Radiography apparatus
Provided is a radiography apparatus capable of changing the shape and size at an imaging site. A radiography apparatus (1) includes a scintillator (12), and a substrate (11) that is laminated on the scintillator (12) and has a plurality of photoelectric conversion elements (17) converting light emitted from the scintillator (12) into electric charges, in which a laminate including the scintillator (12) and the substrate (11) is partitioned into a plurality of blocks (10A) to (10I), and the blocks are separable from each other.
X-RAY DIAGNOSTIC APPARATUS AND DISPLAY METHOD
According to an X-ray diagnostic apparatus, an X-ray tube radiates X-rays. An X-ray collimator adjusts an irradiation region of the X-rays. An X-ray detector includes a first detector and a second detector having a smaller detection area than a detection area of the first detector. The X-ray detector is able to detect the X-rays radiated with the first detector and the second detector at the same time. Processing circuitry generates a synthesized image obtained by synthesizing a first X-ray image generated based on an output from the first detector that detected the X-rays radiated in the irradiation region adjusted, and a second X-ray image generated based on an output from the second detector that detected the X-rays radiated in the irradiation region adjusted, the synthesized image having an image size corresponding to an aspect ratio of the irradiation region. The processing circuitry causes a display to display the synthesized image.
Active pixel radiation detector array and use thereof
Fabrication and use of an X-ray detector scan interface having separate enable and reset lines for each line (e.g., row) of pixels is described. In certain implementations, the respective enable and reset lines are connected such that activation of an enable line for a given line of pixels is concurrent with activation of a reset line for a different (e.g., preceding) row of pixels. In this manner, readout of one row of pixels is performed in conjunction with resetting the row of pixels readout in the preceding operation. In another technical implementation, a non-rectangular detector is divided into quadrants, with alternating quadrants configured for scan module or data module operations such that no quadrant has overlapping scan and data interconnections at the connection finger regions.

Semiconductor photodetection device, radiation counting device, and control method of semiconductor photodetection device
Noise of signals in an image sensor is reduced. A pixel circuit generates a reset signal of a predetermined initial voltage and an exposure signal of a signal voltage according to an exposure amount of light in order. An analog-digital conversion unit performs a reset sampling process of converting the reset signal into a first digital signal at a predetermined reset sampling interval and an exposure sampling process of converting the exposure signal into a second digital signal at an exposure sampling interval that does not exceed twice the predetermined reset sampling interval in order. A detection unit detects the light based on the first digital signal and a second digital signal.
STRUCTURED DETECTORS AND DETECTOR SYSTEMS FOR RADIATION IMAGING
Detector module designs for radiographic imaging include first and second layers of scintillator rods or pixel arrays oriented in first and second directions. The first and second directions are transversely oriented to define a light sharing region between the first and second layers. Encoding features may be disposed in, on or between the first and second layers, and configured to modulate propagation of optical signals therealong or therebetween.
