Computed tomography scan simulation techniques: A survey

A Computed Tomography scan employs various combinations of X-ray images taken from different angles to create cross sectional images of specific portions of a scanned object. It allows the user to view the interior regions of the object without dismantling or cutting. This process is complex and involves a lot of parameters. Peak voltage of X-ray source, total number of scans needed, source to iso center distance, angle step and source to detector distance are some of the required parameters for the computed tomography scan. An incorrect scan procedure leads to heavy losses in terms of time and cost. Therefore simulation of computed tomography scan is required to avoid these losses. Scan simulation is a vital task for determining the scan plan for optimal reconstruction of a given object of interest. This paper presents the need for this scan simulation and a survey on the various scan simulation techniques used in medical and industrial applications. It also discusses the various issues associated with the scan simulation techniques.
