Abstract: A computed tomography (CT) image processing apparatus and a CT image processing method are provided. The CT image processing apparatus may generate a virtual monochromatic image (VMI) by applying a weight to each of first, second, and third images corresponding to three different energy ranges. The CT image processing apparatus may set a region of interest (ROI) on a CT image, determine a VMI at an energy level at which a CNR of the ROI is at a maximum among a plurality of VMIs, and display the determined VMI.

Abstract: A tomography imaging apparatus and a tomography imaging method are provided. The tomography imaging apparatus includes a data acquirer configured to acquire first X-ray data of an object for each of energy bands, and an image preprocessor configured to perform a beam hardening correction on the first X-ray data for each of the energy bands, to generate second X-ray data of the object. The tomography imaging apparatus further includes an image reconstructor configured to reconstruct a tomography image of the object based on the second X-ray data.
