Image guided radiation therapy (IGRT) has played a major role in the precision of radiation therapy especially while tracking moving tumors. The IGRT units are capable of 2D planar imaging, fluoroscopy etc. As lung tumor tends to move and deform during respiration, it also undergoes a sudden phase change in motion due to sudden cough or sneezing during the treatment which leads to the treatment beam missing the target. In this study we propose an algorithm for tracking moving tumors during radiation t...
