Image Guided Radiotherapy Technology-Tomotherapy

In 2004, UAB became the first in Alabama and only fourteenth in the world to use TomoTherapy. TomoTherapy is an Image-Guided Radiotherapy (IGRT) technology that delivers radiation to the precise target treatment area while sparing the normal healthy tissue around it. It is a relatively new type of radiation method that delivers radiation helically (spiral shape), allowing radiation to be delivered more precisely to treatment sites that are difficult or impossible for conventional radiotherapy machines to reach.

TomoTherapy is a treatment and delivery system that integrates a linear accelerator with CT technology and a treatment planning system hardware and software. Because patient positioning is so vital to the effectiveness of a course of treatment, TomoTherapy technology provides a CT scan prior to each treatment. The CT confirms proper patient alignment, allowing adjustments to this alignment to be made when necessary prior to the delivery of the radiation. Lung cancer, head and neck tumors, breast cancer, prostate cancer, stereotactic radiosurgery and stereotactic body radiosurgery are some examples of treatments commonly performed using TomoTherapy.
