Problems solved by technology

[0004] The above calculation process is not only cumbersome and complicated, but also very costly, especially the time cost. To obtain the hemodynamic index of a single atrial appendage case, it takes more than ten hours of calculation time for the CFD flow field simulation calculation alone, which is difficult to meet the clinical requirements. The need for real-time diagnostics

Abstract

The embodiment of the present application discloses a hemodynamic index determination method, device, device, and storage medium, wherein the method includes: responding to a hemodynamic index prediction request, determining the hemodynamic index prediction request The point cloud coordinate data set corresponding to the medical image in the medical image; the first space coordinate transformation is performed on each point cloud coordinate data in the point cloud coordinate data set to obtain the first point cloud coordinate data after space coordinate transformation; The point cloud coordinate data is subjected to first high-dimensional space mapping processing to obtain second point cloud coordinate data with a first preset dimension; wherein, the first preset dimension is greater than the initial dimension of the first point cloud coordinate data ; Splicing the second point cloud coordinate data and the first point cloud coordinate data to form a splicing vector; performing dimension reduction processing on the splicing vector to obtain a hemodynamic index.

Description

technical field [0001] The embodiments of the present application relate to the technical field of biomedical engineering, and relate to, but are not limited to, a method, device, device, and storage medium for determining a hemodynamic index. Background technique [0002] At present, it is very convenient to obtain medical image data at the heart position through computerized tomography (Computed Tomography, CT) technology or magnetic resonance imaging (Magnetic Resonance Imaging, MRI) technology, and can obtain the atrial appendage through three-dimensional reconstruction technology. Three-dimensional geometric model, but the hemodynamic index cannot be obtained directly. [0003] In related technologies, when obtaining hemodynamic indicators, the geometry of the atrial appendage is firstly extracted from medical images, and then meshed to perform flow field simulation (Computational Fluid Dynamic, CFD) calculations, and finally from the simulated flow field The correspon...
