Abstract
In an X-ray three-dimensional image display apparatus, a rotary encoder unit is employed which determines a window level and width of a two-dimensional image, and furthermore determines both upper and lower threshold limits in an X-ray CT (computerized tomographic) value of an X-ray tomographic image. The three-dimensional image display apparatus further includes a 3-dimensional image construction unit for constructing the 3-dimensional image from image data of a plurality of X-ray CT slices based upon the determined upper and lower limit values of the X-ray value. The rotary encoder unit includes D-type flip-flops which provide pulse signals to pulse counters.
