Paper Abstract

This paper focuses on tomographic reconstruction from a smaller number of projections than usual. Whereas traditional CT scanner are based on sequential X-ray sources, the proposed methodology in this work is based on simultaneous x-ray sources on each projection. Simulations have shown that only four projections are needed to reconstruct a slice, which are captured simultaneously, offering drastic reduction of image capture time. Algebraic Reconstruction Technique (ART) has been used for reconstruction. Although ART has many advantages over the established methods, it remained unpopular due to its high computational cost, and most importantly due to the artefacts caused by the patient's movement during image capture. The simultaneity of the projections helps to overcome this serious shortcoming of ART.
