Positioning device for CT image

Abstract

The invention relates to the technical field of CT image application, and further discloses a positioning device for the CT image. A base is included, and four supports are fixedly connected to the bottom of the base. A first connecting rod is movably connected to the interior of the base; an adjusting gear is fixedly connected to the outer part of the first connecting rod; the top of the first connecting rod is fixedly connected with an outer adjusting wheel; a second connecting rod is movably connected into the base and located on the left side of the first connecting rod, a first adjustingrod is fixedly connected to the top of the second connecting rod, lock holes are formed in the left side wall and the right side wall of the first adjusting rod, and a second adjusting rod is connected into the first adjusting rod in a sleeved mode. The positioning device for the CT image has the advantages of being convenient to position and adjust, not influencing observation and the like, and therefore the problems that when the CT image is clamped and fixed to a lamp box for observation, adjustment is complex in the clamping process, the observation angle is difficult to adjust, shieldingis likely to be caused, and observation is influenced are effectively solved.

Description

technical field [0001] The invention relates to the technical field of CT image applications, in particular to a positioning device for CT images. Background technique [0002] CT is computerized tomography. It uses precisely collimated X-ray beams, γ-rays and ultrasound, etc., together with highly sensitive detectors, to perform cross-sectional scans one after another around a certain part of the human body. It has a fast scanning time, It can be used for the examination of various diseases due to its clear image. According to the different rays used, it can be divided into X-ray CT (X-CT) and γ-ray CT (γ-CT). [0003] The device that uses CT technology for imaging is called CT imager, which has been widely used nowadays, and the CT image pictures scanned by CT imager are basically placed on the light box after being washed out and diagnosed by radiologists. When it is fixed, it is mostly in a clamping state, so when the light shines on the image, it is easy to cause occlu...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a positioning device for CT images, which has the advantages of convenient positioning and adjustment without affecting observation, and solves the problem that the clamping and fixing of CT images on the light box for observation will make the adjustment complicated and difficult during clamping. Adjust the viewing angle and easily lead to occlusion and cause problems that affect observation
