    • Provided is an X-ray imaging apparatus and a method of X-ray imaging, with which the apparatus can be reduced in size and a differential phase image or a phase image with consideration of an X-ray absorption effect of an object can be obtained.X-rays are spatially split, and a first attenuation element in which the transmission amount of X-rays continuously changes in accordance with the displacement when the X-rays pass through an object is used. Transmittance is calculated by using the first attenuation element and a second attenuation element that is different from the first attenuation element with respect to an amount of change or a characteristic of change in the transmission amount of X-rays in a direction of a displacement of the X-rays. A differential phase image and the like of the object are calculated using the transmittance.

    • According to one embodiment, a power supply circuit includes a power switch section, an error amplifier, a wiring and a reset switch section. The error amplifier has one input portion connected to the output terminal, the other input portion and an output portion. The error amplifier outputs the control potential via the output portion to make the resistance of the power switch section high so that potential applied to the one input portion is high to potential applied to the other input portion. The wiring connects a reference terminal to the other input potion. In addition, the reset switch section is configured to isolate the wiring from a baseline potential when the input terminal is supplied with a potential, and to connect the wiring to the baseline potential when the input terminal is not supplied with the potential.
    • 根据一个实施例,电源电路包括电源开关部分,误差放大器,布线和复位开关部分。 误差放大器具有连接到输出端子,另一个输入部分和输出部分的一个输入部分。 误差放大器通过输出部分输出控制电位,使电源开关部分的电阻变高,使得施加到一个输入部分的电位高到施加到另一个输入部分的电位。 接线将参考端子连接到另一个输入部分。 此外,复位开关部分被配置为当输入端被提供电位时将布线与基线电位隔离,并且当输入端未被提供电位时,将布线连接到基准电位。
