Incorporating uncertainty awareness into deep learning-based diffeomorphic lung image registration significantly improves accuracy, particularly in cases with large deformations between inspiratory and expiratory lung volumes, enabling more reliable and robust registration for both forward (TLC to FRC) and inverse (FRC to TLC) transformations.
標準的なベンチマークの限界を克服するため、大規模で多様なデータセットと包括的な評価手法を用いた医療セグメンテーションAIのためのベンチマーク「Touchstone」を開発し、その有効性を示した。
AtlasSeg, a novel deep learning model, leverages gestational age-specific atlas priors and a dual-U-Net architecture with multi-scale attentive fusion to significantly improve the accuracy of cortical segmentation in fetal brain MRI, outperforming existing state-of-the-art methods.
本稿では、複雑な気道構造を正確にセグメント化するため、マルチスケールネスト型 Residual UNet(MNR-UNet)と重み付きBreakage-Aware Loss(wBAL)を組み合わせた新しい3段階セグメンテーション手法を提案する。
Strategically selecting a combination of synthetic tumor sizes and generating synthetic tumors with precise boundaries significantly improves the accuracy of deep learning-based pancreatic tumor segmentation models.
This research aims to investigate the relationships between microstructural and macrostructural features of the cervical spinal cord in a healthy population using quantitative MRI analysis, and to develop a deep learning-based segmentation framework for accurate measurement of macrostructural characteristics.
Leveraging diverse pathological clues, including segmented regions, entities, and report themes, to build fine-grained cross-modal representations and seamlessly transfer them to enhance the quality of generated brain CT reports.
A cascading refinement CNN model, MS-CaRe-CNN, can semantically segment the left and right ventricle, healthy and scarred myocardial tissue, as well as edema from multi-sequence cardiac MRI data, enabling accurate assessment of myocardial viability.
