Imagine an intelligent microscopic worm that could painlessly crawl through blood vessels, mapping every branch and passage. Such a creature could guide brain surgeons cutting out cancerous growths, or cardiologists searching for narrowed arteries. While no such thing exists in the real world, computer scientists at SFU have created artificial software animals that do travel the complex tree-like vessels in 3D medical volume images from CAT scans or MRIs (Magnetic Resonance Images). What’s more, these virtual creatures can navigate more than just blood vessels. They can map out complicated networks of nerves, or air passages in lungs and similar complex branching systems in other organs.
