Linear accelerators are the newest radiation technology available today. The machines produce and deliver radiation with precision that was previously unavailable -- accuracy down to the millimeter.

Computer-Ready Treatment

Linear accelerators at the Stanford Cancer Center are able to interface with computers to create advanced, targeted radiation therapy treatments such as intensity modulated radiation therapy (IMRT) and intraoperative radiation therapy (IORT).

These cutting-edge treatments are changing the landscape of cancer treatment, making radiation therapy an option for many more patients than ever before.


At the Cancer Center, technicians use your digitized imaging studies to precisely map out the tumor to provide very targeted radiation therapy. You are then assigned a digital file that holds your individual tumor target and radiation therapy information.


Because the linear accelerators are so accurate, it is important that you remain very still during treatment, which usually lasts about 10 minutes.

At the Cancer Center we go to great lengths to ensure that you are comfortable during treatment. You are given a full-size personalized mold to help stabilize your body during treatment, and a special face mask to stabilize your face comfortably. In addition, we play music in the room to help you relax.
