Embodiment Construction

[0060] figure 1 An example of the configuration of a radiographic system for illustrating an illustrative embodiment of the present invention is shown, figure 2 yes figure 1 Stereoscopic view of the radiography system, and image 3 yes figure 1 Control block diagram of the radiography system.

[0061] The X-ray imaging system 70 is an X-ray diagnostic apparatus that performs imaging of a subject (patient) H while the patient is standing, and includes an X-ray source 11, an imaging unit 12, and a console 13, and the X-ray source 11 irradiates and photographs with X-rays. Object H; imaging unit 12 is opposed to X-ray source 11, detects X-rays penetrating photographed object H from X-ray source 11, and thereby generates image data; console 13 controls exposure of X-ray source 11 based on operator's operation Operation and Imaging operation of the imaging unit 12, image data acquired by the imaging unit 12 is calculated, and thus a phase contrast image is generated.

Abstract

A radiographic apparatus includes a radiation source that irradiates radiation, a first grating unit, a grating pattern unit, a radiological image detector, and a support unit. The radiation irradiated from the radiation source passes through the first grating unit. The grating pattern unit includes a periodic form that has a period which substantially coincides with a pattern period of a radiological image formed by the radiation having passed through the first grating unit. The radiological image detector detects a masked radiological image which is formed by masking the radiological image by the grating pattern unit. The support unit supports the radiation source, the first grating unit, the grating pattern unit and the radiological image detector. The radiation source is attached to the support unit via a vibration-proof member.

Description

technical field [0001] The present invention relates to a radiographic apparatus and a radiographic system. Background technique [0002] Since X-rays are attenuated according to the number of atoms of elements constituting the material and the density and thickness of the material, X-rays are used as probes for seeing through the inside of a subject to be diagnosed. X-ray imaging is widely used in fields such as medical diagnosis and non-destructive testing. [0003] In a general X-ray imaging system, an object to be diagnosed is arranged between an X-ray source that irradiates X-rays and an X-ray image detector that detects X-rays, and a transmission image of the object to be diagnosed is captured. In this case, the X-rays irradiated from the X-ray source to the X-ray image detector undergo quantity attenuation (absorption ), and then incident on each pixel of the X-ray image detector. As a result, the X-ray image detector detects and captures the X-ray absorption image...
