Low-dose CBCT reconstruction via joint non-local total variation denoising and cubic B-spline interpolation
Abstract This study develops an improved Feldkamp–Davis–Kress (FDK) reconstruction algorithm using non-local total variation (NLTV) denoising and a cubic B-spline interpolation-based backprojector to enhance the image quality of low-dose cone-beam computed tomography (CBCT). The NLTV objective funct...
