Exploring correlation information for image compression of four-dimensional computed tomography
2019
Quantitative Imaging in Medicine and Surgery
Nowadays four-dimensional computed tomography (4DCT) is popularly used in evaluating respiration-related organ motion for patients under radiotherapy. As consisting of multiple subsets of CT images, a larger storage space is needed for 4DCT. In this study, the correlations information within these subsets was explored and the popular video encoders were used for 4DCT image compression. The images of 4DCT subsets were arranged in an order and put into a sequence for the input of video encoder.
