Recently,development of Computer-Aided Diagnosis(CAD)technology is remarkable. CAD technologies for respiratory system are important,because they are useful not only for diagnosis but also for making surgical plans based on surgical simulation. But the conventional organ models can be only used for static analysis,and they are not applicable to dynamic analysis such as respiratory simulation. First,the SIFT(Scale-Invariant Feature Transform)is applied to a 4D-CT image to obtain key points and SIFT features on them. Next,by setting vertices of tetrahedra on the key points,a rough shape of the lung was represented as a set of tetrahedra. Then,the corresponding vertices in each time phase of 4D-CT image are tracked. Finally,we generate chest CT images at arbitrary time phase in respiratory cycle by calculating CT values in the tetrahedra by using interpolation. |
