Focus precise positioning CT monitor

Abstract

The invention discloses afocus precise positioning CT monitor which comprises a scanning frame, a movable supporting base and a bed body. The movable supporting base is installed on one side of the scanning frame. Shielding assemblies are symmetrically installed on the two sides of the scanning frame. The bed body is fixedly installed on the top of the movable supporting base. A plurality of lightshielding pieces are arranged on the top of the bed body. By using the shielding assemblies on the scanning frame and the light shielding pieces on the bed body in cooperation, the closed-type scanning is conducted on the focus on the body of a person lying on the bed body, it is avoided that the illumination of X-rays is affected by external light rays, and therefore the scanning intensity of X-rays is increased, and the detection accuracy of the CT monitor is improved.

Description

technical field [0001] The invention relates to the technical field of medical CT detection equipment, in particular to a CT monitor for precise positioning of lesions. 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. With the characteristics of fast scanning time and clear images, it 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) and γ-ray CT (γ-CT). [0003] At present, CT diagnosis is one of the main diagnostic methods for checking diseases in hospitals. The CT diagnosis method often uses X-rays to take pictures of the patient's diseased parts and take accurate images to determine the patient's condition. During the detection process, most All...

Problems solved by technology

[0004] According to the inquiry data, it is known that the external light can easily affect the X-ray rays, reducing the effect of X-rays, thereby affecting the detection accuracy of the CT detector, and even causing the shooting effect to be very unsatisfactory, requiring the patient to take a new shot (CT detection Nuclear radiation has an impact on the human body), and in severe cases, it will cause medical staff to watch unclear images, leading to diagnostic errors and affecting the best timing of treatment for patients. For this reason, we propose a CT monitor for precise lesion positioning
