Synchronous radiation based real-time X-ray three-dimensional imaging system and imaging method

Abstract

The invention relates to a synchronous radiation based real-time X-ray three-dimensional imaging system and imaging method. The system comprises a synchronous radiation X-ray source, optical cables, two capillary tube devices, a sample table, an X-ray imaging detector and a data processing device, wherein the optical cables are arranged at output ends of the synchronous radiation X-ray source and are provided with two light through holes, the capillary tube devices are separately arranged at the two light through holes of the optical cables, the sample table is arranged at a position where two light beams are intersected through the capillary tube devices and is used for placing a sample, the X-ray imaging detector is arranged on one side of the sample table, and the data processing device is connected with the X-ray imaging detector. Compared with a traditional X-ray computer tomography (CT) technique, the system has the advantages that the imaging time resolution is greatly increased, real-time imaging can be achieved, and the radiated dosage of the sample is reduced.

Description

technical field [0001] The invention relates to an X-ray imaging system and method, in particular to a real-time X-ray stereoscopic imaging system and imaging method based on synchrotron radiation. Background technique [0002] In visible light, binocular stereo vision technology has been greatly developed in recent years. It is based on the principle of parallax. Two digital images of the same object are simultaneously acquired by dual cameras from different angles, and the three-dimensional geometric information of the object is restored. With the rapid development of binocular stereo vision technology in the past two decades, it has been gradually improved and applied to many fields such as robot visual navigation, aerial surveying and mapping, medical imaging and industrial inspection. [0003] The X-ray imaging technology based on synchrotron radiation is generally divided into two categories, namely two-dimensional X-ray radiography and three-dimensional X-ray CT techn...

AI Technical Summary

Problems solved by technology

However, since the three-dimensional X-ray CT technology requires a large number of rotating projections on the sample, it will greatly increase the imaging time and the irradiation dose of the sample. Therefore, it is impossible or difficult to perform real-time observation experiments, especially real-time imaging of living biological samples. , has great limitations
