OSCAR method reconstructs 3D vertebral anatomy from ultrasound

Researchers have developed OSCAR, a novel method for reconstructing 3D vertebral anatomy from ultrasound images. This approach utilizes occupancy-based shape completion and a Neural Implicit Representation (NIR) to accurately model both spatial occupancy and acoustic interactions. By incorporating acoustic parameters, OSCAR can infer unseen regions without requiring explicit anatomical labels during inference, outperforming existing methods by 80% in HD95 score. The system has been validated on both simulated and phantom ultrasound images, demonstrating robust generalization and accurate reconstruction of occluded anatomy. AI

IMPACT This method could improve precision in minimally invasive spine interventions by enabling more accurate 3D anatomical reconstruction from ultrasound.
