PG  - 787-94
AB  - A method is described for registering preoperative magnetic resonance (MR) to 
      intraoperative transrectal ultrasound (TRUS) images of the prostate gland. A 
      statistical motion model (SMM) of the prostate is first built using training data 
      provided by biomechanical simulations of the motion of a patient-specific finite 
      element model, derived from a preoperative MR image. The SMM is then registered 
      to a 3D TRUS image by maximising the likelihood of the shape of an SMM instance 
      given a voxel-intensity-based feature, which represents an estimate of normal 
      vector at the surface of the prostate gland. Using data acquired from 7 patients, 
      the accuracy of registering T2 MR to 3D TRUS images was evaluated using 
      anatomical landmarks inside the gland. The results show that the proposed 
      registration method has a root-mean-square target registration error of 2.66 mm.
