20140016751 | X-RAY IMAGING APPARATUS, REMOTE CONTROLLER FOR X-RAY IMAGING APPARATUS, AND CONTROL METHOD FOR X-RAY IMAGING APPARATUS - Disclosed are an X-ray imaging apparatus, a remote controller for the X-ray imaging apparatus, and a control method for the X-ray imaging apparatus. The X-ray imaging apparatus includes a movable X-ray emitter to emit X-rays to a subject, a movable X-ray detector to detect X-rays emitted from the X-ray emitter and change the X-rays into electric signals, an input unit to receive target position information regarding at least one of the X-ray emitter and the X-ray detector, and a controller to control movements of the X-ray emitter and the X-ray detector according to the input target position information. | 01-16-2014 |
20140119495 | RADIATION IMAGING APPARATUS AND METHOD FOR RECONSTRUCTING IMAGE - Disclosed are an image reconstruction method and a radiation imaging apparatus using the same. The radiation imaging apparatus includes a radiation emitter which emits multiple energy spectra of radiation toward an object, a radiation detector which detects multiple energy spectra of radiation passing through the object and thereby outputs measurement data, and an image reconstructor which reconstructs a radiation image of the object, based on the measurement data output by the radiation detector. The method may be used to calculate simulation data of an inner structure of the object using an image reconstruction value including information associated with densities of substances of the inside of the object, to acquire a correction value of the image reconstruction value minimizing a discrepancy between the measurement data and the simulation data and to update the image reconstruction value using the correction value. | 05-01-2014 |
20140355735 | X-RAY IMAGING APPARATUS AND CONTROL METHOD THEREOF - Disclosed herein are an X-ray imaging apparatus capable of reducing a dose of radiation, and a control method thereof. The X-ray imaging apparatus includes: a gantry configured to rotate around an object, the object being placed on a table that is configured to be transported into a bore; a depth camera provided on the gantry, the depth camera configured to acquire a depth image of the object; an image processor configured to acquire thickness information of the object from the depth image of the object; and a controller configured to set a dose of X-rays to be irradiated to the object according to the thickness information of the object. | 12-04-2014 |
