dc.description.resumoThis paper deals with the determination of cross-sectional pieces of wood using acoustic tomography by means of the physical principle of emission and acoustic waves path. In order to evaluate this method three wooden samples were tested with the Acoustic Tomography Arbor Sonic 3D equipment. The objective was to verify the influence of the arrangement of the transducers in diametric portion of the logs and along its longitudinal direction, through the quality of information provided on its phytosanitary status. A visual analysis of the images generated by the software and subsequently an overlay of the imageswere made and the overlapping images were compared to the photographic images. The results showed a variation of images according to the arrangement of the transducers in the diametral portion and the overlapping provided a representative image of the real state of the logs. Regarding the arrangement along the longitudinal axis, it was possible to determine the phytosanitary status of the entire log. It was possible to conclude that the position of the transducers influences the acoustic tomography quality and that the proposed method enables to determine a more robust image to assess the levels of degradation of the wooden parts.pt_BR
