The present application relates to the technical field of micro computer tomography, and discloses a large-aperture parabolic single glass tube micro-CT system and a reconstruction method thereof, the system comprising an X-ray source, a straight-through X-ray shutter, a first lens supported by a lens support to move, a sample supported by a sample stage and an X-ray flat panel detector arranged in sequence along an optical axis; the first lens is a large-aperture parabolic glass tube lens of millimeter level, and the lens support is used for adjusting the angle, pitch and optical axis coaxiality of the first lens; an electric control platform controller is electrically connected with the lens support and the sample stage respectively, and a main control computer controls the sample stage to perform angle scanning, sub-pixel angle jitter sampling and multi-view field splicing scanning through the electric control platform controller. The present application adopts a large-aperture parabolic glass tube lens of millimeter level, and the quasi-parallel beam geometry after system regulation and control enables the micro-CT system to be compatible with parallel beam algorithm, and the image reconstruction quality of the original cone beam algorithm is retained and improved.
