The TBI Stand is used to safely support and reposition a patient for radiation therapy treatment in the vertical (standing) position when a physician desires to treat the patient with whole body irradiation by high energy photons or electrons, usually from a medical electron accelerator. At times, the physician utilizes the optional Scatter Screen to increase the surface dose to the patient during photon treatment.

At times, the physicians utilizes the optional Scatter Screen to increase the surface dose to the patient during photon treatment.
The provided document describes a 510(k) premarket notification for a medical device called the "TBI Stand." This type of submission is for demonstrating substantial equivalence to a predicate device, not for establishing novel clinical performance through acceptance criteria and a detailed study.
Therefore, the requested information regarding acceptance criteria, device performance, study details (sample size, data provenance, expert involvement, adjudication, MRMC study, standalone performance, ground truth, training set), and effect size cannot be extracted from this document, as these concepts are not applicable to a 510(k) substantial equivalence submission for the TBI Stand.
The document focuses on comparing the TBI Stand's technological characteristics to a legally marketed predicate device (MED-TEC Radio Therapy Treatment Chair K951947) to demonstrate that it is substantially equivalent and thus safe and effective for its intended use.
Here's a breakdown of what can be extracted related to the device and its comparison:
1. A table of acceptance criteria and the reported device performance:
Instead of "acceptance criteria," the document provides a "Predicate Comparison Table" which lists technological characteristics of both the predicate device and the TBI Stand. The "reported device performance" in this context is how the TBI Stand meets or exceeds these characteristics compared to the predicate.

Summary of why the other points cannot be answered:
- 2. Sample size used for the test set and the data provenance: Not applicable. This is a comparison of design and features, not a performance study involving a test set of data.
- 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 was established by experts for a test set in this context.
- 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No test set adjudication occurred.
- 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 device is a physical stand, not an AI or imaging diagnostic device that would involve human readers or AI assistance.
- 6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This is a physical device, not an algorithm.
- 7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable. The "ground truth" for a 510(k) of this nature is the established performance and safety of the predicate device, against which the new device's characteristics are compared.
- 8. The sample size for the training set: Not applicable. No training set is involved for this type of device submission.
- 9. How the ground truth for the training set was established: Not applicable, as there is no training set.

Dear Mr. Mick:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Fedgral Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613.

This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
