Radiation therapy treatment planning

Main steps in the Radiation Treatment Planning process 1. Define treatment volumes / risk organs 2. Define optimal beam setup 3. Calculate dose distribution within the patient and treatment times per beam (Monitor Units) 4. Plan evaluation Successful radiotherapy requires a uniform dose distribution within the target (tumor).  ICRU 50/62 recommends target dose uniformity within +7% and -5% of the prescribed tumor dose
