abstract = {The application of non-invasive imaging technologies has
had a large impact on the study of plant water relations.
Magnetic Resonance Imaging (MRI) has made it possible to
image the presence of water or the appearance of emboli in
the xylem, or to measure, visualize and quantify flow.
However, due to the cost, size and specialized nature of the
MRI equipment, so far the method has only been applied to
plants by a few laboratories world-wide. To make the method
more accessible, but also make it available for use in the
greenhouse or field, we constructed a basic, mobile MRI
imager for plants, maximizing for making it cheap and simple
to use.At the basis of this work was the construction of a
mobile 0.25 T, 45 mm gap, C-shaped permanent magnet with a
weight of about 16 kg, suitable for MR imaging of objects up
to 20 mm diameter. The magnet was fitted with a set of
custom built plane-parallel imaging coils, designed for
maximum field of view and image resolution, while still
offering open access for plant stems. Using a permanent
magnet is beneficial due to low purchase and running costs,
since neither any power nor liquid gases are required to run
it.In a first demonstration experiment we investigated the
effect of drought stress on young spruce and beech trees
during a 40 day dry down experiment. Considering the
simplicity of the setup and the small size of the magnet,
surprisingly highly resolved images could already be
acquired with the very first protoype. By means of this data
that was obtained weekly over the whole dry down period,
insights could be gained on where emboli occur first in the
stems of the two species.},
