Paper Abstract

Three dimensional surface reconstruction and visualization are well recognized to be useful in the area of pre-operative surgical planning and radiation treatment therapy planning. This function has been integrated into the capabilities of the comprehensive PACS system of the Harbor-UCLA Diagnostic Imaging Center. This paper describes how the user can transfer and view CT or MR images from the scanners on the radiation treatment node thru SYNERCOM* or microwave. Afterwards, an interactive segmentation algorithm is used to isolate an arbitrary region of interest and gray level thresholding is applied to generate an intermediate bin'ary image. A ray tracing algorithm is used for visible surface formation and a shading value is then calculated. Different views of the object can be generated by interactive manipulation of the rotational angles. The final 256 x 256 images are shown in cine-mode on a color Deanza 5512 system.
