Description

Visual display and synchronization device of x-ray system

The present invention relates to a visual display device and a synchronization device of a computed radiography (CR) x-ray system.

Recently, thanks to the development of science and medical technology, the field of radiation as a diagnostic equipment has grown rapidly, and for most patients, radiological examination equipment has become a universal diagnostic method. Diagnostic equipment generally popularized as radiation-related equipment is an X-ray system. X-ray systems are used to visualize anatomical structures and to detect the presence of pathologies, diseases or abnormal anatomical structures.

The X-ray system may be classified into a film, a CR, and a digital radiography method according to an image acquisition method.

The film method is the most common photographing method for X-ray imaging. X-rays passing through a subject form a latent image on the photosensitive film, and the photosensitive film is developed by chemical treatment in a dark room to visualize the image.

In the CR method, an image plate (IP) cassette made of accumulator phosphors (or photomagnetic phosphors) instead of the photosensitive film is used in the film method. When it is stored in the form of energy and stored as a latent image, and when the IP cassette is inserted into the image reader and subjected to laser light, it emits light according to the amount of X-rays incident on the IP cassette, and the reader emits light. Is converted into an electrical signal and then converted into a digital image.

The DR method includes a camera method and a panel method using a charge-coupled device (CCD). Among them, the CCD method uses a narrow and long CCD sensor, which is divided into tiny rooms called pixels inside the CCD sensor. The intensity of the charge is determined by the amount of X-rays entering the pixel and the resulting electrical signal is digitized after passing through an analog-to-digital converter via a cable. Unlike the CR method, the DR method does not require a reader and can immediately obtain a digital image.

The X-ray system of the DR method is mainly used in a large hospital because it is more expensive than the x-ray system of the film method and the CR method, and a relatively low cost DR or film X-ray system is used in a small hospital.

On the other hand, the CR-type X-ray system must prepare a plurality of IP cassettes according to the number of shots and shoot them, and convert them into digital images through a reader (that is, a developer) provided in a space separated from the shooting place after shooting is completed. There is discomfort. In addition, the CR-type X-ray system digitizes only the X-ray reader, and since it is not linked to the controller that controls the exposure amount and the shooting time of the X-ray, it is difficult to obtain information such as the exposure amount and the shooting time of the X-ray. .

In particular, in recent years, radiation doses, such as x-ray systems, have been important for patients. Therefore, there is a growing demand for a device capable of synchronizing exposure dose and photographing time information in a conventional CR method X-ray system.

Accordingly, the present invention was derived to solve the above-described problem, and to provide a visual display apparatus and a synchronization apparatus of an X-ray system capable of synchronizing exposure information and visual information to an image of a subject acquired in a CR-based X-ray system. do.
