A method for generating volumetric modulated arc therapy-computed tomography (VMAT-CT) including receiving, at a computer system comprising at least one processor, electronic portal imaging device (EPID) images collected during VMAT; performing Online Region-based Active Contour Method (ORACM) on the EPID images, resulting in binarized images; performing multi-leaf collimator (MLC) motion modeling on the binarized images, resulting in motion modeled EPID images with most of blurred regions within the EPID images removed; performing an outlier-filtering algorithm on the motion modeled EPID images, resulting in further filtered EPID images; executing a conventional FDK-based VMAT-CT reconstruction algorithm on the further filtered EPID images to provide FDK-reconstructed images; executing an iterative VMAT-CT reconstruction algorithm that combines compressed sensing and block matching and 3D filtering, on the FDK-reconstructed images, resulting in VMAT-CT images; and outputting the VMAT-CT images.
