Synopsis

Keywords: Interventional Devices, MR-Guided Interventions, Particle therapyElectromagnetic field simulations were performed at 1.5T to characterize the imaging capabilities of an RF body coil that is compatible with MR-guided radiotherapy and that can be rotated to achieve a flexible coil to fixed beam orientation. Transmit and receive field characteristics of the RF coil were calculated inside a phantom, and the homogeneity and power efficiency were analyzed for 24 different angles of rotation.
