Pseudo-biologic plan scoring for treatment plan evaluation

Plan comparison is more and more important since the development of new modalities of radiation therapy such as conformal therapy, IMRT, radiosurgery, etc. However, plan comparison is not so simple. The traditional isodose comparison method is too subjective, the dose volume histogram analysis is not good enough for the case of crossing curves or for multiple organs. The uncomplicated tumor control probability is not practical for routine clinical application. In this study, we have developed the practical plan comparison method which uses pseudo-biologic plan scoring.
