结局指标
主要结局
Prostate Volume on Actual MRI
时间窗: Within one month after the fiducial placement
A post-procedure MRI performed within one month after the fiducial placement.
Prostate Volume on US reconstruction
时间窗: During the fiducial placement
A US 3-D sweep will be performed during the fiducial placement.
Prostate Volume based on US/EM reconstruction
时间窗: During the fiducial placement
A 3-D US sweep performed during the fiducial placement and a Electromagnetic tracking data will also be acquired at the same time, and then the two series of data will be used for US/EM reconstruction.
