Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
In the prior art, X-rays belong to high-energy rays and have certain penetrability to objects. Different materials. Different densities. The X-ray transmission capability will vary for substances of different thickness (i.e. the degree of attenuation will vary as the radiation is transmitted). After a beam of X-rays passes through the object under inspection. The intensity of each point of the beam of rays is inconsistent, but has positive correlation with the density of tissue in the object to be measured. If the detection result is to be known, the ray needs to be changed into a visible shadow.
Because of the high X-ray frequency and short wavelength (frequency band range 10 to 12 Hz). Obviously, the radiation in this frequency band is invisible to the human eye, and in order to see the detection result, the invisible radiation and image must be converted into a visible image.
The utility model provides a novel X-ray detection pattern imager.
Example 1:
as shown in fig. 1, the novel X-ray detection pattern imager includes a cylindrical housing 1, a low-illuminance camera 2, and a fluorescent conversion plate 3.

The low-illuminance camera 2 is a low-illuminance CCD camera, the low-illuminance camera 2 is mounted inside the cylindrical housing 1, and the low-illuminance camera 2 is fixed at the closed end of the cylindrical housing 1, with the lens of the low-illuminance camera 2 being disposed toward the opening of the cylindrical housing 1. The fluorescent conversion plate 3 is fixedly mounted at the open end of the cylindrical housing 1.
The fluorescent conversion plate 3 is used for converting rays into visible light, and when the X-rays pass through the fluorescent conversion plate 3, the X-rays are excited and generate visible light, and the stronger the X-rays are, the stronger the generated visible light is, and conversely, the weaker the generated visible light is. The fluorescent conversion plate 3 of a certain thickness can absorb all X-rays and convert them substantially into visible light, i.e. a higher conversion efficiency is produced. The fluorescent conversion plate 3 and the cylindrical shell 1 form a full-closed structure to isolate external visible light rays and form an internal cassette so as to improve the conversion effect of the fluorescent conversion plate 3.
After the X-ray beam passes through the object to be measured, the intensity of each point is different when the ray reaches the fluorescent conversion plate 3 due to the different internal tissues, and the visible light points with different intensities of each point are formed through fluorescent conversion, so that the black-and-white patterns of the visible light inside the object to be measured are formed due to the inconsistent intensity and gray scale of each point, and the black-and-white patterns are shot and recorded by the low-illumination camera 2 to become video signals.
