Embodiment 1

[0041] refer to figure 2, The present invention provides a self-shielding vertical CT scanner. The CT scanner comprises an outer casing 20, an outer shield door 21 arranged on the outer casing 20, a vertical lifting mechanism 30 arranged on the inner wall of the outer casing 20, and a horizontal rotation mechanism arranged on the vertical lifting mechanism 30 40. The horizontal rotation mechanism 40 is provided with an X-ray scanning mechanism 50 for scanning and detecting the human body 80 inside the inner casing 60 . A shielding layer is provided outside the outer shell 20 to shield the X-rays emitted by the X-ray scanning mechanism 50 .

[0042] Such as figure 2 As shown, the outer casing 20 of the present invention adopts a cylindrical structure. A shielding layer 22 for shielding X-rays is pasted on the outer side of the outer casing 20 . The thickness of the shielding layer 22 can be determined according to the radiation dose required outside the scanner and the s...

Embodiment 2

[0061] Such as Figure 8 As shown, the external shield door 21 is connected to the external housing 20 in a rotational manner. The rotary external shield door 21 can be designed on the outside or inside of the external casing 20 . When the outer shielding door 21 is closed, both sides of the outer shielding door 21 partially overlap with the shielding layer 22 of the outer shell 20 to ensure the continuity and completeness of radiation shielding. Such as Figure 9 As shown, when the rotatable external shield door 21 rotates outward with one side of the door as the rotating shaft, a channel is opened on the front of the external housing 20, and personnel can enter and exit the scanner. The inner door 61 and the inner housing 60 may also be connected in a rotational manner, and the vertical edge of the inner door 61 is used as a vertical axis to open inward. Other structures are with embodiment 1.

Abstract

The invention provides a self-shielding vertical CT scanner, and relates to the technical field of medical instruments. The self-shielding vertical CT scanner comprises an outer shell, an outer shielding door arranged on the outer shell, a vertical lifting mechanism arranged on the inner side of the outer shell and a horizontal rotating mechanism arranged on the vertical lifting mechanism. An X-ray scanning mechanism is arranged on the horizontal rotating mechanism and is used for scanning and detecting a human body in the inner shell; and a shielding layer is arranged outside the outer shell so as to shield X-rays of the X-ray scanning mechanism and prevent the X-rays from causing radioactive radiation to the outside of the scanning mechanism. The outer shell adopts a self-shielding design, so that the problem of radioactive radiation of the X-rays to the outside of the scanning mechanism can be solved; and the vertical design is adopted, so that the CT scanner occupies a smaller space and is more suitable for the self-shielding design of radioactive radiation, and the cost of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a self-shielding vertical CT scanner. Background technique [0002] X-Ray CT (Computed Tomography), that is, X-ray computerized tomography, is a medical imaging method that uses the degree of X-ray absorption by human tissue when irradiating the human body to calculate the shape of human tissue. X-rays are generated by hitting a metal target with accelerated electrons. During impact, the electrons slow down and release their kinetic energy in the form of photons, forming a continuum of X-ray spectra. In addition, when the energy of the electron beam is large enough, the inner electrons of the metal atoms may be knocked out. At this time, electrons in the outer layer of the atom jump back to the inner layer to fill the hole in the inner layer, and at the same time release photons with a wavelength of about 0.1 nanometers, forming the characteristic line in the X-ray ...
