Abstract

The embodiment of the present invention discloses an imaging scanning automatic positioning method, device, equipment and medium, the method comprising: acquiring a positioning image of an object; determining the position information of at least one target structure according to the positioning image; based on the The location information of the target structure determines the scanning protocol corresponding to the target structure. The method provided by the embodiment of the present invention automatically determines the location information of the target structure by identifying the positioning image, and plans the scanning protocol based on the location information of each target structure, so as to realize accurate and fast automatic positioning of imaging and scanning, and make the scanning The method is more reasonable and the imaging effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical imaging, and in particular to an imaging scanning automatic positioning method, device, equipment and 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. In order to optimize the image quality and scanning time of whole-body scanning, no scanning scheme is usually adopted for different beds. In the prior art, when scanning the subject, the doctor generally determines the acquisition range of the whole body or a specific part from the simple whole body structure diagram of the pre-scan, and then manually plans the number of beds to be scanned according to the pre-scan structure diagram, and adjusts the number of beds for each bed. Acquisition range...
