Abstract

The invention discloses a hemodynamic force simulation method and device. The method comprises the following steps: acquiring a blood vessel image of an artery blood vessel in a predetermined area of a target object; performing level set segmentation on an initial blood vessel model corresponding to the blood vessel image to obtain a segmented blood vessel model; acquiring a boundary condition for simulating a target blood vessel corresponding to the blood vessel model; performing central arterial pressure calculation on the target blood vessel to obtain an inlet pressure value of the target blood vessel; and performing hemodynamic simulation on the target blood vessel by using the boundary condition and the inlet pressure value. The technical problem that in the related technology, potential safety hazards exist in invasive fractional flow reserve measurement, and consequently the reliability of hemodynamic simulation is low is solved.

Description

technical field [0001] The present invention relates to the technical field of hemodynamic simulation, in particular to a hemodynamic simulation method and device. Background technique [0002] Intracranial Atherosclerotic (ICAS) disease is the main cause of stroke. The SAMMPRIS trial showed that, even with optimal medical care, the annual stroke recurrence rate in patients with severe intracranial stenosis was as high as 12%. The VISSIT trial did not show the benefit of intracranial stenting. However, one reason for this is the relative inexperience with the use of devices and stenting procedures, leading to complications; another important factor is the failure to select patients with the highest risk of recurrent stroke. Optimal medical conditions alone are not enough, and many patients may benefit from vascular intervention. ICAS traditionally treats patients based on the degree of luminal stenosis. Hemodynamics, along with plaque characteristics, are important facto...
