Risk evaluation of the kilovoltage radiotherapy practice

Abstract

The kilovoltage radiotherapy is a recently re-implemented practice in the National Institute of Oncology and Radiology of Cuba to treat patients. One of the problems to approve its use is the assessment of risks associated to this practice. The present paper shows a summary of the pattern of accidental sequences proposed for this practice and its risk is quantified by using the risk matrix methodology. The SECURE-MR code has been used as the tool selected to implement such a practice. In addition to customary analysis facilities, this code has some other novel characteristics allowing us to establish the contributors’ priorities. The global results of the risk assessment for the proposed pattern, as well as some particular optimization practices are included in this paper.
