4D cone-beam computed tomography combining total variation regularization and motion compensation

Résumé

Breathing motion affects the image guidance of lung tumors when projection images are acquired using a slowly rotating cone-beam (CB) CT X-ray system while the patient breathes. Advanced methods have been developed to achieve streak-free and blur-free reconstructions, most of which are either based on motion compensation, or on regularization using some a-priori information.This paper introduces a method that combines both approaches, called Motion Compensated RecOnstructiOn using Spatial and Temporal Regularization (MC ROOSTER), and describes how it compares with its regularization-only counterpart (ROOSTER), with Motion Compensated FDK (MC FDK), and with respiration-correlated FDK.
