Embodiment Construction

[0036]A method of irradiating a target within a patient is provided. The method includes directing radiation beams from an external radiation source, such as at least one external radiation source, at a target within a patient over a wide solid angle from a multitude of directions (the directions can be so numerous as to be considered expansive). The external radiation source is rotated longitudinally about the axis about the patient. Simultaneously, with the longitudinal rotation or in any order (ie, before or after) relative to the longitudinal rotation, the external radiation source may be rotated latitudinally via translation along a circular trajectory. At the same time, the longitudinal and latitudinal rotation of the external radiation source actually moves the radiation source along a trajectory lying on the surface of the sphere. The latitudinal rotational range is sufficient to allow large non-coplanar beam angles at one or both ends of the rotational range. Prefer...

Abstract

A method of irradiating a target in a patient comprising directing a beam of radiation from an external source of radiation 24 at the target in the patient from numerous directions in a broad solid angle by longitudinally rotating the external source of radiation 24 around a central axis and simultaneously or sequentially, in either order, latitudinally rotating the external source of radiation 24; a globe gantry 21 comprising (i) a front opening ring 22 with its origin on the central axis of the globe gantry 21, (ii) at least one arc-shaped, gantry support arm 23, which has a front end and a rear end and is part of a circle, (iii) an external source of radiation 24, which is mounted on at least one arc-shaped, gantry support arm 23 and is movable along the gantry support arm to vary the latitude of the beam angle, (iv) a rear rotational axle 25 with an axis along the central axis of the globe gantry 21, (v) a support base 27, and (vi) a rear housing 26 comprising a source of power, mechanisms for moving components of the globe gantry 21, and controllers for controlling the movement of the components of the globe gantry 21 and the irradiation of the target in the patient; a system 20 comprising the globe gantry 21; and a method of irradiating a target in a patient using the system.

Description

[0001] Cross References to Related Applications [0002] This application claims co-pending US Patent Application No. 14 / 147,553, filed January 5, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to radiation therapy, and in particular, a method and system for delivering focused radiation from outside a patient's body to a target within the patient's body. The method and system aim to intensity modulate an external radiation beam from a wide solid angle to deliver a focal radiation dose to the target. Background technique [0004] Radiation therapy is used to treat cancer and other diseases in patients. About half of all cancer patients receive some type of radiation therapy at some time during the course of their treatment. A common form of radiation therapy is external beam radiation therapy. In external beam radiation therapy, beams of high-energy x-rays generated by a machine (usually a linear ac...
