Abstract

The invention discloses a fractional flow reserve calculation method and device, electronic equipment and a readable storage medium. According to the method provided by the invention, the pressure drop predicted value is determined through the arterial characteristic parameters after dimension reduction, so that compared with a three-dimensional fluid mechanics calculation method, the calculation speed is higher, pressure drop corrected value prediction processing is performed on the pressure drop predicted value, the obtained pressure drop corrected value is used for correcting the pressure drop predicted value, and the defect that the pressure drop predicted value is inaccurate is overcome. Therefore, the whole process of calculating the fractional flow reserve not only ensures that the calculation speed is superior to that of a traditional method, but also ensures that the final calculated fractional flow reserve is high in accuracy.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a method, device, electronic equipment and readable storage medium for calculating blood flow reserve fraction. Background technique [0002] Fractional Flow Reserve (FFR) is defined as the ratio of the maximum blood flow that a diseased vessel can provide to the maximum blood flow that the vessel can provide when it is completely normal. The ratio of the pressure distal to the lesion stenosis to the proximal arterial pressure was measured in the state of maximum hyperemia. This index is considered to be the "gold standard" for judging the degree of ischemia in diseased vessels. [0003] However, in the measurement methods currently used, the invasive measurement method will cause damage to the human body, and the current non-invasive measurement method cannot guarantee the calculation speed and calculation accuracy at the same time, and the practicability is not stro...
