Imaging scanning protocol automatic planning method, device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses an imaging scanning protocol automatic planning method, device, electronic equipment and storage medium. The method includes: acquiring a first image and a second image, the first image includes preset features of the scanned object, and the second image includes structural information of the scanned object structure; determining the The feature information of the feature is preset, and the structure information of the target structure is determined according to the second image; and the scanning protocol for imaging and scanning the scanning object is determined according to the feature information and the structure information. Through the above technical solution, the automatic, rapid and accurate formulation of the imaging scanning protocol is realized, the scanning method is more reasonable, and the imaging effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technology, and in particular to an imaging scan protocol automatic planning method, device, electronic equipment and storage medium. Background technique [0002] At present, when collecting signals of the whole body or half of the body, due to the limitation of the detector in the longitudinal range, it is necessary to collect signals in multiple beds, and then reconstruct and stitch them into the required images. Therefore, before fine-scanning the scanning object, it is necessary to determine the scanning protocol including the number of beds to be scanned and the positions of each bed, as well as the scanning range and scanning parameters of each bed. [0003] In the prior art, the planning of the scanning protocol for the scanned object is manually planned by the technician according to the simple structural structure diagram (including the overall outline and landmark struct...

Problems solved by technology

The reason for this planning is that, on the one hand, based on the characteristics of the detector, the imaging effect in the central area of ​​the scanning range is better; The change of the relative position of the bed image will cause image misalignment and inaccuracy during image stitching

[0004] The problems in the above schemes are as follows: First, manual imaging and scanning protocols need to be formulated, which is not only time-consuming and labor-intensive, but also increases the burden on technicians, and the structural position estimated artificially from the pre-scanned simple whole-body structure map may be inaccurate, resulting in Unreasonable scan planning affects the final imaging effect

Second, the distribution of personalized features inside the scanned object is unique and uncertain. If the scanning protocol is planned only based on the structural information of the scanned object, it may not be possible to locate the personalized features at the center of the scanning range, and thus the individuality cannot be obtained. High-quality images of personalized features, or additional scanning to obtain high-quality images of personalized features, increasing scanning time

For example, see figure 1 , the personalized features 100 in each scanned object are distributed in a wide range, and the scanning protocol planned only based on the structural structure information cannot make the personalized features of each scanned object be in the center of the scanning range

If the technician finds that the personalized feature is in the overlapping area of ​​the scanning range of the two beds after the fine scan, then after the fine scan, the technician will often scan the area where the personalized feature is located, which will undoubtedly prolong the scanning time
