This paper focuses on the theoretical inverse design of cylindrical head RF phased array coils applied in the Magnetic Resonance Imaging Linear accelerator (MRI-Linac) system. A MRI-Linac system is the combination of cancer detection and real time, image guided radiotherapy. In this work, a RF phased-array coils with gaps are designed. Those gaps provide easy access for the accelerator without any disturbance, and multiple receiver coils can realize the fast imaging requirements. The simulation results show that homogeneous magnetic field within a given region of interest (ROI) can theoretically be achieved by the new designed coil.
