It is an equipment that allows you to take an x-ray and process the image with a computer so that you can view it as a video in real time on a monitor when you see whether the reduction is well done. It is a necessary equipment especially in orthopedic surgery or neurosurgery.

In the case of C-arm, the amount of exposure is less than that of a fixed X-ray imaging device, but while the C-arm is turned on during surgery (that is, while pressing the switch, it is about 30 seconds to 1 minute depending on the person operating the X-ray imaging device) The surgeon (here, the term'operator' includes all doctors, nurses, surgical assistants, operators of X-ray imaging equipment, etc., hereinafter the same applies), so after a major operation that takes several hours, the operator Due to the long exposure to radiation, the amount of radiation exposure increases, and this causes extreme fatigue after surgery, as well as a lot of damage from radiation such as cancer or leukemia, if you are repeatedly exposed to radiation for a long time. Occurs.

In addition, a stop for determining a radiation area of the generated X-ray rays is positioned in the X-ray generator of the X-ray imaging apparatus.

The aperture controls the amount of opening and closing of the outlet from which the X-ray rays are emitted to determine the radiation area of the X-ray rays.

As a prior patent related to the present invention, Korean Patent No. 0936075'X-ray irradiation range control device' has been proposed.

Korean Patent No. 0936075'X-ray irradiation range adjusting device' is a base plate having an opening through which an X-ray wave is incident through an X-ray tube, and four shutter panels that independently move the opening in different directions to adjust the opening degree of the opening. , Comprising four shafts and a motor for independently driving the four shutter panels, respectively.

However, Korean Patent No. 0936075'X-ray irradiation range control device' allows the radiation to be blocked because the X-ray rays pass through the opening as they are, so the amount of radiation exposure increases because the patient or operator is exposed to the radiation for a long time. As a result, there is a problem that a lot of damage due to radiation such as cancer or leukemia occurs when the operation of being exposed to radiation for a long time is repeated, as well as extreme fatigue after surgery.
