TOMOSYNTHESIS IMPLEMENTATION OF MULTIPLE IMAGE RADIOGRAPHY

Multiple-image radiography (MIR) is an analyzer-based phase sensitive X-ray imaging method, which simultaneously generates three planar images containing information about absorption, refraction and scattering properties of the object. These three planar images are linear projections of the corresponding properties inside the object. The linearity of the projections allows reconstruction of volumetric images by computed tomography (CT) methods. In this work, we explore the use of tomosynthesis, a limited-angle tomography method, to reconstruct volumetric images of the object. We investigated the accuracy of reconstructions as a function of the number of angular views when the total object radiation exposure is fixed
