[Introduction] The photon radiosurgery system (PRS) is a newly developed compact radiosurgery system that irradiates soft X ray from the tip of its small probe(length=10cm,diameter=3 mm, weight of the machine =1.9Kg).

The PRS can be used either with a stereotactic frame or during a craniotomy as interstitial radiotherapy. ThePRS is able to irradiate 15 Gy at the portion of 1.5 cm from the center for about 20 minutes and avoid severe damage to surrounding normal brain because of steep dose distribution curve. Background exposure is minimal and no special shielding of the patient or health care personnel is required.
