Design and Preliminary Clinical Studies of an MRI-Guided Transrectal Prostate Intervention System

Figure 2: Targeting images, needle visualization images, and gold marker image of clinical procedure using the transrectal prostate intervention system. Top image row: Suspicious targets (red cross hairs) were selected on axial TSE T2-weighted images. Second image row: The needle tip void was visualized in axial TSE proton density images. The desired targets match the actual position of the needle. Error number: The number indicates the in-plane targeting error for the needle placement. Third image row: Axial TSE proton density image showing the location of the marker placed at target location number 1. The marker void is visible close to the target.
