Computerized tomography is extensively used in the medical imaging field. It has made a revolutionary impact in diagnostic medicine, helping doctors to view the internal organs of the human body to a very high precision, at the same time ensuring complete safety to the patient. This paper is a study of two such reconstruction algorithms, most commonly used in computerized tomography. They are the filtered backprojection algorithm and the fanbeam projection algorithm respectively. A comparison between the performances of the two methods has been carried out using a set of quality metrics. The experimental results and the conclusions drawn are also included. © 2010 ACM.
