SU-E-J-64: Landmark and ROI-Enhancement-Assisted Inter-Patient Deformable Registration of 3D Bladder CT Images.

Abstract

PURPOSE Deformable image registration (DIR) of the pelvis, and in particular, the bladder, is known to be a difficult problem. We tested several pre-processing strategies to improve the effectiveness of registration. METHODS We studied the use of automatically-derived landmarks (LMs) and enhanced regions of interest (ROIs) to improve existing DIR… (More)
