Abstract

The invention provides a CT based (Computerized Tomography) wide-breadth dynamic three-dimensional human body scanning system. The CT based wide-breadth dynamic three-dimensional human body scanning system comprises a near-infrared transmitter, a near-infrared receiver, a color camera and a PC (Personal Computer) end; the near-infrared transmitter is used for transmitting light covering human body surfaces; the near-infrared receiver is used for collecting light reflected by a human body; the color camera is used for collecting color image data of the human body; the PC end constructs a three-dimensional profile of the human body through simultaneously collected color data and depth data according to the receiving time difference of different light of the near-infrared receiver; the PC end constructs a positioning image according to an obtained three-dimensional human body surface patch image; the PC end confirms a CT scanning region according to the positioning image and controlling the radiation dosage during CT scanning according to a transverse image of the three-dimensional human body surface patch image. The CT based wide-breadth dynamic three-dimensional human body scanning system can well construct a starting position and a terminal position of scanning and controls the radiation dosage at different positions according to the section of the three-dimensional human body profile.

Description

technical field [0001] The invention relates to the field of CT technology, in particular to a CT-based wide-format dynamic three-dimensional human body scanning system. 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 system cannot fundamentally solve the problem, nor can i...
