Injection dose selection mechanism

Abstract

The invention relates to an injection dose selection mechanism, which comprises an auxiliary electronic assembly, located in a gamma-ray CT machine and comprising a camera, an optical disc memory, a work station, a display screen and a developing machine; a live scanning assembly, used for performing live gamma-ray scanning operation on a diseased portion of a patient to be examined and acquiringcorresponding gamma-ray images, wherein the camera is used for photographing the gamma-ray images output by the live scanning assembly to acquire CT electronic images, and the developing machine is connected with the camera and is used for receiving the CT electronic images and developing the CT electronic images into a CT film, and the live scanning assembly is further connected with the opticaldisk memory, the work station and the display screen; an auxiliary angiography apparatus, used for extracting a corresponding dose of a contrast medium from a contrast medium storage container according to a received reference injection dose; and dose selection equipment, used for determining the corresponding reference injection dose according to a received age. Due to the injection dose selection mechanism, the injection dose of the contrast medium can be automatically selected.

Description

technical field [0001] The invention relates to the field of gamma-ray CT machines, in particular to an injection dose selection mechanism. Background technique [0002] The new nuclei produced by γ-ray CT machine after α-decay and β-decay of radioactive nuclei are often at a high energy level, and they need to transition to a low energy level to radiate γ photons. Both nuclear decay and nuclear reactions can produce gamma rays. It is an electromagnetic wave with a wavelength shorter than 0.2 Angstroms. The wavelength of γ-rays is shorter than that of X-rays, so γ-rays have a stronger penetrating ability than X-rays. [0003] Gamma rays have no electric charge and static mass, so they have a weaker ionization ability than alpha particles and beta particles. Gamma rays are extremely penetrating and have high energy.

Problems solved by technology

[0004] In order to solve the technical problem that the current dose of gamma-ray CT machines cannot be accurately controlled when radiography is required, the present invention provides an injection dose selection mechanism, which introduces a shape resolution device, which is used to perform shape resolution on human objects in the image to determine the resolution. age group, a dose selection device is also introduced to determine the corresponding reference injection dose based on the received age group; in specific image processing, zigzag-based traversal is performed in the image to be processed, which is used to traverse the zigzag Each image area obtained is used as each target processing area, and the representative redundancy of the image to be processed is determined based on each image redundancy of each target processing area, and when the representative redundancy exceeds the limit, channel enhancement is introduced Device for custom data augmentation
