TomoTherapy – Revolutionary Cancer Therapy

Designed for you.

The TomoTherapy Hi-Art SystemTM is a revolutionary way to treat cancer with radiation. With TomoTherapy, physicians can check the location of your tumor before each treatment, then deliver painless and precise radiation therapy based on a carefully customized plan. TomoTherapy combines precise 3D imaging from computerized tomography (CT scanning) with highly targeted radiation beams.

The TomoTherapy Hi-Art System introduces the two-step process:

Tomo-Graphy – A therapist can take a verification CT image (VRCT) before each treatment to make sure TomoTherapy treatment is targeted to the exact location of your tumor. Some types of tumors can change shape or even shift from day-to-day. With TomoTherapy's VRCT, the physician can be sure that each treatment is targeted right where it should be.

TomoTherapy – The TomoTherapy Hi-Art System uses a rotating beam of radiation that is constantly modulated to target the exact size and shape of your cancer. During treatment, the TomoTherapy Hi-Art System can focus radiation on the tumor area while minimizing damage to healthy tissue.

Before Each Treatment

Before each treatment, the therapist can take a VRCT image of the treatment site to check its exact size, shape, and most importantly, location. Because physicians can more accurately locate the tumor with the TomoTherapy Hi-Art System, they can reduce the amount of radiation that healthy tissues receive while concentrating the radiation where it is needed most - at the tumor site.

During Each Treatment

During TomoTherapy treatment, the radiation rotates 360 degrees, while the couch moves through the Hi-Art machine. While conventional radiotherapy delivers a wide beam of radiation from just a few directions, the TomoTherapy Hi-Art System can deliver small beamlets of radiation from every point on a spiral. The rotating TomoTherapy beam can accurately shape the radiation as prescribed by the physician and can treat both large tumors and multiple sites at the same time.

Unlike older radiation therapies, which required transferring patient data between several different stations, TomoTherapy is totally integrated. All patient information is contained in one unit.

TomoTherapy is the most advanced radiation delivery system available, delivering precise radiation to tumors while minimizing damage to surrounding tissues. And, the TomoTherapy system is available at the Hall-Perrine Cancer Center, serving all of Eastern Iowa and the entire Midwest (Missouri, South Dakota, Nebraska, Illinois, Minnesota and beyond).
