Architecture of U-Net CNN model used to segment the radiographic images. Encoder of the model had the VGG-16 architecture and its initial weights were pooled from a model pre-trained on the ImageNet database. The output of the model will initially have three channels (in AP model) or two channels (in cross-table lateral model). An argmax function will change this output to a one-channel 512×512-pixel mask, that is then used for image processing.
