Abstract

X-ray computed tomography (CT) technology was applied for log nondestructive testing. The heartwood and sapwood of Larix gmelinii (Dahurian Larch) were scanned by CT system. The appropriate mathematical formulas between wood density and CT number were established for heartwood and sapwood respectively, because of the close relationship between wood density and CT number. The formulas between moisture content and CT number for heartwood and sapwood were built through experiment. The results indicate that though the differences of density and moisture content between heartwood and sapwood of L. gmelinii were not obvious, heartwood and sapwood had different formulas of forecasting wood density and moisture content by CT. The fitted relationships were very strong (coefficient of determination R² > 0.94).
