Abstract: An X-ray detection system includes an X-ray generation device and an X-ray detector. The X-ray generation device includes an X-ray emission unit and a first sensor unit. The X-ray detector includes an X-ray reception unit for receiving X-rays from the X-ray emission unit, a data detection unit for detecting data from the X-ray reception unit, a second sensor unit, a computation unit for computing correction data using a distance between the first sensor unit and the second sensor unit, and a data correction unit for receiving a data signal from the data detection unit, receiving the correction data from the computation unit, and then generating corrected data.

Abstract: Provided is a radiation generating apparatus, including: a radiation generating unit for emitting radiation; and a movable diaphragm unit including a light projecting/sighting system for making a simulation display of a radiation field with visible light. The light projecting/sighting system includes: a light source of the visible light; a light guiding plate that is provided across a radiation axis, and causes the visible light from the light source to exit from a front surface of the light guiding plate; and a louver that gives directivity to the visible light exiting from the front surface of the light guiding plate.

Abstract: A radiation imaging apparatus includes an imaging unit and a handle unit detachably attached to the imaging unit. The imaging unit includes a digital radiation detector including a detection area, a housing incorporating the digital radiation detector, a power arranged on one side surface of the housing, and a display unit arranged on the one side surface and configured to indicate a state of the digital radiation detector. The handle unit includes a frame unit covering at least part of each of three side surfaces other than the one side surface of the housing and a grasping portion forming an opening between the handle unit and at least part of the one side surface, with the handle unit attached to the imaging unit.

Abstract: An arrangement for an X-ray image system with a grid frame arranged to enable the grid frame to oscillate is provided. The arrangement includes a switch unit, with which an anti-scatter grid inserted into the grid frame may be detected. An X-ray emission is only triggered by the switch unit at a predeterminable activation time if an anti-scatter grid is inserted.

Abstract: A radiation imaging apparatus is provided. The apparatus has moving means moving a pair of an X-ray tube and a detector relatively to an object. The apparatus further has means which acquire digital frame data outputted from the detector. The frame data are acquired from the same portion being imaged of the same object at different time points. The apparatus has means which use the frame data to produce a plurality of three-dimensional optimally focused images at the respective time points, an actual position and shape of the portion being imaged being reflected in the images, and means which estimate changes of the plural three-dimensional optimally focused images.
