Abstract: Highlights•We construct a multi-modality ovarian tumor ultrasound dataset with 2d-ultrasound and CEUS images.•We are the first to propose a method for the cross-domain ovarian tumor segmentation task.•Domain shift problem will be eased by extracting domain-distinct and domain-universal features.•2d-ultrasound trained model has the adaptation capability for CEUS images.
