abstract = {Positron emitters such as 11C, 13N and 18F and their
labelled compounds are widely used in clinical diagnosis and
animal studies, but can also be used to study metabolic and
physiological functions in plants dynamically and in vivo. A
very particular tracer molecule is 11CO2 since it can be
applied to a leaf as a gas. We have developed a Plant
Tomographic Imaging System (PlanTIS), a high-resolution PET
scanner for plant studies. Detectors, frontend electronics
and data acquisition architecture of the scanner are based
on the ClearPETTM system. The detectors consist of LSO and
LuYAP crystals in phoswich configurationwhich are coupled to
position-sensitive photomultiplier tubes. Signals are
continuously sampled by free running ADCs, and data are
stored in a list mode format. The detectors are arranged in
a horizontal plane to allow the plants to be measured in the
natural upright position. Two groups of four detector
modules stand face-to-face and rotate around the
field-of-view. This special system geometry requires
dedicated image reconstruction and normalization procedures.
We present the initial performance of the detector system
and first phantom and plant measurements.},
