SU-F-BRF-06: Density Correction for Deformable Image Registration to Improve CT Number Mapping.

PURPOSE To improve the accuracy of CT number mapping inside the lung using deformable image registration for cases having substantially large lung volume differences. METHODS The deep-inspiration-breath-hold (DIBH) CT image and the end-of-exhalation (EE) phase image in 4DCT of three thoracic cancer patients were enrolled in this study. The lung volumes… (More)
