Microscopy CT imaging device with three-free degree motion control and correcting method thereof

Abstract

The invention provides a microscopy CT imaging device with three-free degree motion control and a correcting method thereof. The microscopy CT imaging device comprises an X-ray source (1) and an X-ray source detector (2), wherein a material-carrying table (3) is arranged between the X-ray source (1) and the X-ray source detector (2). The device is characterized in that the material-carrying table is externally provided with a driving device for driving the material-carrying table to move along the horizontal direction, the vertical direction and the rotation direction. The device solves the problems of serious shake, large error and low precision when the common microscopy CT mechanical device moves; leads the three-free degree direction motion to be more stable, the speed to be more even, and the precision degree to be higher; has better radiation shield effect; solves the problem of the heat dissipation of the X-ray source and the X-ray source detector; solves the problem that the X-ray source, the X-ray source detector and a material-rotating center are positioned at one line; and lays good foundations for the subsequent image acquisition and image reconstruction.

Description

technical field [0001] The invention belongs to the technical field of micro-X-ray computed tomography imaging, in particular to a three-degree-of-freedom control system of micro-CT imaging equipment. Background technique [0002] X-ray computed tomography (x-ray computedtomography, x-ray CT or CT) appeared in the 1970s, which is the product of the combination of modern computer technology and X-ray inspection technology. In 1971, British EMI company Hounsfield successfully developed the first head CT scanner. In 1975, the first full-body CT machine designed by Ledkey in the United States came out. It used X-ray beams to scan the human body, obtain information, and obtain reconstructed images through computer processing. , thereby significantly expanding the scope of human body inspection, improving the detection rate of lesions and the accuracy of diagnosis. This diagnostic method with high diagnostic value, no pain, no trauma, and no danger is a major breakthrough in the ...
