The PiCUS Sonic Tomograph is used for tree risk assessments in order to measure the thickness of the residual wall of trees with internal defects such as cavities or decay non-invasively. Most often the PiCUS sonic tomograms are recorded near ground level of trees. However, acoustic tomograms also reveal important safety information about the breaking risk near branch wounds and above ground cavities.
The new PiCUS 3 can use up to 12 sensors, but the amount of measurement points are endless. This means that no tree is too large to 'scan'.
Using PiCUS creates a 2-dimensional 'scan' and presents information on existance of rot and level of stability. By 'scanning' the tree in different heights we can produce a 3-D image of the stem.
