Technical Field

The invention relates to the technical field of CT examination, in particular to a shallow breathing control mechanism for chest CT detection and puncture.

Background

In the CT, an X-ray beam is used to scan a certain thickness of a layer of a human body, and a detector receives the X-ray transmitted through the layer, converts the X-ray into visible light, converts the visible light into an electrical signal by photoelectric conversion, and inputs the electrical signal into a computer to process the electrical signal to form an image.

The percutaneous lung aspiration biopsy under the guidance of CT is widely applied, and the aspiration biopsy has the advantages of no need of operation, small wound, simple and convenient operation, low operation risk and the like, so that the patient is more easily accepted. However, how to improve the puncture accuracy and reduce the complications is two major issues of clinical research at present. The accuracy rate and complication occurrence of puncture are mainly determined by the position, shape and size, adjacent relation, and experience and proficiency of an operator of a diseased part, the first three items are objective factors and cannot be changed, and the experience and proficiency of the operator are the key for influencing whether puncture is smooth or not, and because the lung can continuously move along with the thorax and the diaphragm during breathing, the positioning of a puncture object in the CT scanning process can be influenced, and the final puncture precision is influenced. The problem of fixing the human body and the breath in the scanning and puncturing process needs to be solved, so that the puncturing precision is improved. The existing devices focus on controlling human body movement, and have complex structures, inconvenient operation and no respiration inhibition related structures.
