Embodiment 1

[0098] figure 1 It is a functional block diagram showing the structure of the X-ray phase difference imaging device according to the present invention. Such as figure 1 As shown, the X-ray source 3 according to the present invention is configured to include an anode 3a to which electrons collide, and a multi-slit 3b for incident X-rays emitted from the anode 3a, for irradiating X-rays. The anode 3a is a target of electrons, and X-rays are generated when high-speed electrons collide with the anode 3a. X-rays are generated at a single focal point. The X-ray source 3 irradiates X-rays. The X-ray source 3 is configured for the purpose of outputting X-rays of a specific wavelength. The subject M is placed between the phase grating 5 and the FPD 4. In addition, you can also Figure 36 As shown, it is assumed that the subject M is placed between the multi-slit 3 b and the phase grating 5. The X-ray source 3 corresponds to the radiation source of the present invention. The FPD 4 ...

Abstract

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 radiationimaging 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 moire-like image of the phase grating 5 is observed. Since the long-period moire-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 aminute 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.

Description

Technical field [0001] The present invention relates to a radiographic apparatus capable of imaging the internal structure of an object by using radiation passing through the object. Background technique [0002] Conventionally, various devices have been conceived as radiographic apparatuses that allow radiation to pass through an object to image the internal structure of the object. A general example of such a radiographic apparatus is a radiographic apparatus that irradiates an object with radiation, and shoots a projection image of the radiation by passing the radiation through the object. In such a projection image, shades are expressed in accordance with the ease of passing radiation, and the shades represent the internal structure of the object. [0003] In such a radiographic apparatus, only objects having a property of absorbing radiation to some extent can be imaged. For example, biological soft tissues hardly absorb radiation. Even if this kind of tissue is photographe...
