Background
In recent years, minimally invasive techniques have rapidly developed and become widespread, with a considerable part of the work being to perform deep tissue target punctures under CT. Ct (computed tomography), that is, electronic computed tomography, uses precisely collimated X-rays, etc. to scan sections of a human body one after another together with a detector with extremely high sensitivity, has the characteristics of fast scanning time, clear image, etc., and can be used for the examination of various diseases. The CT scanning requires that a human body lies down and enters the CT machine to scan the cross section of the human body layer by layer. Therefore, unlike the puncture under B-ultrasound or DSA (digital subtraction angiography), the puncture under CT cannot be performed under real-time dynamic observation, and needs to be performed step by step in the CT scanning plane, and often needs to be adjusted many times during the puncture process, which is time-consuming, long-lasting, and has a large error.
