Multi-modal real-time imaging modalities tracking individual micro-agents and high-density swarms deep within opaque living tissue.
Bi-plane X-ray systems sample micro-robot positions at 30 fps using low radiation dosages. Image-processing filters isolate the high-contrast magnetic cores from skeletal and vascular backgrounds.
For micro-catheter tips, forward-looking OCT probes deliver 10-micrometer axial resolution, visualizing vessel wall micro-tears and guiding the micro-swarm through narrow bifurcation angles.
