Real-time interference compensation in MRI guided radiotherapy

Tech ID: T-019745

Technology Description

Researchers at Washington University in St. Louis have developed a method to improve image quality during MR imaging guided radiation therapy (MR-IGRT) by correcting for B0 fluctuation in real-time. The corrections reduce electromagnetic interference (EMI) between the MRI scanner and linear accelerator, which creates imaging artifacts.

Currently, EMI-related imaging issues prevent physicians from using more advanced volumetric modulated arc therapy (VMAT) techniques. VMAT use with MR-IGRT would dramatically reduce the procedure time per patient while improving tumor targeting.
