MRI Transrectal prostate biopsy requires updating of the targeted lesions while tracking the biopsy needle. Reliable tracking and fast, high resolution imaging require an optimized receiver. A novel external receive coil was designed to ensure higher signal from the prostate and from markers placed into a probe. The design was based on volunteer subjects and optimised for use with an MRI compatible manipulator. The sensitivity of the coil and the RF field homogeneity were evaluated. The results indicated significant improvements in sensitivity over the region of interest, with consequent improvements in needle tracking and imaging of the targets.
