Consider a 7beam IMRT treatment for prostate cancer T1N0M0 D

Consider a 7-beam IMRT treatment for prostate cancer (T1N0M0), Define the proper targets and organs at risk. Define an appropriate optimization cost function. Explain how a solution can be obtained.

Solution

A 7-beam intensity modulated radiation therapy (IMRT) is a therapy that can be used to deliver radiation therapy to the target organ without much side effects caused by external beam radiation therapy.

The target are prostate and seminal vesicles. The organs at risk are rectum, head of the femur and bladder.
