Deformable Image Registration and Auto-Segmentation for Various Medical Imaging Types

Abstract

Current status of deformable image registration (DIR) and auto-segmentation for various medical imaging types (e.g., CT, MR, and CBCT) is reported. First, we introduce the advantage/disadvantage of DIR between (1) CT and CT, (2) CT and CBCT, (3) MR and MR, and (4) CT and MR. Next, we explain an atlas-based segmentation. Our explanation about DIR and auto-segmentation will help for understanding DIR technique.
