RESUMOA microtomografia computadorizada de raios X (microCT) é uma das mais avançadas técnicas de análise não destrutiva e possibilita a reconstrução da estrutura anatômica da madeira e de seus produtos. O trabalho aplicou a microCT na análise da anatomia da madeira de Amburana cearensis e de Pinus sp. A microCT possibilitou a obtenção de imagens da estrutura macro e microscópica da madeira das duas espécies, permitindo a sua caracterização, descrição e comparação com a da literatura. As vantagens da microCT, em relação à confecção de lâminas histológicas, mantendo a integridade das amostras de madeira, painéis, carvão, papéis, etc. são discutidas.Palavras-chave: microtomografia de raios X, Amburana cearensis, Pinus sp. X-ray Microtomography to Anatomical Characterization of Softwood and HardwoodABSTRACT X-ray computed microtomography (microCT) is one of the most advanced non-destructive techniques enabling the reconstruction of wood anatomical structure and its products. This work applied the microCT to the analysis of wood anatomy of Amburana cearensis and Pinus sp. Through microCT it was possible to obtain images of the macro and microscopic wood structure of the two species, followed by the characterization, description and comparison to the literature. The advantages of microCT are discussed in relation to the preparation of histological slides, providing the integrity of wood, panels, charcoal, paper samples, etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
