Catheter path planning method based on vascular model

Abstract

The invention discloses a catheter path planning method based on a vascular model, comprising: constructing a vascular three-dimensional image model; splitting the three-dimensional image model into aplurality of linear vascular models and bent vascular models; splitting each linear vascular model into a plurality of linear vascular sections, calculating a center point of each linear vascular section, connecting all the center points of each linear vascular model to obtain catheter paths of the linear vascular models; splitting each bent vascular model into a plurality of bent vascular sections, selecting a path point on the inner wall of each bent vascular section, connecting all the path points of each bent vascular model to obtain catheter paths of the bent vascular models; connectingthe catheter paths of the linear vascular models and the bent vascular models according to the three-dimensional image model to obtain a catheter path of the vascular model. The method allows automatic generation of a catheter path and has lower requirements on surgeons' operating skills such that more surgeons can place a catheter.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a catheter path planning method based on a blood vessel model. Background technique [0002] Interventional therapy for endovascular diseases is an emerging technology in recent years, and interventional catheters are one of the key medical devices for implementing this technology. When performing vascular interventional therapy, first puncture the blood vessel with a puncture needle, then insert the intervention tube into the blood vessel, then insert the guide wire into the intervention catheter through the tapered port at the end of the intervention catheter, and guide the intervention catheter along the guide wire to the Advance to the target blood vessel, and finally pull out the guide wire to use the interventional catheter for the next step of inspection and treatment. [0003] In the prior art, when the interventional catheter is pushed forward along the...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the interventional catheter is pushed forward along the guide wire to the target vessel, the route of the interventional catheter is placed manually according to the condition of the blood vessel, which is easily affected by the doctor's experience and subjective factors, and has great influence on the doctor's operation. higher skill

Due to the expansion of the scale of the hospital and the increase of patients, the waiting time for patients to undergo surgery is increased under the condition of a certain number of doctors, resulting in a decline in the quality of medical services.
