  • Patent number: 10732132
    Abstract: [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.

  • Patent number: 10729398
    Abstract: An X-ray phase contrast imaging device of the present invention can change an arrangement pitch of slits related to a multi-slit and an arrangement pitch of phase shift sections related to a phase grating. A positional relationship among the multi-slit 3b, the phase grating, and an FPD is determined based on the arrangement pitch of the slits related to the multi-slit, the arrangement pitch of the phase shift sections related to the phase grating, and an arrangement pitch of detection elements related to the FPD. Among these arrangement pitches, by changing the arrangement pitch of the slits and the arrangement pitch of the phase shift sections, the present invention can change the positional relationship among the multi-slit, the phase grating, and the FPD.

  • Patent number: 10393890
    Abstract: 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.

  • Patent number: 10365235
    Abstract: Provided is a radiation phase-contrast imaging device capable of assuredly detecting a self-image and precisely imaging the internal structure of an object. According to the configuration of the present invention, the longitudinal direction of a detection surface of a flat panel detector is inclined with respect to the extending direction of an absorber in a phase grating. This causes variations in the position (phase) of a projected stripe pattern of a self-image at different positions on the detection surface. This is therefore expected to produce the same effects as those obtainable when a plurality of self-images are obtained by performing imaging a plurality of times in such a manner that the position of the projected self-images on the detection surface varies. This alone, however, results in a single self-image phase for a specific region of the object.

  • Patent number: 10335109
    Abstract: 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.

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.

  • Patent number: 10295678
    Abstract: A X-ray detector having enhanced X-ray sensitivity, which enables dual energy imaging having high diagnostic performance. This X-ray detector includes: scintillator elements which are partitioned by light blocking walls and which convert low-energy X-rays to light; and scintillator elements which are partitioned by light blocking walls and which convert high-energy X-rays to light. When seen from the direction of incidence of the X-rays, the positional pattern of the light blocking walls and that of the light blocking walls are configured so as not to be in alignment with each other. Accordingly, the X-rays incident on the X-ray detector are converted to light by at least either one of the scintillator elements and are finally outputted as X-ray detection signals.
