Abstract
A method for predicting fractional flow reserve on the basis of machine learning is disclosed. The disclosed method for predicting fractional flow reserve comprises the steps of: receiving a class of a target cardiac blood vessel and a feature value for the target cardiac blood vessel extracted from an optical coherence tomography (OCT) image of a lumen of the target cardiac blood vessel; and predicting an FFR value for the target cardiac blood vessel using at least one pretrained predictive model, the class of the target cardiac blood vessel, and the feature value, wherein the feature value includes at least one of a proximal lumen area (PLA) value, a minimal lumen area (MLA) value, a percent area stenosis value, a distal lumen area (DLA) value, a lesion length value, a rupture presence/absence value, a plaque area value, and a lipid rich value.
