Abstract
Computerized techniques have long been applied in the field of biomedical imaging. In the past, the heavy burden induced by medical-related imaging or visualization process was always coupled with bulky and expensive workstation or servergrade computer. The recent advancement in graphics processing unit has unleashed the personal computer (PC) as the major platform for medical image processing, analysis, visualization as well as surgical simulation. In light of this, our group has worked out different high-performance computing techniques exploiting affordable PC graphics boards. These techniques include advancement in segmentation, rendering, deformation as well as surgical simulation. In this chapter, we discuss some of our advancements in this area with applications to biomedical imaging.
We discuss our experience in performing efficient tissue identification in the area of interest in different types of medical image. In particular, the latest advances in the processing of Chinese Visible Human (CVH) data are described. Different tissue can be identified within the images through semi-automatic methods. Based on the tissue-tagged images, we can further reconstruct structural models which represent different organs or tissues. The structural modelling process involves mesh generation and the development of appropriate mathematical models for simulating various operations being applied on the structures. In this part, we have proposed hybrid finite element models (FEM) which are computational efficient for processing of soft tissue deformation and other surgical procedure simulation. To demonstrate the practical application of our techniques, we also discuss our recent research and development process in various virtual reality (VR) surgical simulators, including virtual orthopaedic training and virtual knee arthroscopy.
