Description

Technical Field

[0001] The invention discloses an imaging device for an X-ray detection film used for thermally excited luminescent imaging, belongs to the technical field of optical imaging, and specifically relates to a real-time imaging device for a thermally activated X-ray detection film. Background Art

[0002] Digital X-ray detectors can convert X-rays that are invisible to the naked eye into digital signals for imaging. They replace traditional X-ray films. After being irradiated with X-rays, they generate electrical signals proportional to the radiation intensity, forming latent images in fluorescent materials. The X-ray detector with latent images is scanned and read with laser excitation to obtain digital images. With the advantages of reusability, better linearity than film, and short exposure time, X-ray imaging technologies such as CR and CT that use X-ray detectors to collect images have developed rapidly. In the past few decades, flat-panel X-ray detectors based on photoelectric conversion of X-rays or indirect conversion by using scintillating materials have been realized, but they need to be scanned in time after taking pictures, otherwise the image will gradually fade. The "X-ray Detection Film-Manufacturing Method and Its Use" proposed by Application No. 2020104150130 overcomes this difficulty and provides an X-ray detection film with long-term stability and applicable to any curved surface or irregular shape. The X-ray image captured by it can be obtained within 15 days. Unlike traditional X-ray detectors, after the flexible X-ray detection film forms X-ray imaging memory, it needs to be removed and spread out for heating. Under thermal excitation, the heat releases the trapped electrons, and the electrons in the fluorescence center will return to their initial energy level and generate visible light emission, and the camera can capture the image of the visible light emission. The whole process is very cumbersome and step-by-step.

[0003] It is hoped to provide a heating imaging device suitable for this type of heat-activated flexible X-ray detection film, which can directly take images after uniformly heating this type of heat-activated flexible X-ray detection film. Summary of the invention
