Small, low-field magnetic resonance imaging devices and methods are developed and evaluated, which aim to image xylem water content changes in trees in vivo, and to monitor and quantify xylem embolism formation due to drought stress in particular. Dedicated combinations of purpose-built imaging hardware and software are introduced and verified in dry-down experiments on young beech and spruce trees. Novel approaches to process magnetic resonance images for obtaining xylem vulnerability curves are presented.
