Abstract

The invention provides a positioning plate imaging method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a plurality of projection images of a plurality of different parts of a scanned object; performing shimming correction on each projection image in the plurality of projection images to obtain a plurality of shimming images; and obtaining a positioning plate image based on the shimming images. According to the invention, the shimming correction is carried out on each projection image in the plurality of projection images to obtain the plurality of shimming images, the image contrast and definition of the shimming images are improved, the positioning plate image is obtained based on the plurality of shimming images with higher image contrast and definition, and the contrast and definition of the positioning plate image can be improved.

Description

technical field [0001] The invention relates to the field of CT imaging, in particular to a positioning film imaging method, device, electronic equipment and storage medium. Background technique [0002] Micro computed tomography (Micro Computed Tomography, Micro CT), also known as micro CT, micro CT, is a non-destructive 3D imaging technology, which can clearly understand the internal microstructure of the sample without destroying the sample. , with a very high resolution. Before the tomographic scan of Micro CT, a positioning slice scan will be performed to obtain the positioning slice image, and the scan information such as the position, angle, and layer thickness to be scanned can be determined through the positioning slice image. [0003] The scan image is often a complete image of the entire scanned object, but the length of the scanned object usually exceeds the coverage of the detector. Therefore, in the prior art, the scan of a long object by Micro CT is usually d...
