Puncture parameter generation method based on three-dimensional image

Abstract

The invention discloses a puncture parameter generation method based on a three-dimensional image. The method comprises the steps of acquiring a medical image, and reconstructing 3D model data; acquiring central point coordinate position information of a target object model in 3D space; selecting a simulated puncture point from the skin surface in the 3D model data, obtaining three-dimensional space coordinates of the puncture point, and generating a connecting line between the selected puncture point and an objective target point; utilizing the puncture point and the objective target point ofthe connecting line not penetrating through an organ model for calculating a three-dimensional space intersection point of the connecting line and the surface of a target object, wherein the distancefrom the puncture point to the three-dimensional space intersection point is puncture depth; conducting skin transparent rendering and the bone rendering; determining an actual position of the puncture point according to the curve distance between the objective target point and the skin surface, and outputting the puncture depth and three-dimensional coordinate parameters. By means of the method,accurate quantitative data is obtained for individualized cases before the puncture operation, actual operating parameters are provided for minimally invasive treatment, and the clinical individualized and precise demands are met.

Description

technical field [0001] The invention relates to a medical image processing method in a medical auxiliary system, in particular to a method for generating puncture parameters based on a three-dimensional image. Background technique [0002] With the development of modern surgical technology towards precision and minimal invasiveness, the visualization of 3D medical images for individualized anatomy has been widely used. At present, many applications are aimed at understanding the spatial relationship of anatomy and the detection of lesions and surrounding tissues. Understanding and observing the relationship between shape and adjacency, this technology is useful for revealing the individualized internal organ anatomy, whether the blood vessel is a variable structure, and their relationship with the lesion, planning the surgical approach, resection site, and formulating emergency response before surgery. Apps such as Protocols provide key reference information about the anatom...

Problems solved by technology

The main reason is that there is no individualized biometric information to support the design of the preoperative plan. Doctors mainly rely on experience to determine the puncture point, and need to use imaging equipment to repeatedly verify the puncture process during the operation, but there are variations in the vascular structure. or other individual differences can lead to unexpected situations

[0004] See the Chinese invention patent application number CN201210417086 titled "Percutaneous Puncture Operation Planning Method and System", which provides a virtual puncture method, but does not calculate the puncture parameters for individualized 3D models Application and decision-making cannot provide quantitative parameters, and cannot fully meet the needs of clinical individualization and precision
