A method of reconstructing a tomographic image in a medical imaging apparatus includes: acquiring a first image of an object and a second image of the object corresponding to an image to be reconstructed; determining, in the first image, a reference region corresponding to a unit region in the second image; and updating data in the unit region based on data contained in the reference region. Thus, a medical image having both high spatial resolution and high temporal resolution is reconstructed to have substantially reduced artifacts.

An apparatus for capturing a radiation image of a subject including at least two materials includes a radiation irradiating unit configured to irradiate multi-energy radiation including at least two energy bands to a calibration model including a plurality of thicknesses of each of the at least two materials; an attenuation-coefficient estimating unit configured to estimate attenuation coefficients for each of the at least two materials for each of the at least two energy bands based on values obtained by passing the multi-energy radiation through the calibration model; and an energy-band determining unit configured to determine an optimal combination of at least two energy bands to be included in multi-energy radiation to be irradiated to the subject from a plurality of different combinations of at least two energy bands based on the estimated attenuation coefficients and the values obtained by passing the multi-energy radiation through the calibration model.

Disclosed is a high-resolution image reconstruction method using a focal underdetermined system solver (FOCUSS) algorithm. The method comprises the steps of: outputting data for an image of an object; downsampling the outputted data; transforming the downsampled data into low-resolution image frequency data; and reconstructing a high-resolution image from the transformed low-resolution image frequency data by applying focal underdetermined system solver (FOCUSS) algorithm.
