Abstract
Algebraic reconstruction methods are used widely for limited view tomography. They have been preferred with limited view and also with noisy data. Memory and compute intensive nature of these algorithms make it difficult to be used for higher resolution reconstruction. Present work encompasses a single view coded modified multiplicative algebraic reconstruction technique for circular and helical cone beam data collection geometries. The algorithm provides good results for (a) classical circular scan trajectory and (b) long object scanning performed with helical scan trajectory. Reconstruction results with real data indicate encouraging results for circular as well as helical scanning geometry.
