摘要

The purpose of this research is to enable anybody to semiautomatically segment the anatomical structures in theMRIs, CTs, and other medical images on the personal computer. The segmented images are used for making threedimensionalimages, which are helpful in medical education and research. To achieve this purpose, the following trialswere performed. The entire body of a volunteer was MR scanned to make 557 MRIs, which were transferred to apersonal computer. On Adobe Photoshop, contours of 19 anatomical structures in the MRIs were semiautomaticallydrawn using MAGNETIC LASSO TOOL; successively, manually corrected using either LASSO TOOL or DIRECTSELECTION TOOL to make 557 segmented images. In a likewise manner, 11 anatomical structures in the 8,500anatomcial images were segmented. Also, 12 brain and 10 heart anatomical structures in anatomical images weresegmented. Proper segmentation was verified by making and examining the coronal, sagittal, and three-dimensionalimages from the segmented images. During semiautomatic segmentation on Adobe Photoshop, suitable algorithm couldbe used, the extent of automatization could be regulated, convenient user interface could be used, and software bugsrarely occurred. The techniques of semiautomatic segmentation using Adobe Photoshop are expected to be widely usedfor segmentation of the anatomical structures in various medical images.
