A digitized tomosynthesis method for projecting a 3D volumetric image of an object onto a virtual projection plane that comprises an alpha blend plane (15) subdivided into a rectangular array of pixel cells. A ray of energy defines a trace (17) representing a virtual sight path ray passing from a view point (13) through one pixel cell of the alpha blend plane (15) to define a view level image(19), wherein a 3D volumetric image of the object is projected by computing the coordinate of an object voxel referenced to the image plane, computing the image plane intercept of the ray of energy from the source through the object voxel, and forming a plurality of successively selected view level image planes (19) at the alpha blend plane (15). |
