This work describes the design and simulation of an endorectal oil for MR-guided HIFU therapy of the prostate. MR-guided high intensity focused ultrasound (HIFU) is increasingly being investigated as a treatment option for prostate cancer. Due to space restrictions in the rectum, current prostate HIFU systems use external coils only. In this work an endorectal HIFU transducer is combined with an endorectal receive coil in a simulation study to assess the coil performance.
