Abstract: Provided is a radiation detector which includes a plurality of pixels for detecting radiation, each of the plurality of pixels including a radiation absorbing layer configured to convert incident radiation photons to electric signals; a plurality of comparators configured to compare each of the electric signals with a respective plurality of reference values, in order to classify the photons in a plurality of energy bands; and a plurality of counters configured to count and store the number of photons that are classified in each of the plurality of energy bands, and which have sizes which correspond to the plurality of reference values. Accordingly, the radiation detector may increase a measurable radiation amount without a requirement that sizes of the pixels or the sub-pixels are increased.

Abstract: A method of controlling an X-ray in a computed tomography (CT) apparatus includes: acquiring scout images of an object; setting an imaging region of the object in the acquired scout images; determining an outline of transverse axes lengths of the imaging region based on the transverse axes lengths of the imaging region; controlling X-rays emitted toward the object by adjusting a distance between elements of a transverse collimator of the CT apparatus according to the determined outline; and reconstructing a cross-sectional X-ray image of the object based on X-ray projection data generated by detecting the controlled X-rays.

Abstract: A method for storing X-ray data includes acquiring the X-ray data by using an X-ray detection module; and transmitting all or some of the acquired X-ray data to other X-ray detection module which is different from the X-ray detection module that has acquired the X-ray data.
