摘要：
The claimed technical solution refers to the section of medical X-ray equipment. It is intended for. limiting the radiation beam emitted from the X-ray emitter, and forming a narrow fan-beam X-ray diagnostic apparatus of the scanning type. The purpose of this operation is to reduce the radiation load on the object of research by providing an optimal balance between slotted channels inlet and outlet aperture (s 1 / s 2 = 1.0). The technical result of the claimed utility model is expressed in increasing the accuracy of setting the X-ray collimator slit. It is achieved in that the X-ray collimator slit, comprising entrance and exit slit diaphragm of a material with high atomic number, with a relative width of gap channels s 1 / s 2 ~ 2.5, where s 1 - entrance aperture width of the slit, as 2- width of the gap output aperture, the collimator generates a narrow fan-shaped X-ray beam from the x-ray radiator located in front of the inlet orifice, the recorded linear detector located behind the exit aperture, the entrance slit diaphragm has a body in the form of a rectangular paral lepipeda with a through hole in the shape of a cylinder of revolution whose axis extends perpendicularly to the central X-ray beam, the housing is provided with two windows, the part of emitter and detector, and the through hole introduced by sliding fit cylinder with two slotted channels extending mutually perpendicularly through the axis of the cylinder, wherein the relative width of the cylinder gap channels is 1 s / s 1 ~ 2.5, where s 1 - the width of the narrower cylinder bore (s = s 12) entrance aperture equipped with a mechanism turning cylinder by 90 ° and a mechanism for fine adjustment of the angular position of the cylinder in the aperture body, moreover, a collimator coupled to the X-ray emitter means adjusting mechanism ensuring smooth movement of the collimator with respect to the x-ray emitter in the direction perpendicular to the plane of the slot channel within ± 4 -5 mm relative
