New Medical Physics Study Findings Have Been Reported by Scientists at University of Wisconsin
November 15th, 2011
According to the authors of recent research from Madison, Wisconsin, "As a counterpart of 4DCT in the treatment planning stage of radiotherapy treatment, 4D cone beam computed tomography (4DCBCT) method has been proposed to verify tumor motion trajectories before radiation therapy treatment delivery. Besides 4DCBCT acquisition using slower gantry rotation speed or multiple rotations, a new method using the prior image constrained compressed sensing (PICCS) image reconstruction method and the standard 1-min data acquisition were proposed." "In this paper, the PICCS-4DCBCT method was combined with deformable registration to validate its capability in motion trajectory...
