Technical Field

[0001] The invention relates to the technical field of medical image scanning and positioning, and more specifically to a fast scanning and positioning device for medical imaging equipment. Background Art

[0002] Medical imaging refers to the technology and process of obtaining images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. When scanning the head or body of a patient, the patient's head and body edges can be positioned in combination with a positioning device, which prevents inaccurate image generation and errors in the position of the scanning center point caused by the shaking of the human body's autonomous reaction. Therefore, the scanning accuracy of medical images can be improved with the cooperation of the positioning device; In summary, the inventors have discovered that the existing positioning devices mainly have the following defects: since the current positioning devices are divided into two forms: head positioning and body positioning, when patients need to undergo simultaneous head and body image scanning, they need to move to the corresponding equipment for positioning scanning. Therefore, the current positioning devices cannot combine the two positioning structures of the head and body into one for use, which will cause inconvenience to patients when scanning their head and body and reduce the efficiency of scanning positioning.
