device Performance (Inferred/Missing)
    Specific quantitative criteria are missing. The document generally states the device should:The document states: "The validation demonstrates that the device meets its published specifications, performs as well or better than the predicate device to which it is substantially equivalent, and is safe and effective for its intended use."
    - Deliver intended dose at specified position- Device demonstrated to meet specifications.
    - Deliver radiation according to selected relationship (fixed/moving beam, modifying device)- Device demonstrated to meet specifications.
    - Deliver radiation without unnecessary risk to patient, operator, others, or environment- Device demonstrated to be safe and effective.
    - Perform as well as or better than predicate device (Theratron 1000)- Device demonstrated to perform as well or better.
    - Have improved safety features- Design includes "improved safety features."
    - Have improved radiation shielding in collimator area- Design includes "improved radiation shielding in the collimator area."

    Missing:

    • Specific numerical or measurable acceptance criteria (e.g., dose accuracy within X%, leakage radiation below Y mSv/hr, specific safety interlock performance metrics).
    • Quantitative results demonstrating the device actually met these criteria.

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

    Missing: This information is not provided in the 510(k) summary. The document mentions "validation," but does not specify the sample size (e.g., number of units tested, number of measurement points) or the type of data (e.g., experimental data from a specific facility, clinical data).

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

    Missing: This is not applicable in the context of this device, which is a Cobalt Teletherapy unit, not an AI/diagnostic device that typically uses expert ground truth for interpretation. For a physical device, "ground truth" would be established by physical measurements and engineering specifications, often against industry standards or regulatory limits.

    4. Adjudication method for the test set

    Missing: Not applicable for a physical device performance validation in the way it's used for AI/diagnostic studies.

    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

    Missing: Not applicable. This is a physical radiation therapy device, not an AI-assisted diagnostic tool for human readers.

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

    Missing: Not applicable. This is a physical device, not an algorithm. Performance would be assessed based on its physical output (radiation dose, beam shaping, safety features).

    7. The type of ground truth used

    The "ground truth" for this device's performance would be:

    • Engineering Specifications: The device's design specifications for dose delivery, beam characteristics, and safety interlocks.
    • Regulatory Standards: Compliance with relevant national and international standards for medical electrical equipment and radiation safety.
    • Predicate Device Performance: The established performance metrics of the legally marketed predicate device (Theratron 1000), which the new device aims to match or exceed.

    Missing: The document does not explicitly detail these "ground truths," but rather asserts that the device meets its published specifications and performs as well as the predicate.

    8. The sample size for the training set

    Missing: Not applicable. This is a physical device, not an AI model that requires a training set.

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

    Missing: Not applicable.


    In summary: The provided text is a high-level regulatory summary for a medical device's 510(k) submission. It asserts compliance and substantial equivalence to a predicate device but does not contain the detailed study information (acceptance criteria, sample sizes, expert involvement, specific performance data) you requested. Such details would typically be found in the full design validation documentation or testing reports, which are not included here.
