Abstract
A threshold value T which is a little larger than voxel values of a target tissue such as bloodstream is determined. Next, a virtual ray is projected, and voxel values on the virtual ray are obtained as an array A(original array). Then, an array A(replaced array) is generated by the voxel values of the array Awhich are equal to or larger than the threshold value T are flipped-over at the threshold value T. Then, a part of the data on the array A, e.g., flipped-over data corresponding to the center part of the calcified region is excluded. Next, a maximum value Mon the array Ais obtained, and a value Mon the array Acorresponding to the value Mis obtained. Then, the value Mis employed as a pixel value for the virtual ray.
