Description

Xray Video Output Device}

The present invention relates to an X-ray image output device, and more particularly, after storing a latent image using a high-sensitivity image plate called an IP (Imaging Plate), the image plate is inserted into an image acquisition device to obtain an image signal from the latent image of the image plate. The present invention relates to an X-ray image output device that acquires and converts the acquired image signal into a digital signal to interlock with external equipment.

In general, an X-ray image is obtained by developing an X-ray-scanned film. When an X-ray image is acquired using a film, in addition to the X-ray equipment, a film, a developer, a developer, and a film storage place are additionally required. And if the shooting is wrong, the above additional stuffs are additionally required for re-shooting. In addition, since it takes a certain time to develop the film after taking the X-ray, 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. The radiographic imaging apparatus obtains a digitized X-ray image by irradiating an X-ray onto an imaging plate instead of a film and scanning the latent image accumulated on the image plate with a laser beam.

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

However, in the conventional computer radiator, after exposing the image plate to X-rays, there is the hassle of detaching the cassette with the image plate and moving it to a separate scanner for image scanning, and continuous shooting is impossible due to frequent mounting and detachment of the cassette.
