Abstract

An apparatus to deliver conformal radiotherapy using external beam Cobalt 60 source is disclosed. The apparatus comprises an enclosed circular gantry placed above the bearings along with an integrated in house X-ray unit with the X-ray detector, source head and beam stopper. The X-ray unit along with the X-ray detector of the enclosed circular gantry are aligned to the radiation beam plane such that 3-D image of the tumour can be constructed using a cone beam computed tomography (CBCT) and radiation treatment is delivered by beam limiting device, without moving the patient from one patients treatment couch to other thus reducing the inconvenience to the patient achieving high tumour positioning accuracy and for alignment of X-ray and radiation beams.

Description

technical field [0001] The present invention relates to an apparatus for delivering conformal radiation therapy through the use of external beams of cobalt-60. In particular, the present invention relates to a radiotherapy device that provides greater precision in tumor localization and reduces the need for frequent calibration to align x-ray and radiation beams. Background technique [0002] Radiation therapy has seen multiple advances over the past few decades. Many of these advances have been made through improvements in computers, imaging, dose calculations, treatment planning tools, and beam-shaping hardware. Intensity-modulated radiation therapy (IMRT) is the next logical step, enabling physicists to follow dose distributions to treat desired targets while pulling away from normal structures. Cobalt-60 has been used extensively in conventional non-IMRT radiation therapy in the past. [0003] Radiation therapy itself can be divided into two main categories: internal ...
