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.

Radiosurgery of cancers in the breast and the head using a single multi-source gamma-ray device

Preparing a plan to synchronize radiation delivery to a target in a patient with patient breathing phase and amplitude as the independent variable comprising (a) obtaining simultaneous data on patient breathing and target shape and location, (b) correlating the data and optimizing the correlation, (c) establishing optimal parameters of radiation delivery for each breathing phase/amplitude or for each target shape/location; and (d) synchronizing radiation delivery to a target in a patient with patient breathing comprising (a) positioning the patient, (b) monitoring actual breathing or the shape/location of the target, and (c) while monitoring, delivering radiation to the target according to a plan; and a system for controlling radiation delivery by a device to a target in a patient comprising (i) a processor, which receives and processes data on breathing or the shape/location of the target, and (ii) a controller, which controls radiation delivery to the target according to a plan, which synchronizes radiation delivery to the target with breathing data or the shape/location of the target.
