Abstract
Advancement of medical diagnosis device and computing technology leads the establishment of image guided therapy which realize precise guidance of treatment procedure using diagnosis images and medical image processing technologies. In this paper, I introduce the properties of these image modalities and technologies in the field of interventional radiology and minimally invasive surgery, including image enhancement and segmentation, registration, and organ motion estimation and tracking. On this technologies, we should define the requirement of accuracy and processing time for each treatment properly, based on clinical and engineering knowledge.
