Controller that Helps Imaging Precisely target Cancer Cells

Focused radiation continues to be an effective means to treat cancerous tumors, particularly when there is a clear-cut shot at the target. Finding that shot, however, is no simple task for clinicians for several reasons; the target is often surrounded by healthy tissue, it can grow, shrink or shift over time, and it is affected by changes in the patient's anatomy.

The Hi·Art® treatment system, a radiation therapy device that uses 3D CT imaging, was developed by TomoTherapy Inc., Madison, Wis., to address this challenge. The device leverages the ring gantry geometry used in CT scanning to deliver intensity-modulated radiation therapy (IMRT) from all angles around the patient, with minimal side effects More + Video>>
