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.
