Embodiment Construction

[0066] figure 1 An example of the configuration of a radiographic system for illustrating an illustrative embodiment of the present invention is shown, and figure 2 show figure 1 Control block diagram of the radiography system.

[0067] Meanwhile, the same configurations as those already described are denoted by the same reference numerals, and descriptions thereof are omitted. Differences from the already described configuration will be described.

[0068] The X-ray imaging system 10 is an X-ray diagnostic apparatus that performs imaging while a subject (patient) H is standing, and includes: an X-ray source 11 that irradiates the subject H; an imaging unit 12 that Used as a radiographic image detection device that is opposed to the X-ray source 11, wherein the subject H is interposed between the X-ray source 11 and the imaging unit, and that detects the transmitted light from the X-ray source 11 through the X-rays of the subject H, and thereby generate image data; and th...

Abstract

The invention discloses a radiological image detection apparatus, a radiographic apparatus and a radiographic system. The radiological image detection apparatus includes a first grating unit, a grating pattern unit, a radiological image detector, and an anti-scatter grating. The grating pattern unit has a period that substantially coincides with a pattern period of a radiological image formed by radiation having passed through the first grating unit. The radiological image detector detects the radiological image masked by the grating pattern unit. The anti-scatter grating is arranged on a path of the radiation incident onto the radiological image detector and removes scattered radiation. A smoothing process is performed for at least one of a surface and a backside of the anti-scatter grating intersecting with a traveling direction of the radiation.

Description

technical field [0001] The present invention relates to a radiographic image detection apparatus, a radiographic apparatus, and a radiographic system capable of enabling phase contrast imaging of a subject by using radiation such as X-rays. Background technique [0002] Since X-rays are attenuated according to the atomic number of elements constituting a material and the density and thickness of the material, X-rays are used as a probe for seeing through the inside of a subject. Imaging using X-rays is widely used in fields such as medical diagnosis and nondestructive testing. [0003] In a general X-ray imaging system, a subject is arranged between an X-ray source that irradiates X-rays and an X-ray image detector that detects the X-rays, and a transmission image of the subject is captured. In this case, the X-rays irradiated from the X-ray source to the X-ray image detector undergo attenuation (absorption ), and then incident on each pixel of the X-ray image detector. A...
