Abstract
A method of treating a cancerous region in a breast and/or in the head of a patient using a single radiosurgery device by placing the irradiation unit on an axle is disclosed. By pivoting the whole irradiation system, the treatment space can face different directions to accommodate the site of treatment. By continuously or sequentially pivoting the irradiation head unit and assigning different irradiation times to different pivoting angles, not only maximum degrees of expansion of the solid angle can be used for focusing the radiation beams to the target but also different regions of non-target tissues can have different shares of radiation doses based on how critical and radiation tolerant they are.
