Picus Sonic Tomograph (Tree Ultrasound)
The Picus Sonic Tomograph is an instrument used for measuring decay and the structural integrity of trees. The non-invasive detection device maps the internal wood density of a tree being tested producing a two dimensional computer generated image that is clear and simple to understand.
The system measures the velocity of sound waves passing through a tree and allows our Arborists to accurately detect the location and severity of decay in a trunk or branch of a tree. The technology can help professionals and tree owners make accurate and informed decisions about trees before part or entire tree failure occurs.
Benefits of Picus Sonic Tomograph are:
• Easy to use - even close to ground level and on large irregular shaped trees
• Instant on-site results
• Improved information for long-term planning and management of trees
• See ‘inside’ the tree to greatly improve assessment
• Colour images are easy to explain to customers
• Simply the best decay detection/evaluation device currently available
Example of a recent analysis:
Test results of the example tree
- 23% of the test area is sound wood (brown areas).
- 10% of the test area is altering wood i.e. wood being altered by fungal decay (green area).
- 67% of the test area is occupied by the active fungus (pink and blue areas).
- The tree had extensive decay and was regarded as a high hazard despite the stable outer appearance.
This tree was located within the Sydney CBD and had a long history of below ground disturbances. It had extensive decay within its roots and trunk base and was a high risk to persons and properties. Despite the stable outer appearance, the tree was removed.
