Dose selection in stereotactic radiosurgery.
Selecting optimal doses for radiosurgery requires a thorough consideration of existing dose-response data for radiation injury of brain and surrounding structures and of the doseresponse for the desired endpoint (tumor control, obliteration of a vascular malformation, relief of trigeminal neuralgia, etc.). This paper reviews the radiobiological and physics principles that should be considered i...
متن کاملEvaluation of Dose Distribution in Intensity Modulated Radiosurgery for Lung Cancer under Condition of Respiratory Motion
The dose of a real tumor target volume and surrounding organs at risk (OARs) under the effect of respiratory motion was calculated for a lung tumor plan, based on the target volume covering the whole tumor motion range for intensity modulated radiosurgery (IMRS). Two types of IMRS plans based on simulated respiratory motion were designed using humanoid and dynamic phantoms. Delivery quality ass...
متن کاملDose-volume effects on brainstem dose tolerance in radiosurgery.
OBJECT Dose-volume data concerning the brainstem in stereotactic radiosurgery (SRS) for trigeminal neuralgia (TN) were analyzed in relation to associated complications. The authors present their set of data and compare it with currently cited information on brainstem dose tolerance associated with conventional fractionated radiation therapy and hypofractionated radiation treatment of other dise...
متن کاملEsophageal tolerance to high-dose stereotactic radiosurgery
PURPOSE Esophageal tolerance is needed to guide the safe administration of stereotactic radiosurgery (SRS). We evaluated comprehensive dose-volume parameters of acute esophageal toxicity in patients with spinal metastasis treated with SRS. MATERIALS AND METHODS From May 2008 to May 2011, 30 cases in 27 patients with spinal metastasis received single fraction SRS to targets neighboring esophag...
متن کاملDose distribution close to metal implants in Gamma Knife Radiosurgery: a Monte Carlo study.
Materials with high atomic numbers favor the occurrence of the photoelectric effect when they are irradiated with gamma rays. Therefore, the photoelectric effects of metal implants within the target regions in Gamma Knife Radiosurgery are worth studying. In the present work, Monte Carlo simulations using EGS4 were employed to investigate the resulting dose enhancements. A dose enhancement as hi...
