Combined Linear accelerator (LINAC) - MRI systems can provide image-guided radiotherapy treatment. These systems require splitting of the MRI scanner to provide a central gap large enough to ensure dual access for the accelerator and the patient. This raises technical difficulties for maintaining high gradient coil performance. In this research, a dedicated split transverse gradient coil was designed with a flange connected to the central coil end and compared to existing coil designs. It was found that a flanged-edge coil design produced manageable coil performance and eddy currents.
