3D Conformal Radiation Therapy
Three-dimensional (3D) conformal radiation therapy is a technique where the beams of radiation used in treatment are shaped to match the tumor. All of the beams of radiation are of the same strength. Multiple beams are directed toward the tumor, each coming from different angles. This technique avoids the healthy surrounding tissue while targeting the specific region determined by the planning program. By directing radiation to just the assigned target, it is possible to use higher levels of radiation for a more effective treatment in shrinking and killing tumors.
The specific treatment plan will be determined after evaluating your tumor’s shape and precise location. The physician will determine the treat schedule and how many sessions you may need for your particular case.
How is 3D conformal radiation therapy done?
First you will undergo a 3D image of your tumor with our CT simulator. Our physician and team then develops the treatment plan from the information obtained from the simulator.
The therapists will set up the 3D radiation therapy with a session that typically will take about 10-15 minutes.
- You will lie in the mold situated on the x-ray table.
- During the treatment, beams from several directions precisely match the tumor’s height, width, and depth will be directed towards your cancer site.
- The linear accelerator moves in a circular fashion around the tumor area.
- The actual treatment lasts only a few minutes.
The physician will determine your treatment schedule and how often you will need to repeat the treatment process.
