We designed and fabricated a novel three-channel endorectal prostate coil and validated its feasibility of high-resolution magnetic resonance imaging (MRI) at 3T. A commercial 3T surface coil was used for comparison. Both phantom imaging and in-vivo prostate imaging show that the 3-channel endorectal coil provides an improved SNR than the external surface coil. Prostate images at resolution of 0.47 mm × 0.47 mm × 4.0 mm are acquired using the 3-channel endorectal coil to demonstrate the performance. With the improved SNR and multichannel design, the proposed endorectal coil could enable parallel imaging based fast imaging in prostate imaging studies.
