Abstract
An apparatus and method of reconstructing a three-dimensional (3D) image from two-dimensional (2D) images are disclosed. Three dimensional (3D) data may be reconstructed in an x-ray generation tube at a limited angle, and repeatedly updated for each pixel. A median from among each pixel of reconstruction data may be selected. Backprojecting may be performed using a search direction weight calculated using a reprojection image and residual image. A 3D image satisfying a Level 1 (L1) norm fidelity and sparsity constraint of the reconstruction data may be reconstructed.
