I am a newbie interested in RadOnc. Can you guys please tell me what role a RadOnc plays during a gamma knife procedure ? Does he/she assist the neurosurgeon ? Can RadOncs do a neuro procudure with the Gamma knife without the n-surgeon ? Can RadOncs do non-neuro Gamma knife procedures without cooridation with other surgeons ? I would appreciate a discuss/education on RadOncs and the Gamma knife. Thank you.
