Stacked microvascular imaging data preprocessing and designing a convolutional neural network model. A Stacked microvascular image generation. Stacked microvascular images generated by accumulating the high-sensitivity Doppler mode called high-definition color for a few seconds can depict many intrahepatic vessels without losing their continuity. To avoid artifacts, 200 × 300 pixels were cropped from the Doppler Region-of-Interest. B Convolutional neural network model construction. The cropped stacked microvascular images were learned by ResNet50
