A boundary regularized deep convolutional encoder-decoder network (ConvEDNet) is developed in this study to address the difficult anatomical layer parsing problem in the noisy Automated Whole Breast Ultrasound (AWBUS) images. To achieve better network initialization, a two-stage adaptive domain transfer (2DT) is employed to land the VGG-16 encoder on the AWBUS domain with the bridge of network training for AWBUS edge detector. The knowledge transferred encoder is denoted as VGG-USEdge. To further augment the training of ConvEDNet, a deep boundary supervision (DBS) strategy is introduced to regularize the feature learning for better robustness to speckle noise and shadowing effect. We argue that simply counting on the image context cue, which can be learnt with the guidance of label maps, may not be sufficient to deal with the intrinsic noisy property of ultrasound images. With the regularization of boundary cue, the segmentation learning can be boosted. The efficacy of the proposed 2DT-DBS ConvEDNet is corroborated with the extensive comparison to the state-of-the-art deep learning segmentation methods. The segmentation results may assist the clinical image reading, particularly for junior medical doctors and residents and help to reduce false-positive findings from a computer-aided detection scheme.
