Description

Dental X-ray Image Output Device {Dental Xray Video Output Device}

The present invention relates to a dental X-ray image output device, and more particularly, by using a high-sensitivity image plate called an IP (Imaging Plate) to store a latent image, and then inserting the image plate into the image acquisition unit to obtain an image from the latent image of the image plate. It relates to a dental X-ray image output device that acquires a signal, converts the acquired image signal into a digital signal, and interworks with external equipment.

In general, an X-ray image is obtained by developing an X-ray-injected film. In the case of acquiring an X-ray image using a film, a film, a developer, a developer, and a film storage place are additionally required in addition to the X-ray equipment. And if the shooting is wrong, the above additional stuffs are additionally required for re-shooting. In addition, since it takes a certain amount of time to develop the film after X-ray imaging, the user cannot immediately check the captured image.

In order to compensate for these problems, recently, computed radiography (CR) has been widely used in the market. A radiographic imaging apparatus acquires a digitized X-ray image by irradiating an X-ray to an imaging plate instead of a film, and scanning a latent image accumulated on the image plate with a laser beam.

In other words, when X-rays are irradiated to the image plate, a latent image having energy proportional to the amount of X-ray irradiation exists on the image plate. When a laser of a red wavelength band is scanned on the image plate, a latent image is expressed in a blue wavelength band, and a digital X-ray image is obtained by scanning the developed image. The image plate is then reused for subsequent imaging by exposing the image plate to strong light to remove residual latent images.

However, conventional dental X-ray image output devices expose the image plate by tearing the sanitary cloth with the image plate embedded therein for scanning the image of the image plate in which the latent image is stored after being exposed to X-rays, and then manually push it into the scanner insertion hole, or insert the built-in tray. After sliding out, the image plate is placed in a predetermined position and the tray is pushed in to scan the image. At this time, only one image plate is inserted into the scanner insertion hole or tray, When it is necessary to acquire a digitized X-ray image, it takes a lot of work time and has a problem in that the lifespan is shortened because the number of driving times of the output device for acquiring the X-ray image increases.
