ABSTRACT
In m any fields o f physical and life sciences, h igher-d im ension stru ctu res are obtained by using low er dim ensions or 2D im ages. T hese m ethods need to im prove and im plem ented for b e tter understanding o f the o b je c t in concern. In field o f astronom y,
Bracewell [6] in his paper covered mathematical formulation of projections and reconstructions, introducing various significant relationships. Despite its potential, it had little impact in its field. However, in 1963, in the field of medicine [7] interest in tomographic reconstruction was shown. An X-ray computerized tomography (CT) scanner was developed, commonly known as the computerized axial tomography (CAT) scan. In 1979, for the above-mentioned application, a joint Nobel Prize was given to Cormack and Hounsfield. Success of the CAT scan lead to other medical analysis techniques like positron emission computed tomography (PET), ultrasound CT, and zeugmatography (reconstruction from nuclear magnetic resonance [NMR] imaging).
