Problems solved by technology

Existing collimator devices that use ray sources to safely detect objects all use adjustment mechanisms to control two movable semi-collimator devices to form collimation seams. It is installed in a shielding box, so people cannot control the size of the collimation slit by direct observation or measurement, but can only be controlled by the formed image or other indirect ways. Not only the adjustment method is complicated, but it is also difficult to achieve the ideal alignment. Straight seam width requirements

Embodiment Construction

[0016] Referring to FIG. 1 and FIG. 2 , the present invention includes a left half collimator, a right half collimator and a shielding box 13 . The left half-collimator is composed of the left bracket 1 and the left vertical lead plate 2 and the left horizontal lead plate 4 connected with its inner wall, and the right half-collimator is composed of the right bracket 8 and the right vertical lead plate 7 connected with its inner wall And right horizontal lead plate 6 forms. Left vertical lead plate 2, left horizontal lead plate 4, right vertical lead plate 7 and right horizontal lead plate 6 can adopt different thickness sizes. The left bracket 1 and the right bracket 8 can be a symmetrically arranged split structure or an integral structure, and its shape is L-shaped, or any of a groove type and a plane type. The upper and lower ends of the left half collimator and the right half collimator are connected into one body through the positioning spacer 3, the adjustment screw 10 ...

Abstract

An integral typed shielding collimator relates to a radiation imaging detection technical field. The invention includes a left half collimator, a right half collimator and a shielding box. The invention is characterized in that: the left half collimator consists of a left bracket and a left vertical lead plate as well as a left horizontal lead plate which are connected with an inner wall of the left bracket. The left half collimator and the right half collimator are connected at upper ends and lower ends through a location space sleeve, an adjusting screw and a locking nut are connected into a whole body, a collimating slit is formed between the left half collimator and the right half collimator. The collimating slit is provided with a transparent fit strip. A whole body movement can be realized by fixing the shielding box on a periphery of the left half collimator and the right half collimator through the adjusting screw and the adjusting nut. Compared with the prior art, the invention meets a requirement of the imaging and focusing which facilitates the adjustment and control of a diographic source.

Description

technical field [0001] The invention relates to the technical field of radiation imaging detection, in particular to a collimator device for safely detecting objects with a radiation source. Background technique [0002] In order to improve the quality of radiation imaging, a collimator device is usually used to focus the ray source. The quality of the focus depends on the control of the collimation slit in the collimator device and the shielding effect on redundant rays. Existing collimator devices that use ray sources to safely detect objects all use adjustment mechanisms to control two movable semi-collimator devices to form collimation seams. It is installed in a shielding box, so people cannot control the size of the collimation slit by direct observation or measurement, but can only be controlled by the formed image or other indirect ways. Not only the adjustment method is complicated, but it is also difficult to achieve the ideal alignment. Straight seam width requir...
