Radiation Oncologists | Prostate Cancer Treatment | TomoTherapy | Staten IslandThe TomoTherapy Hi·Art System®is a new, revolutionary way to treat cancer with radiation. With the TomoTherapy Hi·Art System®, the physician can check the location of the patient's tumor before each treatment, then deliver painless and precise radiation therapy based on a carefully customized plan. TomoTherapy combines precise 3-D imaging from computerized tomography (CT scanning) with highly targeted radiation beams.

 


What is TomoTherapy?

Radiation Oncologists | Prostate Cancer Treatment | TomoTherapy | Staten IslandTomoTherapy literally means "slice therapy," and gets its name from tomography, or cross-sectional imaging. The TomoTherapy Hi·Art System® delivers a very sophisticated form of intensity-modulated radiotherapy (IMRT), and combines treatment planning, CT image-guided patient positioning, and treatment delivery into one integrated system.

The equipment used for TomoTherapy looks much like a computed tomography (CT) system: the patient lies on a couch that moves continuously through a rotating ring gantry. The gantry houses a linear accelerator, which delivers radiation in the shape of a fan beam as the ring is turning. With the couch moving at the same time the gantry is rotating, the radiation beam makes a spiral (or helical) pattern around the patient, targeting tumors with optimal levels of radiation while minimizing the dose to healthy areas.

What are the advantages of TomoTherapy?

Radiation Oncologists | Prostate Cancer Treatment | TomoTherapy | Staten IslandThe advantages of TomoTherapy are having a radiation treatment beam projected into the tumor continuously as it rotates, rather than having a limited number of fixed beams, each providing only a fraction of the dose necessary to irradiate the tumor. With the TomoTherapy Hi·Art System®, physicians can adjust the size, shape, and intensity of the radiation beam to target the radiation to the size, shape, and location of the patient's tumor.

In addition, the new TomoTherapy Hi·Art System® integrates imaging with radiation treatment, which provides physicians with full three-dimensional information for accurate daily patient positioning. Its TomoImage® capabilities allow physicians to verify the position of the tumor before each treatment session, so adjustments can be made on the spot to make sure that radiation is delivered exactly where it should be.

How does TomoTherapy work?

The Tomo® Process combines treatment planning, CT image-guided patient positioning, and treatment delivery into one integrated system:
