Embodiment Construction

[0043] The method and system for processing hemodynamic index data provided by the embodiments of the present invention relate to a method for non-invasive evaluation of hemodynamic indexes in vessels of interest (such as cerebral aneurysms) using medical image data and CFD simulation and system. Embodiments of the present invention are described to provide a visual understanding of the distribution of hemodynamic indicators for simulating cerebral aneurysms. The numeric representation of an object is typically described here in terms of identity and operand objects. Such operations are virtual operations implemented in computer system memory or other circuitry / hardware. Accordingly, it is to be understood that embodiments of the present invention may be implemented within a computer system using data stored in the computer system.

Abstract

The invention relates to a haemodynamic index data processing method and system. The method comprises collecting medical image data and clinical measurement data; performing image segmentation processing according to the medical image data and the clinical measurement data, and generating specific anatomical model data of the interested blood vessel by using a center line extraction algorithm; carrying out grid division processing on the specific anatomical model data, and carrying out fluid mechanics simulation processing by utilizing boundary conditions, so as to obtain distribution condition data of hemodynamic indexes, the distribution condition data comprising wall surface shear stress, time average wall surface shear stress, an oscillation shear index and a speed streamline; and carrying out visualization processing on the distribution condition data of the hemodynamic indexes so as to display the distribution condition data on a three-dimensional model of the cerebral aneurysm. According to the method and the system, the distribution condition of the haemodynamic indexes in the interested blood vessel can be simulated, visualized and displayed, the processing speed is high, and the visualization precision is high.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for processing hemodynamic index data. Background technique [0002] Due to the continuous development of medical imaging technology, geometric data of vessels of interest such as human brain aneurysms can be obtained. Simultaneously comparing the geometric data difference between the ruptured cerebral aneurysm data and the unruptured cerebral aneurysm data can carry out further risk analysis, but the cause of the risk cannot be analyzed and processed yet. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a method and system for processing hemodynamic index data, by using fluid dynamics (CFD) to simulate the hemodynamics of the vessels of interest based on medical image data and clinical measurement data The hemodynamic index data can be processed according to the distribution status of the med...
