Abstract

The application discloses a blood flow reserve fraction calculation method, device, electronic equipment and readable storage medium. The method provided by this application determines the pressure drop prediction value through the arterial characteristic parameters after dimension reduction, so compared with the calculation method of three-dimensional fluid dynamics, the calculation speed is faster, and the pressure drop correction value prediction processing is performed on the pressure drop prediction value to obtain The correction value of the pressure drop corrects the predicted value of the pressure drop, which overcomes the inaccurate shortcomings of the predicted value of the pressure drop. Therefore, the whole process of calculating the blood flow reserve fraction not only ensures that the calculation speed is better than the traditional method, but also ensures the blood flow obtained in the final calculation. Reserve scores are highly accurate.

Description

Fractional blood flow reserve calculation method, device, electronic device and readable storage medium technical field The application relates to medical technology field, be specifically related to a kind of blood flow reserve fraction calculation method, device, electronic equipment and readable storage media. Background technique Fractional Flow Reserve (FFR) is defined as the maximum blood flow that a diseased vessel can provide. The ratio of the flow to the maximum blood flow that the vessel can provide when it is completely normal, which is commonly measured by intervening a guide wire with pressure or The microcatheter measures the ratio of the pressure distal to the lesion stenosis to the proximal arterial pressure in the maximally hyperemic state. This indicator is considered to be a The "gold standard" for diagnosing the degree of ischemia in diseased vessels. However, in the measurement method currently adopted, the invasive measurement method can caus...
