B. A Cutting Edge Radiation Treatment Technology

Narrator: This is Science Today. Tomotherapy is cutting-edge radiation technology that allows doctors to visualize a tumor and apply radiation at the same time with pinpoint accuracy. This lessens the dose of radiation to normal, surrounding tissues or organs.

Vijayakumar: This is a new, emerging technology image guidance and in the coming years, this will become the standard. Image guidance means when we give the treatment, we can actually have the treatment guided by the images.

Narrator: Dr. Srinivasan Vijayakumar is chair of the University of California, Davis Cancer Center 's Radiation Oncology Clinic. The center is the first facility in Northern California to acquire and use this technology.

Vijayakumar: We treat almost all cancers in these image guided therapy machines. Mostly, anywhere the tumor is surrounded by sensitive, normal tissues is where this technology will be extremely useful.

Narrator: For Science Today, I'm Larissa Branin.
