However, there is no abdominal and retroperitoneal organs atlas framework for multi-contrast CT.
While deep learning has achieved significant advances in accuracy for medical image segmentation, its benefits for deformable image registration have so far remained limited to reduced computation times.
AGs can be easily integrated into standard CNN models such as VGG or U-Net architectures with minimal computational overhead while increasing the model sensitivity and prediction accuracy.

We propose a novel attention gate (AG) model for medical imaging that automatically learns to focus on target structures of varying shapes and sizes.

However, in most recent and promising techniques such as CNN based segmentation it is not obvious how to incorporate such prior knowledge.
