摘要:
Provided are a radiographic imaging apparatus and a method of controlling the same. The radiographic imaging apparatus includes a radiographic source configured to emit radiographic rays in a discontinuous eigen energy spectrum, a radiographic detector configured to receive the radiographic rays, convert the received radiographic rays into electrical signals, and count the number of photons having energy that exceeds a threshold energy, and a controller configured to adjust the threshold energy by comparing an energy spectrum of the detected radiographic rays with the eigen energy spectrum of the emitted radiographic rays from the radiographic source.
摘要:
The X-ray imaging apparatus includes an X-ray generator to generate X-rays having at least two different energy levels and irradiate the X-rays onto a subject, a detector to detect the X-rays irradiated by the X-ray generator and transmitted through the subject, and a device to obtain images from the X-rays detected by the detector, to obtain bone image information and soft tissue image information of the subject, based on the obtained X-ray images, and to produce one image including the bone image information and the soft tissue image information.
摘要:
Disclosed are a radiation imaging apparatus, a computed tomography apparatus, and a radiation imaging method using the same. The radiation imaging apparatus includes a radiation emitter configured to emit radiation to an object while moving around the object, a radiation detector configured to detect radiation emitted from the radiation emitter and to change the detected radiation into an electric signal to thereby store the electric signal, and an irradiation controller to control the radiation emitter such that radiation is emitted to the object in at least one position or zone around the object and such that the radiation emitter stops emission of radiation to the object in a position or zone corresponding to the at least one position or zone.
摘要:
A computed tomography (CT) apparatus includes an X-ray source configured to generate X-rays; and a detector which is configured to detect the X-rays radiated by the X-ray source, and includes a counting detection region configured to generate X-ray data corresponding to the detected X-rays according to a photon counting method, and an integrative detection region which is configured to generate the X-ray data corresponding to the detected X-rays according to a charge integration method, and is formed on an outer portion of the counting detection region with respect to a rotation axis of a gantry.
摘要:
An emitter is configured to move around the object and to emit radiation toward an object. A controller is configured to control the emitter to stop a radiation emission, when the emitter is located in a radiation reception zone in which the radiation emitted by the emitter is received or in which the radiation emitted by the emitter is supposed to be received.
