A-line classification results in en face (θ,z) view. Panels in columns are (left) ground truth, (center) results obtained using Deeplab v3+, and (right) results obtained using SegNet. Red, green, and blue indicate fibrocalcific, fibrolipidic, and other A-line classes, respectively. White is the guidewire. Results are from one test fold data, including five VOIs (479 image frames). Cardiologists scored lesion results by performing a clinical score assessment (CSA), with the following rating scale: 1: strongly disagree, 2: disagree, 3: unsure, 4: agree, and 5: strongly agree. All three cardiologists agreed that the automated results will not change clinical decision making.
