Stereotactic radiotherapy (also called "radiosurgery") is a form
of radiation therapy that simultaneously delivers narrow, powerful radiation
beams to a tumor from many directions. This type of radiation therapy
uses a three-dimensional set of coordinates to precisely target the beams
and is more protective of nearby healthy tissue. Here at Cancer Care Associates,
we're proud to be first in our South Bay area to be able to offer
stereotactic radiotherapy treatment utilizing the world's most technologically
advanced linear accelerator, the Truebeam®.
Truebeam® Radiation Therapy: Precise and Powerful
The Truebeam® is known for its extraordinarily high precision and flexibility
and its ability to deliver radiation that requires a highly exact setup
within very tight dose margins. Delivering sub-millimeter accuracy, the
Truebeam® facilitates accuracy with a precise beam center and a sharp
This particular form of stereotactic radiotherapy has several important
- The radiation beams conform exactly to tumor dimensions
- Radiation delivered by the Truebeam is exceedingly strong and flexible
- There is a significant decrease to the risk of damage to adjacent healthy tissue
- Built-in imaging technology captures high-resolution images of the target
at setup and during treatment delivery
- Delivery can be "gated" to match each patient's breathing cycle
- Truebeam ® works quickly, making treatment more comfortable for the patient
Collaborative Care, Individualized Treatment
Stereotactic radiotherapy treatment planning is individualized for each
patient. Our radiation oncologists collaborate with physicists and dosimetrists
to establish the optimal treatment plan, including number of visits, mode
of delivery and direction of beams. Neurosurgeons and pulmonologists may
also contribute to treatment planning.
While not optimal for all patients, Truebeam® is appropriate for tumors
that are located near the spinal canal as well as some small tumors in
the lungs, liver or brain.
Torrance Memorial Medical Center has two additional highly precise linear
accelerators for treatment of patients for whom Truebeam® therapy
is not optimal.
