Movable lamp-type collimator

Abstract

The present invention relates to a movable lamp-type collimator configured to simultaneously move a lamp unit, which emits light, and a condensing lens, which condenses the light, such that the lamp unit and the condensing lens clearly display a cross point at a specific part of a human body, and the lamp unit and the condensing lens return to original positions after displaying the cross point, thereby enabling accurate irradiation of X-rays from X-ray equipment to a specific part of the human body (inflicted part), which is the X-ray imaging position, without interfering with the X-rays. To this end, a collimator according to the present invention comprises: a body case having an inlet and an outlet, through which X-rays enter and exit, and a transmission window provided with a cross point; a lamp unit installed inside the body case to emit light for displaying a cross point in the X-ray imaging position; a condensing lens coupled to the front side of the lamp unit to condense light; a PCB substrate coupled to the rear of the lamp unit; a heat radiation plate, to which the PCB substrate is coupled to radiate heat to the outside; a driving means for causing the heat radiation plate, to which the lamp unit is coupled, to make reciprocating movements in left and right directions inside the body case; and a shielding unit movably installed inside the body case and provided with a plurality of shielding plates to adjust the irradiation direction and radiation range of X-rays and light.

Description

technical field [0001] The present invention relates to a collimator arranged in X-ray (X-Ray) equipment and used to adjust the irradiation range of the irradiated X-rays and to limit the diffusion of X-rays. More specifically, it relates to a collimator that can be used to moving the lamp unit for emitting light and the condensing lens for converging the light to the exact center of the radiation optical axis, and re-moving the lamp unit and the condensing lens to the center of the radiation optical axis after shooting Laterally, it is different from the existing method of using a mirror to irradiate light. It will neither have a slight impact on the image, nor need to worry about the inconsistency between the X-ray irradiation field and the light irradiation field, so it can be taken as an X-ray A lamp moving collimator that accurately irradiates X-rays to a specific part (affected part) of the human body. Background technique [0002] Usually, the collimator (collimator)...

Problems solved by technology

[0006] However, such a conventional collimator has a structure in which a reflection mirror is attached to the inside of the collimator to reflect the light from the lamp in order to display the intersection point at the X-ray imaging position of the human body. According to this method, when taking X-rays, since the final image is irradiated with radiation through the reflection window of the mirror, it is always Along with the problem of being slightly affected, and the angle of the mirror plays a very sensitive factor in the process of determining the light irradiation field, there are not only many technical difficulties in unifying the light irradiation field and the X-ray irradiation field, but also When used for a long time, there is a problem that it is easy to cause inconsistent irradiation fields
