Paper Abstract

We have developed the algorithm and the computer program that constructs three dimensional image (3D) of soft tissue from multiple 2D slices of computed tomograph(CT) and magnetic resonance(MR) images. In construction of MR-3D, we have used multi-spin-echo images, and performed segmentation by comparing the curve-shape(intensity vs number of echo) of each pixel with a standard curve-shape that belongs to the desired organ. In the segmentation for CT-3D, we have used two kinds of threshold. In addition to CT value, we have used differential intensity of image as the threshold. The 3D micro-program has been installed in the Image Workstation of PACS. The position of observer's eye can be changed in less than a few seconds.
