Abstract
A system for stereotactic-guided radiation therapy, method of stereotactic-guided radiation therapy, and a collimator useful in treating a patient with stereotactic-guided radiation therapy includes a variable length pathway for the beam of radiation, the pathway having associated therewith a material substantially equivalent to the tissue of the patient, whereby the radiation beam always travels through the same distance of actual tissue and tissue equivalent material.
