Background
The image-guided minimally invasive interventional diagnosis and treatment refers to minimally invasive diagnosis and treatment by percutaneous puncture of interventional instruments (puncture needles, catheters, other interventional instruments and the like) under guidance and monitoring of an imaging technology (ultrasound, X-ray, CT, MRI and the like).
In the traditional CT guided minimally invasive technique, firstly, a body surface is marked, and a doctor subjectively controls the needle inserting angle and depth in the minimally invasive treatment process according to personal experience and preoperative CT scanning image data. During the operation process, CT scanning is continuously carried out to determine whether the needle inserting angle is satisfactory or not, if the needle inserting angle is not satisfactory, the angle needs to be adjusted, then CT scanning is carried out again, and if the angle is not satisfactory, the puncture needle needs to be pulled out or the puncture point needs to be replaced, and the needle is inserted again until the satisfactory angle is reached. However, the above operation has the following disadvantages:
1. in the current minimally invasive diagnosis and treatment operation guided by CT, most medical workers operate by hands with years of clinical experience, so that the operators are required to have better perception on the needle insertion angle, and the needle insertion angle can be obtained only by abundant clinical practice operation experience, thereby greatly limiting the clinical application and development of the minimally invasive technology. The development of similar diagnosis and treatment in hospitals with relatively backward technical strength is more difficult;
2. many dangerous blood vessels often exist around the target position (tumor entity) of partial minimally invasive operation, or the tumor entity grows around important viscera or blood vessels, so that more accurate operation is required to avoid such dangerous tissues, the minimally invasive operation is smoothly completed, and the operation difficulty and the operation risk are very high;
3. the needle insertion angle needs to be adjusted in the operation process of the CT guided minimally invasive surgery, so that CT scanning needs to be carried out, one CT scanning needs to be added every time the needle insertion is adjusted, the operation time is increased, the body position of a part of patients cannot be kept for a long time due to the fact that the body position of the patient is not kept for a long time, diagnosis and treatment can be given up, in addition, the radiation dose of the patient is increased through multiple CT scanning, and the burden is increased for the body health of the patient;
