Log scanning to determine internal characteristics to maximize lumber value has been a long-term goal of the sawmilling industry. Juvenile wood is wood formed in southern pine trees during the first 10 years of growth. Juvenile wood is characterized by wood with high moisture content and that undergoes a high degree of longitudinal shrinkage during kiln drying. This shrinkage results in large amounts of warp that produce lumber degrade and very high value loss. Detection of juvenile wood prior to sawing logs will allow application of sawing patterns and drying procedures that result in reduced influence on the final lumber value. Our research tested EIT scanning with brush electrodes to determine the potential for detecting juvenile wood in green southern pine logs. EIT and computed tomography (CT) images were compared to determine that juvenile wood could be detected with acceptable.
