Three (3) times per week, you will have a CT scan of your prostate. The CT scans will be performed just before the delivery of radiation. Radiotherapists will assist you onto the treatment table and position it for your treatment. The treatment table will then be rotated 180 degrees from the treatment machine and the CT scan of your prostate will be performed. After the CT scan, which will take about 5-8 minutes, the couch will be rotated back to the original position.
