Real-Time Self-Prompting Adaptation of a Foundation Model for Fetal Ultrasound

Adapted the Segment Anything (SAM) foundation model to be self-prompting for fetal ultrasound, achieving clinical-grade precision with real-time inference. Deployed in a robotic prototype, the system reduced manual scanning time by over 85%, enabling high-throughput prenatal screening and drawing strong interest from clinicians at the XVIII Clinical Ultrasonography in Practice (CUSP) conference.
