Abstract:

In a 3D conformal radiotherapy treatment （3D CRT） planning, the 3D visualization technology is necessary to the acquiring of 3D visual information and to the target determination. This paper develops a 3D visualization system of the 3D CRT planning. In the system consisting of the function modules such as image segmentation, muhi-modality image registration and fusion, 3D reconstruction, 3D recognition and target contour delineation, the fusion of muhi-modality image is realized by means of the wavelet transform-based fusion method and the fusion rule through the combination of the local standard deviation and the local energy, and the volume rendering of 3D images is rapidly implemented via the improved Shear-Warp method. Experimental results demonstrate that the proposed system helps to well implement the visualization in 3D CRT planning.
