New framework improves CT-US image registration with anatomical priors

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for deformable registration between ultrasound (US) and computed tomography (CT) imaging. This method incorporates anatomical priors from CT to improve alignment, particularly in scenarios where soft tissue deformation occurs during procedures. The system uses a sinusoidal implicit neural representation (SIREN) for deformable transformation estimation, with tissue stiffness approximated from CT-based HU values to guide the deformation process. Additional constraints capture the physics of probe contact and beam geometry, resulting in improved alignment over rigid initialization and classical deformable methods. AI

IMPACT This research could enhance precision in medical interventions by improving the alignment of different imaging modalities.

    Deformable CT-US Registration via Anatomy-Aware Implicit Neural Representations

    arXiv:2610.08419v1 Announce Type: new Abstract: Slice-to-volume registration between ultrasound (US) and preoperative computed tomography (CT) imaging would enhance many minimally invasive interventions, for example by locating soft tissue structures intra-operatively that are di…
