Adaptive Backprojection : Developing a simple reconstruction algorithm

Abstract: This group project aims to investigate the possibility ofconstructing a prototype micro-CT-scanner, hopefullyfurthering the advancement in the field of small CT-scanners,with the ultimate goal to provide a structure useable in anambulance, to scan and send images to the hospital, so thattreatment can commence directly upon arrival.This report deals with the matter of reconstructing the takenimages to construct a three-dimensional model of thescanned object. An algorithm is developed in a mannerunderstandable to those not familiar with traditionalreconstruction techniques, simplifying the understanding ofCT backprojection while also providing a useful algorithm touse along with the scanner setup. The working principles ofthe reconstruction algorithm are explained along with itsdevelopment process, and the project ends with clear resultsin the form of an “Adaptive Backprojection” algorithm.
