Pulmonary artery evaluation method and device, computer equipment and storage medium

Abstract

The invention relates to a pulmonary artery evaluation method and device, computer equipment and a storage medium. According to the method, medical image data and pulmonary artery feature information of a patient are obtained, a geometric model of a pulmonary artery structure is constructed according to the medical image data, then, fluid mechanics calculation is performed on the geometric model of the pulmonary artery structure according to preset boundary conditions, and at least one piece of blood flow feature information of the pulmonary artery structure is obtained. According to the evaluation method, non-invasive evaluation of pulmonary arterial hypertension is achieved. Compared with traditional invasive evaluation, the invention has the advantage that the damage to the body of a patient is reduced. Moreover, the evaluation method can finally provide the blood flow feature information of any site on the pulmonary artery. Compared with a traditional invasive evaluation method capable of only providing single blood flow feature information corresponding to several fixed sites, the pulmonary artery evaluation method provided by the invention can be used for more comprehensively evaluating the pulmonary arterial hypertension, and the accurate evaluating result can be obtained.

Description

technical field [0001] The present application relates to the technical field of medical detection, in particular to a pulmonary artery evaluation method, device, computer equipment and storage medium. Background technique [0002] Pulmonary hypertension is a hemodynamic and pathophysiological state in which pulmonary artery pressure rises above a certain threshold, leading to right heart failure. Pulmonary hypertension is a common and frequently-occurring disease with high morbidity and mortality. Three factors affect pulmonary artery pressure: pulmonary vascular impedance, cardiac output, and pulmonary capillary wedge pressure. Any condition that affects the above factors can lead to pulmonary hypertension. [0003] At present, the diagnosis and evaluation of pulmonary hypertension commonly used in clinical practice are mainly realized through right atrial catheterization. Right atrial catheterization is an invasive examination. Catheter to the right heart chamber and g...
