摘要
Abstract
This paper proposed a registration algorithm for thoracic and abdominal PET/CT images from the perspectives of multi-transformation and multi-optimization policies in order to correct the image deformation and registration error caused by respiratory motion. Then a registration system for PET/CT images with good interactivity and user-friendly interface was designed and implemented based on ITK (Insight Segmentation and Registration Toolkit), VTK (Visualization Toolkit) and QT. Experimental results showed that the elastic registration algorithm proposed in this paper can correct the image deformation and registration error and had great advantages in its accuracy over other algorithms that used single transformation and optimization.关键词
