Abstract

This work aims to make use of compressed sensing to exploit the redundant nature hidden in the image and reduce the computational complexity involved in DRR generation. As a result, radiation risk to the patient can be reduced whilst maintaining an acceptable level of accuracy thus resulting in speed-up in DRR generation using the multiresolution approach compared to the conventional ray casting approach. Also in this research, different gradient based similarity metrics were compared on the basis of accuracy to achieve robustness against image content mismatch.
