Previous methods of decay detecting were invasive to the tree, i.e. increment bores created extensive damage to trees tested. The PICUS system is virtually totally non-invasive. The PICUS system only uses small nails to penetrate the bark to make contact with the timber.I have been working with the Picus sonic decay detection system for 10 years. During this period I came to realise that a major issue with analysing the resultant tomographic image is assessing areas of the images accurately. So I have devised an easy method to give results accurately and concisely. I felt it best to convey my system using video capture for your information. Check out this link: Tomograph image analysis
The Picus system presently provides a global calculation. My more detailed analytical method means that specific chosen areas can be selected. These details can easily be included in a report proving a comprehensive study of the tomographic image. It would appear that too often the Picus image is used to justify Arboricultural recommendations some have not been analysed in depth.
As a tree manager I am sure that you regularly have to consider Picus test reports. This system can easily be used on the desktop. I am willing to share my analysis techniques with you, for your use free of charge. Of course should you be in need of any Picus testing services please do not hesitate to contact me.
