From: Reduced spatial resolution MRI suffices to image and quantify drought induced embolism formation in trees

Fig. 3

A*T2 product maps of xylem embolism formation in spruce (a) and beech (b). Images were acquired with matrix sizes of 32 × 32, 64 × 64 and 128 × 128 pixels, resulting in pixel sizes of 0.59 × 0.59, 0.30 × 0.30 mm and 0.15 × 0.15 for spruce and 0.72 × 0.72, 0.36 × 0.36 and 0.18 × 0.18 mm for beech). Below the parameter maps desiccation time and water potential (WP) are shown. The concomitant water content and T2 images are provided in Additional file 2. Imaging continuously allowed for resolving finer spatio-temporal details of embolism formation. In (c) the first emboli forming in spruce are shown, in panel (d) the completion of xylem dry-down in beech. In all panels (ad), the difference in image intensity between the first and the last image is shown in the rightmost position (\({\Delta }_{-}\))
