Moffitt Cancer Center Targets Tumors by Using More Precise Radiation Method

June 27, 2017

TAMPA, FL — Nearly two-thirds of all treated cancer patients in the United States receive some form of radiation therapy during the course of their illness, but delivering precise radiation is often challenging due to the movement of tumors and internal organs. However, clinicians at Moffitt Cancer Center are better able to aim radiation therapy directly at tumors, while avoiding surrounding tissues by using MRI-guidance.

Moffitt Cancer Center recently signed a deal to acquire ViewRay’s MRIdian Linac System, the world’s first and only FDA-cleared MRI-guided radiation therapy system, to assist with precision radiation. MRIdian Linac provides a unique combination of simultaneous radiation therapy delivery and continuous magnetic resonance imaging (MRI) for the treatment of cancer.

Because MRI technology eliminates the radiation exposure associated with computed tomography (CT) scans, MRIdian Linac allows for continuous imaging during the delivery of radiation therapy, allowing physicians to directly view and target the tumor during treatment. MRIdian Linac also enables physicians to personalize the treatment based on changes in the shape or location of the tumor and surrounding tissues using on-table adaptive therapy.

Moffitt’s Radiation Oncology Department, led by Louis Harrison, M.D., will use the MRIdian Linac for the delivery of highly conformal and personalized radiation therapy. They are specifically focused on the potential value of MRI to individually adapt radiation therapy dose distribution and fractionation as a function of unique patient parameters which the MRI can help elucidate. The Moffitt team will also pursue the delivery of high-dose radiation in fewer treatment sessions, and for real time, on-table adaptive therapy, which enables personalized treatments by adapting the treatment plan to changes in the shape, size, imaging characteristics and location of the tumor and nearby critical structures in each patient.
