Abstract

The invention provides a wide-breadth dynamic human body rapid scanning method, which comprises the following steps: 1, installing a CMOS (complementary metal-oxide-semiconductor transistor) camera; 2, rapidly shooting images and transmitting the images to a background PC (personal computer) machine in real time; 3 conducting intelligent human outline recognition, acquiring a human body image by virtue of the CMOS camera in real time and recognizing a human body region; 4, conducting intelligent recognition on the human body region and dividing the region into different regions corresponding to various parts of a human body; 5, by conducting size calibration and position calibration on a system, providing thickness sections at an equal proportion; 6, by conducting recognition, obtaining initial positions and sizes of the various parts of the human body, and providing diagonal coordinate values; 7, by acquiring location data of the various parts of the human body, designing a set of alarm system, and adopting various alarm modes in accordance with different security levels; and 8, selecting segmentation and detection modes in accordance with clothing in a detected object. With the application of the scanning method disclosed by the invention, a location image can be effectively acquired, without causing residual radiation influence on the human body.

Description

technical field [0001] The invention relates to the technical field of medical image-assisted positioning, in particular to a method for fast scanning of a wide-format dynamic human body. Background technique [0002] In the current conventional spiral CT examination, it is necessary to scan the positioning image first, and then determine the starting point and the ending point of the scan on the positioning image to determine the scanning range. Conventional dose positioning scanning not only increases the radiation dose of the patient, but also shortens the life of the tube. If the positioning image is not scanned, the scanning range cannot be accurately determined. [0003] Current research focuses on doctors shortening the scanning path of positioning images based on their own clinical experience, thereby reducing the patient's exposure dose, reducing exposure time, and prolonging the life of the CT tube. This artificial experience method cannot fundamentally solve the ...
