Abstract: Highlights•An efficient method obtains the most accurate discontinuous deformable registration.•Motion Separability quantifies the upper limit of predicted motions’ discontinuity.•Motion-Separable structure is used for a better motion separability.•Multi-Head mask is regressed to disentangle the motions across different organs.•Confidence weight is estimated to refine the predicted motions.
