Abstract

The invention relates to the technical field of X-ray imaging, in particular to a micro-focusing in-line phase-contrast imaging automatic system with X-ray sources. The micro-focusing in-line phase-contrast imaging automatic system comprises a rotary platform. A sample stage is arranged in the middle of the rotary platform, and more than two micro-focus light source assemblies are arranged on the outer side of the sample stage; the micro-focus light source assemblies are mounted on the rotary platforms; an annular detector is arranged on the outer side of the rotary platform, an image transmitter is connected onto the detector, and image data can be transmitted onto a master controller by the image transmitter; the master controller is used for controlling the rotary platform and the micro-focus light source assemblies and transmitting the received image data into a control terminal; the control terminal is connected with the master controller and is used for transmitting control instructions to the master controller and analyzing and reconstructing the received image data to obtain CT (computerized tomography) images. The micro-focusing in-line phase-contrast imaging automatic system has the advantages that the micro-focusing in-line phase-contrast imaging automatic system is high in scanning imaging speed and can bring convenience for accommodating samples and adjusting the intensity of the X-ray sources and the distances from the X-ray sources to the samples, and accordingly the experiment efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to a coaxial phase-contrast imaging automation system based on a micro-focus X light source. Background technique [0002] Since 1896, X-rays have been used in medical imaging; after more than 100 years of development, X-ray technology has become very mature and has become a routine inspection and treatment method in hospitals. [0003] X-rays are used in medical diagnosis, mainly based on the penetration, differential absorption, photosensitivity and fluorescence of X-rays. When X-rays pass through the human body, they are absorbed in different degrees. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles, so the amount of X-rays after passing through the human body is different, which will carry the density distribution of various parts of the human body. There is a big difference in the strength of the fluorescent effect or photosens...
