Micro-Ultrasound-Specific Adaptation of the Foundation Model for Prostate Segmentation
Micro-ultrasound (microUS) provides high-resolution visualization of the prostate for interventional procedures; however, the scarcity of annotated datasets limits the development of robust automated segmentation methods. This study leverages a foundation-mod...

Text-Guided Segmentation of Cardiac Substructures on Contrast-Enhanced CT
Dose sparing of cardiac substructures has the potential to improve thoracic radiotherapy outcomes beyond conventional whole-heart dose-volume metrics. However, manual delineation of numerous substructures is prohibitive, limiting the availability of high-qual...

CBCT Liver and Lesion Segmentation Using CT Fine-Tuned Foundation Model for CBCT-Guided Radiotherapy
Cone-beam CT (CBCT) is integral to modern radiotherapy workflows; however, limited soft-tissue contrast and imaging artifacts restrict its quantitative use, particularly for online auto-segmentation in CBCT-guided adaptive radiotherapy. Models pretrained on c...

Cross-Modality Transfer of a CT–Fine-Tuned Foundation Model for Prostate and Lesion Segmentation on MRI
Prostate MRI is increasingly used in modern radiotherapy, but compared with CT, large-scale MRI datasets remain limited for fine-tuning foundation models. This study investigates the cross-modality transferability of a CT–fine-tuned foundation model to prosta...
