Optimal lung puncture operation path planning method and lung puncture operation navigation system

Abstract

The invention discloses an optimal lung puncture operation path planning method, and relates to the technical field of computers. The method includes the steps: S1 quantitatively analyzing constrained conditions of clinical lung puncture surgery standards based on preoperative CT (computed tomography) images of patients, and filtering out puncture operation paths without meeting the constrained conditions; S2 quantitatively analyzing objective conditions of the clinical lung puncture surgery standards based on the preoperative CT images of the patients, and building sub-objective functions based on path risks; S3 building an optimal path model based on the constrained conditions and the objective conditions, and calculating solution sets of optimal paths. The invention further discloses a lung puncture operation navigation system for planning preoperative operation paths by the optimal lung puncture operation path planning method. According to the method, operation path solution sets of lung puncture operations are calculated without artificially setting weight parameters between sub-objectives, subjective factor interference is avoided, and optimal operation path guidance is provided for lung puncture operation navigation.

Description

technical field [0001] The invention belongs to the technical field of computers, and relates to an optimal path planning method for lung puncture surgery, and a lung puncture surgery navigation system for planning preoperative surgical paths by using the optimal path planning method for lung puncture surgery. Background technique [0002] CT (Computed Tomography) uses a precisely collimated X-ray beam and a highly sensitive detector to scan a certain part of the human body one by one, and expresses the degree of absorption of X-rays by organs and tissues in different gray levels. , for example, on a chest CT image, the low-density area represents the trachea and lung parenchyma, and the high-density area represents blood vessels, chest cavity, bones, etc., which has the characteristics of fast scanning time and clear images, and can be used for the examination of various diseases. The doctor's observation and diagnosis of the disease provide a convenient and reliable basis....

Problems solved by technology

The weighing methods of multiple goals are all subjectively set by doctors. Therefore, with different weighing methods, the results of path calculation may be completely different, which is greatly affected by subjective factors.

In addition, most of these planning methods are path planning methods for abdominal or head puncture surgery, and lung puncture surgery has its own unique clinical standards, and there is no published optimal path planning method for lung puncture surgery
