Embodiment Construction

[0039] The technical content of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] The invention provides a CT scanning visual positioning method, which automatically locates the scanning start position and the scanning end position of the CT scanning based on the visual positioning technology and anthropometry knowledge during the moving process of the scanning bed. The above-mentioned CT scanning visual positioning method can use the visual recognition method to automatically locate the part of the human body to be scanned before the CT scanning, which can prevent the human body from being exposed to additional X-ray radiation and reduce the workload of medical staff.

[0041] Such as figure 1 As shown, the above-mentioned CT scanning visual positioning method includes the following steps: (1) setting the scanning position, scanning parameters and patient's human body parameters; (2) obtainin...

Abstract

The invention discloses a CT scanning visual localization method, which comprises the following steps: (1) setting a scanned site, scanning parameters and human body parameters of a patient; (2) acquiring one or more localization reference human body characteristics related to the scanned site; (3) in a process of moving a scanning bed, continuously acquiring human body images passing a scanning region and implementing human body characteristic recognition in real time, and acquiring positions, corresponding the localization reference human body characteristics, of the scanning bed; and (4) inaccordance with the acquired scanning bed positions, in combination with anthropometry knowledge, calculating an initial scanning position and an ending scanning position, corresponding to the scanned site, of the scanning bed. According to the CT scanning visual localization method, automatic localization can be implemented in a moving process of the scanning bed in accordance with the selectedscanned site, so that a relatively high processing speed and accurate localization are guaranteed, and the method is friendly to the patient. Meanwhile, the invention also discloses a CT system for implementing the CT scanning visual localization method.

Description

technical field [0001] The invention relates to a CT scanning visual positioning method, and at the same time relates to a CT system for realizing the above positioning method, belonging to the technical field of computer tomography. Background technique [0002] Computed Tomography (abbreviated as CT) is currently the mainstream medical imaging inspection equipment in the world, and it has been widely promoted in various countries. [0003] CT imaging mainly relies on X-rays. When X-rays are shot at human tissues, part of the rays will be absorbed by the human body, and part will pass through the human body and be received by the detector. Different tissues in the human body have different densities and different X-ray penetration capabilities, so the X-rays received by the detector will also be different. Using this principle, CT can show humans the internal tissues of the human body and help humans discover some abnormalities and defects in the human body. Because X-ray...
