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
