Virtual cone-beam computed tomography simulator with human phantom library and its application to the elemental material decomposition

Cone-beam computed tomography (CBCT) is essential in image-guided radiation therapy (IGRT) for accurate patient setup and dose distribution [1]. Three-dimensional (3D) information obtained from CBCT ensures precise patient positioning and treatment quality [2]. Reconstructing the actual dose distribution and monitoring differences from the planned dose in target areas and organs-at-risk (OAR) can be achieved using treatment planning with CBCT and machine logfiles [3,4]. Adaptive radiation therapy (ART) relies on the replanning on CBCT to optimize dose distribution based on changes in patient weight, target size, and anatomical deformations [5].
