Paper Abstract

A technique for tomosynthesis utilizing a computed radiographic system is described in this paper. The process involves taking a series of radiographic images of an object at various angles using a linear motion tomographic unit and a scanning laser-stimulated luminescence plate as the image receptor. The digital image data obtained with the imaging plate system are transferred to a computer for tomographic reconstruction. The reconstruction algorithm utilizes the knowledge of the geometric scan data of the tomographic unit, and it shifts each angular projection in such a way that only one plane is in register when they are added together. This technique was evaluated using an anatomical phantom. The preliminary results offer tomographic images that are comparable to those obtained by the conventional film technique.
