Abstract
In tree sciences computerized tomography allows the quantitative determination of the locally varying absorption coefficients for penetrating radiation within a thin slice of the trunk.
The tomogram shows not only hollows, rot, knots and other defects but also the distribution of water in the invisible interior of the stem.
The tomogram shows not only hollows, rot, knots and other defects but also the distribution of water in the invisible interior of the stem.
Portable systems were used in tree-care and in forestry sciences to obtain information about decay, checks, heartwood formation and moisture content, for the detection of interior decay by fungi and its spread in a horizontal and vertical direction, for determining sapwood area dependent on fertilization, for evaluating development and treatment of tree wounds and for studying the influence of resin tapping on the water supply of pines.
