## Indications for use
The indications for use for the CORVUS Radiation Therapy Planning System have not changed as a result of this modification. The CORVUS system is a radiation treatment planning package designed to allow medical physicists, dosimetrists, and radiation oncologists to create conformal treatment plans using photon (x-ray) external beam radiation therapy. The treatment plans generated by CORVUS are based upon treatment machine-specific data and are intended to provide a guide to delivering external beam radiation therapy which conforms to the target volume defined by the radiation oncologist. The CORVUS System is valid for use only with external beam photon therapy; calculations for electrons and intracavitary sources (Brachytherapy) are not supported.
