Embodiment Construction

[0041] In order to describe the above-mentioned technical solution of Fang Ming in more detail, the following inventors list specific implementation examples to illustrate the technical effect. It should be emphasized that these implementation examples are only used to illustrate the present invention and not limit the scope of the present invention.

[0042] Embodiment Use Micro-CT imaging system to carry out scan reconstruction to juvenile mouse

[0043] The juvenile mouse is a juvenile mouse with a length of about 100 mm and a diameter of about 30 mm. The scanning and reconstruction method is shown in the system flow chart, and the specific implementation steps are as follows:

[0044] 1. First reset the stage. That is, the rotation axis is close to the X-ray detector in the horizontal direction, and is located at the coordinate origin in the vertical direction. Set the frame rate of the panel to 0.5frame / s, set the size of the collected image to 1000×1000, turn on the X-...

Abstract

The invention discloses a method for carrying out scanning reconstruction on a long target object by using a Micro-CT imaging system. The method is characterized by comprising the following steps of: (1) beginning to prescan from an initial position of an object to a final position thereof to obtain a projected image of the whole object; (2) selecting an interested region as a scanning frame of a reconstruction range region from the projected image of the object, segmenting the scanning frame, and calculating corresponding segmented actual position information of the projected image from the segmented reconstruction region; and (3) adjusting the position of an object table to the upmost segment of the segmented reconstruction region of the object to be acquired, scanning each segment in sequence, carrying out reconstruction on each segment, splicing the segmented reconstruction sequences, and finally obtaining a tomograph of the long target object. A great deal of scanning reconstructions prove that the method is effective to the scanning reconstruction of the long target object, effectively solves the defect that the long target object can not carry out the scanning reconstruction completely, is stable and reliable, and has great using prospect.

Description

technical field [0001] The invention belongs to the technical field of micro-X-ray imaging, and in particular relates to a Micro-CT imaging system capable of scanning and reconstructing long target objects and a scanning and reconstruction method thereof. Background technique [0002] 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 to obtain information, and obtained 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 field of radiological diagnosis. At present, this technology has been widely used in various fields, such as medicine, industry and mate...
