The Victoreen Thebes II, Model 7020, is used to perform dose distribution measurements and analyses on radiation therapy beams.These measurements and analyses may be used for acceptance testing, beam trimming, routine beam checks and quality assurance measurements.
The Victoreen Thebes II, Model 7020, consists of a linear detector array consisting of 47 waterproof, vented air ionization chambers; a multi-channel electrometer with 48 independent electrometers; and Windows based software that acquires beam profile data from the detector array and multi-channel electrometer, displays the measured beams one dimensional dose distribution profile graphically and performs beam profile analysis.
The provided text is a 510(k) premarket notification letter from the FDA for a medical device called "Victoreen Thebes II Model 7020". This document focuses on the regulatory approval of the device and confirms its substantial equivalence to a predicate device.
It does NOT contain information regarding acceptance criteria, specific performance metrics, or study details such as sample size, data provenance, expert qualifications, ground truth establishment, or any comparative effectiveness studies (MRMC or standalone AI performance).
The document primarily states the device's indications for use: "The Victoreen Thebes II, Model 7020, is used to perform dose distribution measurements and analyses on radiation therapy beams. These measurements and analyses may be used for acceptance testing, beam trimming, routine beam checks and quality assurance measurements."
Since the requested information (acceptance criteria, performance data, study design, etc.) is entirely absent from the provided text, I cannot generate a response that directly answers your specific questions.
Therefore, I must state that the provided input does not contain the information necessary to describe the acceptance criteria and the study that proves the device meets them.
§ 892.5050 Medical charged-particle radiation therapy system.
(a)
Identification. A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. 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.
