WebBackground: In order to reduce the impact of CT radiation, low-dose CT is often used, but low-dose CT will bring more noise, affecting image quality and subsequent 3D reconstruction results. Objective: The study presents a reconstruction method based on wavelet transform-total variation (WT-TV) for low-dose CT. Methods: First, the low-dose … WebRecovered images using the hybrid method were obtained by minimizing an objective function that penalized the L2 distance with denoised images and the L2 discrepancy with …
