There, are a few indigenously developed personal computers (PC) based treatment planning systems in India. They directly have many roles to play improve the quality of radiotherapy. In this paper, we present details of sources of inaccuracies that may arise in the PC based treatment planning systems and a few guidelines to correct them. From this study, it can be concluded that a thorough checking of the treatment planning systems is very much needed to know the limitations of the systems as well as the most appropriate ways in which the system can be used efficiently.
