Popis:	Impulse tomography analysis is a non-destructive method that enables the visualization of the interior of the wood of trees through the passage of mechanical waves, making it possible to perform a preliminary examination and notice the presence of defects in the wood. ARBOTOM impulse tomography was used to analyze the wood of trees of Tectona grandis, located in Caceres, State of Mato Grosso, Brazil. It was possible to detect the presence of distinct zones in the wood by varying the speed of the wave mechanics indicated by different colored areas in tomography image. Possibly, these color differences are attributed to variations in wood density and moisture content.
