Due to imaging artifacts and low signal-to-noise ratio in ultrasound images,
automatic bone surface segmentation networks often produce fragmented
predictions that can hinder the success of ultrasound-guided computer-assisted
surgical procedures. Existing pixel-wise predictions often fail to capture the
accurate topology of bone tissues due to a lack of supervision to enforce
connectivity. In this work, we propose an orientation-guided graph
convolutional network to improve connectivity while segmenting the bone
surface. We also propose an additional supervision on the orientation of …
