What is it indicated for?

The Accuray Precision® Treatment Planning System is indicated for creation and assessment of external photon beam irradiation treatment plans for radiation therapy, stereotactic radiotherapy or stereotactic radiosurgery for lesions, tumors and conditions anywhere in the body when radiation treatment is indicated. A treatment plan provides an estimate of the dose distribution and the parameters utilized by the radiation delivery system. Plans must be reviewed and approved by qualified medical practitioners prior to delivery.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
