USDA plant biologist Andrew McElrone is using high resolution computed tomography – a type of cat scan similar to the medical imaging diagnostic system – to cruise through plant veins and vessels to better understand grapevines’ water transport system.
The research is conducted on live and dry grapevines at the Lawrence Berkeley National Laboratory. Like in medicine, each cat scan produces numerous digital slices of grapevine, which are stacked on top of each other using special engineering software to reconstruct the system.
“We can then spin the images around into various orientations, moving through individual vessels,” McElrone said.
