Typical examples of non-culprit lesions identified through deep learning algorithms for the simultaneous detection of both morphological and physiological characteristics. (A) Coronary angiography shows a moderate lesion in the proximal segment of the left circumflex artery, identified as a non-culprit lesion. (B) OCT reveals lipid and fibrous plaques (B1–B3). (C) The calculated OFR measurements are depicted using a color-coded method. (D) Three-dimensional reconstruction of the lumen, with overlaying plaque composition. (E) OFR values are color-coded and displayed on the lumen diameter distribution plot. The most distal OFR value is 0.87.
