Research Development of Medical Image Deformable Registration Based on Model in the Application of Image Guided Radiotherapy
Zengjun Zhao · 2009
In order to make people have a broad understanding to the application of medical image deformable registration based on models in image guided radiotherapy,The recent publications that research the application of deformable registration in image guided radiotherapy are concisely classified and summed up according to the three major steps of deformable registration:the selection of deformable model and feature space,the selection of similarity metrics and space optimization,as well as the verification of deformable registration.The statistics of classification shows that the research directions of deformable image registration which basing to ensure the accuracy and precision of registration,are to combine different kinds of methods,such as multi-resolution,multilevel deformable registration,using parallel computing,and the combination of different kinds of optimization algorithms and so on,in order to shorten the registration time and to meet the clinical demands.
