Patients undergoing 3D-CRT spend more time in the scanner than traditional radiation therapy. These scans can take up to a couple of hours. After scans are complete, your medical team will create an individualized 3D-CRT treatment plan which can take up to a week or more.
On the next visit, patients will spend about half an hour lying down while receiving the radiation in a special treatment room. The treatment is painless and can be performed several times over the course of a few days.
