Research on the principle and application of high voltage of the Elekta accelerator / 中国医学装备

ABSTRACT

Objective:Through getting acknowledge of the High-voltage of medical linear accelerator, it makes it possible for the relative medical workers to do a quick reaction to the repairmen and maintenance to the accelerator, and to maintain the machine to a good performance efficiently. While through understanding the application situation and development of accelerator, we could do a better choice at the terms of choosing an accelerator for hospital which meet the basic requirements and accuracy.Methods: Using the block diagram to introduce the main part of High-voltage of medical linear accelerator, and especially introduce the charging pinciple of charging transformer and the charge and discharge of PFN. The accelerator plays a vital fuction at radiation therapy, and we introduce the accelerator application in various fields and the development situation of technology application.Results: It’s significant to know the working principle of High- voltage as it’s helpful to ensure whether the machine works normal or not and to diagnose faults in it.Conclusion: In addition, through understanding the application situation and the development of accelerator, we could choose an appropriate accelerator for our hospital.
