  • 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.

    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.

  • Publication number: 20190135084
    Abstract: In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.
