    The study assessed ultrasound-specific augmentation to enhance segmentation of ovarian tumors in B-mode and contrast-enhanced ultrasound images.

  • 2

    A lightweight Residual U-Net was used to compare performance with and without combined ultrasound-specific augmentation.

  • 3

    Combined augmentation improved segmentation metrics on contrast-enhanced ultrasound, including Dice and intersection over union.

  • 4

    Despite improvements, segmentation performance on contrast-enhanced ultrasound remained suboptimal, with over half of cases still below a Dice of 0.5.

  • 5

    The findings suggest that training-distribution design can enhance robustness against modality shifts without increasing inference-time complexity.
