    Abstract: This X-ray phase imaging system (100) includes an X-ray source (1), a detector (2), a first grating group (3), a second grating group (4), a moving mechanism (5), and an image processing unit (6). The moving mechanism is configured to relatively move a subject (T) and the imaging system (9) such that the subject (T) passes through a first grating region (R1) and a second grating region (R2). The image processing unit is configured to generate a first phase-contrast image (14a) and a second phase-contrast image (14b).

    Abstract: Disclosed is an X-ray apparatus with an X-ray tube controller. The X-ray tube controller controls an X-ray tube so as for X-rays emitted from the X-ray tube to have an energy width whose upper limit is more than the minimum K-shell absorption edge of K-shell absorption edges for elements forming a conversion film and is equal to or less than a preset value depending on a K-shell absorption edge corresponding to a characteristic X-ray whose energy influences the blur. Accordingly, the less number of ejected K-shell characteristic X-rays is obtainable than the case when the emitted X-rays have an energy width whose upper limit is more than a preset value depending on the K-shell absorption edge corresponding to the characteristic X-ray whose energy influences the blur. This allows a suppressed blurred image generated from ejected K-shell characteristic X-rays outside a pixel area where X-rays enter to introduce a photoelectric effect.

    Abstract: In an X-ray strip detector, at least one joining semiconductor film are formed on surface of a sensitive semiconductor film, on the part of X-strips and Y-strips, that is sensitive to incident X-rays to generate electric charge, and on at least an entire sensitive region of a conversion film. The joining semiconductor film has higher resistance value than resistance value of the sensitive semiconductor film. Accordingly, when the electric charge generated in the sensitive semiconductor film are collected in the X-strips and the Y-strips, movement of the electric charge into other adjacent strip electrodes is avoidable. Consequently, crosstalk can be suppressed that the electric charge leak to the adjacent strip electrodes.
