摘要: In an X-ray imaging device according to a first embodiment, an X-ray detector has a configuration in which scintillator elements are defined by light-shielding walls in a lattice shape. Among X-rays incident on the X-ray detector, X-rays incident on the light-shielding walls are not converted into scintillator light and are transmitted by the X-ray detector. Accordingly, by causing X-rays to be incident on the X-ray detector in which the scintillator elements are defined by the light-shielding walls in a lattice shape, an area in which X-rays 3a transmitted by a subject M are incident on the X-ray detector can be limited to an arbitrary range. Accordingly, since a detection mask can be omitted in the X-ray imaging device which is used for EI-XPCi, it is possible to reduce a manufacturing cost of the X-ray imaging device.

摘要: [PROBLEM TO BE SOLVED] To provide a radiation phase contrast imaging device having a small device configuration[SOLVING MEANS] The present invention focused on the findings that the distance between the phase grating 5 and the FPD 4 does not need to be the Talbot distance. The distance between the phase grating 5 and the FPD 4 can be more freely set. However, a self-image cannot be detected unless the self-image is sufficiently magnified with respect to the phase grating 5. The degree on how much the self-image is magnified on the FPD 4 with respect to the original phase grating 5 is determined by a magnification ratio X2/X1. Therefore, in the present invention, the magnification ratio is set to be the same as the magnification ratio in a conventional configuration. With this, even if the distance X2 between the radiation source 3 and the FPD 4 is reduced, a situation in which the self-image cannot be detected by the FPD 4 due to the excessively small size thereof does not occur.

摘要: In a method for manufacturing a radiation detector, counter pixel electrodes 33 are formed on a counter substrate 2 at positions facing a plurality of pixel electrodes formed on a signal reading substrate, and wall bump electrodes 34 are further formed on the counter pixel electrodes 33. In order to achieve the above, a resist R is applied, and the resist R is exposed to light to form openings O. When Au sputter deposition is performed on the openings O, only some of the Au is deposited on the bottom surface in the openings O as the counter pixel electrodes 33. The rest of the Au is not deposited on the bottom surface in the openings O, and the most of the remaining Au adheres to the inner walls of the openings O to form wall bump electrodes 34. The bump electrodes 34 are cylindrical, making it possible to reduce the pressure acting on the signal reading substrate by an extent corresponding to the decrease in the bonding area in comparison to conventional bump-shaped bump electrodes. The decrease in the bonding area also makes it possible to correspondingly improve the reproducibility of forming the diameter of the electrodes, and make reliable connection possible.

摘要: In a radiation detector, a Schottky electrode is formed such that an interdiffusion coefficient between the material of an outermost surface electrode formed on the Schottky electrode and the material of the Schottky electrode is smaller than an interdiffusion coefficient between the material of the outermost surface electrode and Al (aluminum). Consequently, the material of the outermost surface electrode does not diffuse into the Schottky electrode, and Schottky functions can be maintained, and at the same time, the material of the Schottky electrode does not diffuse into the outermost surface electrode, and the outermost surface electrode can be prevented from alloying.

摘要: Provided is a radiation phase difference imaging apparatus in which a separation distance between a phase grating and a radiation detector is optimized. The separation distance between the phase grating and a detection surface of an FPD is determined based on the magnitude of noise corruption in a self-image projected onto the detection surface. The magnitude of the effect of the noise is used as a basis for assessing the separation distance. It is determined whether a distance Zd is appropriate for imaging, based on the magnitude of noise corruption in the self-image in a self-image picture which is obtained when the distance Zd is the distance between the phase grating and the detection surface of the FPD. The separation distance can thus be optimized based on actual conditions of an actual X-ray source that emits a plurality of types of X-rays.

摘要: Provided is a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject. According to the present invention, it is possible to provide a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject immediately before. That is, the apparatus of the present invention is provided with a phase grating 5 provided with a subject area and a reference area. Both areas each have a predetermined pattern that absorbs radiation, but the patterns are different from each other. In this area, an image of the phase grating 5 is observed in a moire pattern of a long period. This moire image of a long period changes in the positions due to the minute change in the relative position between the phase grating 5 and the absorption grating 6, so it becomes possible to detect the minute change of the relative position between the radiation source, the phase grating 5, and the absorption grating 6 from the image of the reference area.
