MillComp is used to manufacture compensators that are designed for radiation therapy treatment beams. MillComp may be used with any system that can design compensators such that the thickness over the area of the beam is specified at some known source to compensator distance in a plane perpendicular to the central axis. The thickness on an evenly spaced grid may be specified on divergent rays or on rays perpendicular to the plane of the compensator which is perpendicular to the central ray. If on divergent rays, the milled surface may be specified as towards the x-ray source or as towards the patient.
MillComp is a program that will write the tool path program to mill radiation therapy compensators on an end mill. Compensators are attenuators that are to be inserted into the x-ray beams for the purpose of modifying the field distribution over the area of the treatment beam. MillComp takes as input a compensator specification. The compensator specification will come from multiple sources, such as current therapy treatment planning systems, and is converted into a standard specification file format that MillComp can read. The conversion programs to read a compensator specification and write out the standard file format will be written on an as need basis according to the customer's needs. MillComp will read the specification file, generate the surface defined in the specification, and compute the tool paths necessary to cut the surface in solid lead, cerrobend, or other material, on a three axis end milling machine.
This document does not contain information about acceptance criteria or a study proving the device meets acceptance criteria. The provided text is a 510(k) summary and an FDA clearance letter for a device called "MillComp Version 1.0." This device is a program that generates tool paths for milling radiation therapy compensators.
The 510(k) summary focuses on describing the device's function and its intended use, which is to manufacture compensators for radiation therapy treatment beams. The FDA clearance letter confirms that the device has been found substantially equivalent to legally marketed predicate devices.
Therefore, I cannot fulfill your request for the following information based on the provided text:
- A table of acceptance criteria and the reported device performance
- Sample size used for the test set and the data provenance
- Number of experts used to establish the ground truth for the test set and their qualifications
- Adjudication method for the test set
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done and its effect size
- If a standalone performance study was done
- The type of ground truth used
- The sample size for the training set
- How the ground truth for the training set was established
§ 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.
