An initial study on the estimation of time‐varying volumetric treatment images and 3D tumor localization from single MV cine EPID images

Abstract

The authors introduced a novel method of estimating volumetric time-varying images from single cine EPID images and a PCA-based lung motion model. This is the first method to estimate volumetric time-varying images from single MV cine EPID images, and has the potential to provide volumetric information with no additional imaging dose to the patient.
