Patent ID: 6961911

Claim:
A display method far displaying three-dimensional data as a combination of three sectional images of an X-section, a Y-section, and a Z-section orthogonalizing each other, by processing a three-dimensional data obtained by such as CT imaging, said method comprising the steps of: preparing in advance sectional images of sections parallel to said X-section, Y-section, and Z-section, said sectional images being sliced off data from said three-dimensional data at a predetermined interval, displaying on three display parts as a three sectional displaying mode a X-sectional image, a Y-sectional image, and a Z-sectional image, each selected from said prepared sectional images, together with an X-cursor, a Y-cursor, and a Z-cursor, each of which specifies a section of said corresponding sectional images, and when, on any one of said three display parts, at least one of said cursors displayed together with said sectional images is moved, sequentially changing a sectional image to be displayed corresponding to the moved cursor on another display part different from the display part where the cursor was moved, following the moving of the cursor, in a manner that said sectional image to be displayed on said other display part is selected from said sectional images.
