RADIATION IMAGING DEVICE

Provided is a radiation imaging device capable of 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 device capable of precise imaging without performing pre-imaging in the absence of a subject. Specifically, this device is provided with a phase grating 5 having a subject region and a reference region. Both regions have a predetermined pattern that absorbs radiation, the patterns being different from each other. In this region, a long-period moiré-like image of the phase grating 5 is observed. Since the long-period moiré-like image changes the position thereof with a minute change in the relative positions of the phase grating 5 and an absorption grating 6, it is possible to detect a minute change in the relative positions of a radiation source, the phase grating 5 and the absorption grating 6 from an image of the reference region.

RADIATION PHASE DIFFERENCE IMAGING APPARATUS

Provided is a radiation phase difference imaging apparatus in which a separation distance between a phase grating and a radiation detector is optimized. That is, according to the present invention, the separation distance between the phase grating 5 and a detection surface 4a of an FPD 4 is determined based on the magnitude of noise corruption in a self-image projected onto the detection surface 4a. In other words, in the configuration of the present invention, the magnitude of the effect of the noise is used as a basis for assessing the separation distance. According to the present invention, 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 5 and the detection surface 4a of the FPD 4. The separation distance can thus be optimized based on actual conditions of an actual X-ray source 3 that emits a plurality ...

RADIATION PHASE-DIFFERENCE IMAGING DEVICE

The present invention focused on the fact that the distance between a phase grating 5 and an FPD 4 does not need to be the Talbot distance. The distance between the phase grating 5 and the FPD 4 can be more feely set. However, a self-image cannot be detected unless the phase grating 5 in the self-image is satisfactorily magnified. The degree to which the original phase grating 5 in the self-image is magnified on the FPD 4 is determined by a magnification factor X2/X1. Therefore, in the present invention, the magnification factor is set to be the same as the magnification factor in the conventional configuration. By doing so, even if the distance X2 between a radiation source 3 and the FPD 4 is decreased, a situation in which the self-image cannot be detected by the FPD 4 due to the minute size thereof does not occur.

X-RAY IMAGING APPARATUS

An X-ray imaging apparatus 1 according to Example 1 comprises an X-ray detector 5 having a configuration wherein scintillator elements are defined by a lattice-like light shielding wall. A portion of X-rays incident on the X-ray detector 5 is incident on the light shielding wall and passes through the X-ray detector 5 without being converted to scintillator light. Therefore, since the X-ray detector 5 that receives X-rays has the scintillator elements defined by the lattice-like light shielding wall, arbitrarily defined, more limited regions of the X-ray detector 5 are allowed to receive X-rays 3a that have passed through a subject M similarly to when X-rays pass through a detection mask. Thus a detection mask from the X-ray imaging apparatus 1 which is used in the EI-XPCi method can be dispensed with, allowing manufacturing costs of the X-ray imaging apparatus 1 to be reduced.

Radiation Phase Contrast Imaging Device

[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 X 2/ X 1. 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 X 2 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.

Touch panel device

Surface acoustic waves are propagated in a lower-left oblique direction and a lower-right oblique direction from an excitation element located on the upper side of a non-piezoelectric substrate and then received by receiving elements located on the left side and the right side, while surface acoustic waves are propagated in an upper-left oblique direction and an upper-right oblique direction from an excitation element located on the lower side of the non-piezoelectric substrate and then received by the receiving elements located on the left side and the right side.
