Stable-type CT machine with adjusting function

Abstract

The invention relates to a stable-type CT machine with an adjusting function. The stable-type CT machine with the adjusting function comprises a main engine, a base, a transmission frame and a bed, and further comprises an adjusting mechanism and a fixing mechanism, wherein the adjusting mechanism comprises a driving assembly, a connection board and a bed board, the driving assembly comprises a telescoping frame, a movable board, two hinged boards and two driving units, the fixing mechanism comprises a fixing box, a fixing assembly is arranged in the fixing box, and the fixing assembly comprises a rotary knob, a rotating shaft, a gear, two racks and two fixing boards. According to the stable-type CT machine with the adjusting function, through the adjusting mechanism, the length of the bedcan be adjusted, thus the use requirements of patients in different heights are met, through the fixing mechanism, the heads of the patients can be fixed, and effects of change of head positions of the patients on examination results are avoided.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a stable CT machine with an adjustment function. Background technique [0002] CT (Computed Tomography), that is, electronic computer tomography, it uses precisely collimated X-ray beams, γ-rays, ultrasound, etc., together with highly sensitive detectors, to conduct cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used for the examination of various diseases; according to the different rays used, it can be divided into: X-ray CT (X-CT), ultrasonic CT (UCT) and γ-ray CT (γ-CT) )Wait. [0003] The length of the existing CT machines is mostly fixed, which causes the legs of the patients who are too tall to lie flat on the bed, which brings discomfort to the patients and affects the detection effect. Not only that, the existing CT When the machine is performing detection, the...

Problems solved by technology

[0003] The length of the existing CT machines is mostly fixed, which causes the legs of the patients who are too tall to lie flat on the bed, which brings discomfort to the patients and affects the detection effect. Not only that, the existing CT When the machine is performing detection, the patient's head needs to be kept in a fixed position for a long time. If the patient's head position changes, it will affect the detection results and reduce the practicability of the device.
