Development of Embedded Based Anti-Collision Technique for Medical LINAC (Linear Accelerator) Machine

Abstract

In Linear Accelerator, there may be possibility of misalignments of machine elements, which can cause an accident to patient and machine itself. Hence tight limits are imposed on machine tolerance, design parameters and methods of machine operation. The objective of the work is to improve the work efficiency of machine and high operation speed, accuracy and the most important factor is safety of patient & equipment. Microcontroller provides convenient control, well-designed display, and more comprehensive diagnostics and error logging can increase safety. In order to focus more sharply our efforts to the possible impact of machine-Patient collision problem, we have developed a formula and list of entries that have the potential for the most serious consequence for the patient machine collision. The calculations are done in such a way that there is no chance of collision and result in patient and equipment safety. Our method correctly confirmed clearance for patient couch and gantry. In conclusion, we have developed a embedded based device form lookup table method for collision detection that is accurate, easy to implement, and computationally inexpensive.
