Description

Shooting position and area display device of collimator for X-ray equipment

The present invention relates to a collimator for x-ray equipment. More specifically, by using the X-ray equipment to display the imaging position for the X-ray (radiation) irradiation on the affected area to diagnose the disease, and to display the imaging area to specify the X-ray irradiation range at the displayed position It relates to a photographing position and area display device of the collimator for the X-ray equipment.

For the purpose of early and final diagnosis of disease, the utilization of diagnostic X-rays is steadily increasing. On the other hand, as a requirement of excellent X-ray equipment, it has excellent electrical characteristics and is convenient to use, and the output performance is maintained at the initially set level so that there is no pain and inconvenience of the patient, as well as the minimum radiation exposure dose (exposure dose). It is necessary to provide maximum medical information by representing the information in the human body in an image of excellent quality.

The performance of such diagnostic X-ray equipment is determined by the X-ray output, that is, the tube voltage, tube current, and irradiation time of the X-ray tube. In use, the characteristics must be reproducible.

In particular, when radiation is used for the purpose of diagnosing a disease, it should only be used if the allowable range of radiation exposure is greater than the loss to be gained from the use and the probability of radiation exposure by reducing the possible exposure. · It should be possible to reduce the occurrence of non-probability effects. Therefore, the role of the collimator to control X-ray flux in radiography is very important.

The collimator is installed in the center of the X-ray irradiation side of the X-ray equipment, X-ray radiation field irradiated from the X-ray equipment when X-ray imaging a specific part of the human body, that is, the affected area Control and display the X-ray imaging position on the human body while limiting the spread of X-rays. The conventional collimator, as shown in Figure 1, is equipped with a light source (internal light source) inside the inclined at 45 ° by installing a reflector (having the property of transmitting X-rays) to illuminate the size of the irradiation range We can see the shape of and with our eyes, and the transparent cross (not shown) with black crosshairs is placed so that the center point of the irradiation range can be observed, and a plurality of lead shields are needed to freely control the size and shape of the X-ray flux.

In this way, it is possible to observe the expected irradiation range irradiated to the affected area, to adjust the exact X-ray irradiation range for the patient, and to define the shape and size of the X-ray flux according to the inspection site to prevent radiation exposure to unnecessary areas. By preventing it, the dose of the patient can be reduced.

However, most diagnostic X-ray equipments used in medical institutions have different results such as the output of the device and the accuracy of the shooting conditions, even if they are the same type of equipment. This is very important, provided that the lamp and the reflector for the light emitted from the lamp are irradiated to the affected part, and the transparent glass with black crosshairs to display the cross point indicating the shooting position on the affected part must be provided. The X-ray imaging position can be checked visually.

When the 1-1,1-2 laser module and the 2-1,2-2 laser module are irradiated on the same irradiation surface, they are displayed on the affected area with a crosspoint indicating a shooting position for X-ray irradiation. When the 1-1,1-2 laser module and the 2-1,2-2 laser module are irradiated in parallel with each other at random intervals on the same irradiation surface, X-rays centering on the crosspoint A photographing position and area display apparatus of a collimator for x-ray equipment, characterized in that displayed on the affected area in a grid position indicating the photographing area for designating the irradiation range.
Display the first X-axis light bar, the second X-axis light bar and the first X-axis light bar spaced apart in the Y-axis direction, and the first X-axis light bar and the second X-axis light bar in the Y-axis direction. The first Y-axis light bar and the first and second X-axis light bars that cross the first and second X-axis light bars and are spaced apart in the X-axis direction from the first Y-axis light bar. A light source body displaying a boundary of an irradiation range to which X-rays are irradiated; And

A driving to adjust the light source body to move and adjust at least one of the first and second X-axis light bars in the Y-axis direction and to move and adjust at least one of the first and second Y-axis light bars in the X-axis direction Collimator for X-ray equipment comprising a sieve.
The method of claim 5,

The driving body moves and adjusts both the first and second X-axis light bars in the Y-axis direction such that the first X-axis light bar and the second X-axis light bar overlap each other or are spaced apart from each other in the Y-axis direction, A collimator for X-ray equipment, characterized in that the first and second Y-axis light bar overlaps each other or is spaced apart from each other in the X-axis direction to move and adjust both the first and second Y-axis light bar in the X-axis direction. .
The method of claim 5,
