Gantry- Couch/ Gantry- Patient collision is a serious problem in various medical equipments in radiotherapy. This collision may cause damage to the machine or even may cause injury to the patient. In this article, an efficient method of avoiding collision that is inherent in the radiotherapy machine is presented. The study uses an intelligent co-ordinate geometry based algorithm for avoiding collision in machines. The overall computation takes less than 0.1 seconds for sensing the collision. Also this new technique for avoiding collision is tested with two different radiotherapy machines namely Imagin and Bhabhatron-II. This is a faster and accurate method of avoiding collisions in complex iso-centric set-ups.

Abstract


Gantry- Couch/ Gantry- Patient collision is a serious problem in various medical equipments in radiotherapy. This collision may cause damage to the machine or even may cause injury to the patient. In this article, an efficient method of avoiding collision that is inherent in the radiotherapy machine is presented. The study uses an intelligent co-ordinate geometry based algorithm for avoiding collision in machines. The overall computation takes less than 0.1 seconds for sensing the collision. Also this new technique for avoiding collision is tested with two different radiotherapy machines namely Imagin and Bhabhatron-II. This is a faster and accurate method of avoiding collisions in complex iso-centric set-ups.
