Abstract

The invention discloses an ANN-based fractional flow reserve prediction method and device, equipment and a medium. The method comprises steps that all the basic data in a reference database are divided into modeling data and model detection data according to a specified proportion; the modeling data is trained through a specified algorithm to obtain a fractional flow reserve prediction model; thefractional flow reserve prediction model is checked by the model detection data; whether the check result is consistent with the specified requirement is determined, if yes, the fractional flow reserve prediction model is used to predict the fractional flow reserve of a subject. The ,method is advantaged in that the fractional flow reserve can be accurately predicted, accuracy can reach 98%, average accuracy can reach more than 90%, the application range is wide, prediction can be performed without knowing the formula relationship between input parameters and reference data, and greater freedom is realized.

Description

technical field [0001] The present invention relates to the field of medical detection, in particular to an ANN-based blood flow reserve fraction prediction method, device, equipment and medium. Background technique [0002] Both coronary angiography and intravascular ultrasound are considered the "gold standard" for diagnosing coronary heart disease, but they can only perform imaging evaluation on the degree of lesion stenosis, but it is unknown how much the stenosis affects the distal blood flow; Fractional flow reserve (FFR) has now become a recognized index for functional evaluation of coronary artery stenosis, and its most important function is to accurately evaluate the functional consequences of an unknown coronary artery stenosis. [0003] Fractional flow reserve (FFR) refers to the ratio of the maximum blood flow that can be obtained by the myocardial region supplied by the target measurement vessel to the theoretical maximum blood flow that can be obtained by the s...
