Description

Bucky for x-ray imaging apparatus [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bucky for an X-ray imaging device, and more particularly to a bucky for an X-ray imaging device capable of rotating and moving a cassette.

Generally, an X-ray imaging apparatus refers to an apparatus that irradiates an X-ray to a target and detects a difference in energy intensity distribution of the transmitted X-rays, and there are an analog system and a digital system as detection means.

In the analog system, a silver halide film is combined with a sensitizing paper (fluorescent plate) that emits light when an X-ray is received, a latent image is formed on a silver halide film with light generated from a sensitizing dye, and the silver halide film is chemically treated to obtain a visible image. For this purpose, there is a film cassette which is used to store the sensitizing paper and the silver salt film in a dark state and to shoot them.

The digital system is a detection medium responsive to an X-ray and has a two-dimensional sensor. The microelectronic signal generated in the sensor is obtained through a two-dimensional matrix and amplified by an amplification circuit. The amplified signal is converted into a digital value And then displays the image data on a monitor or a printer through an appropriate image processing process.

The X-ray detector used in the digital system includes a CR (Computer Radiography) using an image plate, a CCD detector using a scintillator and a charge-coupled device, a thin film transistor (Flat Panel Detector) using a thin film transistor (TFT).

Among these detectors, there is a trend in recent years to obtain a digital x-ray image by using a flat panel detector in consideration of a reduction in image quality, a reduction in dose of a patient exposure, an inspection efficiency, and an installation easiness. The flat panel detector has a table bucky, Or stand bucky in the form of an electronic cassette.

These cassettes are generally rectangular in shape with one corner being longer than the other, so if necessary, the cassette can be rotated and mounted in a direction perpendicular to the width and height of the cassette.

However, conventionally, there has been a problem that the cassette is detached from the bucky and the orientation is changed and then reinstalled. Further, even when only the cassette is rotated without disassembling the bucky, since the center of rotation of the cassette is fixed, only the axis rotation of the cassette is possible.

Therefore, in order to photograph the upper body or the head of the examinee having a large height, it is inconvenient that the person to be examined must climb over the pedestal because the cassette is simply rotated. In addition, there is a method of allowing the detector itself to ascend and descend, but in this case, a complicated structure must be applied, which increases the number of components and increases manufacturing time and cost.
