Abstract

The invention belongs to the field, particularly relates to a catheter detection method for a vascular aneurysm interventional operation navigation system, and aims to solve the problem that an interventional catheter in an X-ray transmission image in an intravascular aneurysm repair operation cannot be accurately segmented and tracked in real time. The method comprises the following steps: acquiring an X-ray transmission video sequence of a region containing a catheter as a to-be-detected sequence, generating a segmentation mask sequence through a trained encoding and decoding structure according to the to-be-detected sequence, and covering the to-be-detected video with a binary segmentation mask sequence to obtain a video sequence of the catheter. The accuracy and speed of segmentation and tracking of the X-ray transmission image interventional catheter in the intravascular aneurysm repair operation are improved, and the real-time performance required by an operation tracking algorithm is met.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a catheter detection method and system for a vascular aneurysm interventional surgery navigation system. Background technique [0002] Minimally invasive interventional surgery navigation system is an emerging cardiovascular disease treatment system, which integrates computer science, artificial intelligence, automatic control, image processing, multimodal fusion, target segmentation, three-dimensional imaging, virtual reality training and clinical treatment, etc. A new approach that integrates multiple technologies. This method uses medical images of multiple modalities to assist doctors to puncture interventional surgical instruments from the radial artery or femoral artery to the stenotic part of the blood vessel for treatment. This method can improve the quality of surgery, reduce surgical trauma, and reduce patient pain. [0003] Although this method ha...
