Intended Use
  • The indications for use are applicable as previously presented for pReference TPS (K970464), such intracranial diseases as gliomas, neuromas, meningiomas, astroctyomas, arteriovenous malformations, and metastatic carcinomas.
  • The indications for use of pReference Treatment System are expanded to include lesions requiring extracranial stereotactic radiotherapy or radiosurgery. These include hepatic, pancreatic, retroperitoneal, paraspinal, skeletal, and prostatic tumors.
  • The software is used to electronically import CT images containing the target to be irradiated, to determine the precise location of the target with respect to implanted fiducials, to define and visualize treatment beam locations, and to visualize dose to the target and other structures.

AI/ML Overview

The provided text does not contain information about acceptance criteria, device performance, study design, or ground truth establishment. This document is an FDA 510(k) clearance letter for the "pReference Treatment System," which is a treatment planning system. It outlines the device's indications for use and confirms its substantial equivalence to a predicate device.

Therefore, I cannot populate the requested information. The document focuses on regulatory clearance rather than a detailed performance study.

§ 892.1000 Magnetic resonance diagnostic device.

(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
