Abstract
An apparatus for composing and displaying a three-dimensional image comprises a device for computing a plurality of two-dimensional projected images from the same direction of a viewing line by a volume rendering scheme for each of a plurality of regions of interest set on three-dimensional data, a device for determining degrees to which each pixel of a plurality of two-dimensional projected images is involved in the display using the computed two-dimensional projected images and representative display surface depth values, each obtained for each pixel of the two-dimensional projected images, and a device for determining the total sum of the degrees of display involvement for each projection point and determining the pixel value of the projection plane.
