X-ray micro-computed tomography (XμCT) was used to explore the decomposed structure of conifer and angiosperm wood after colonization by soft-rot fungi. The visualization of degradation features of soft-rot decay was challenging to achieve through XμCT. Difficulties in visualization emerged due to a decreased grayscale contrast (i.e. X-ray density) of the degraded wood. Nevertheless, we were able to image fungal-induced cell deformations in earlywood and cavities in the thick wall of latewood cells in three-dimensions (3D). Unlike the organic wood material, the higher X-ray density of inorganic deposits, identified as mainly calcium-based particles by energy-dispersive spectroscopy, allowed a facilitated 3D survey. The visualization of inorganic particles in 3D revealed a localized distribution in certain cells in conifer and angiosperm found mostly in earlywood.

X射线显微计算机断层扫描（XμCT）用于探索软腐真菌定植后针叶树和被子植物木材的分解结构。通过 XμCT 实现软腐烂退化特征的可视化具有挑战性。由于灰度对比度降低（即降解木材的 X 射线密度）。尽管如此，我们还是能够在三维 (3D) 中对早材中真菌诱导的细胞变形和晚材细胞厚壁中的空腔进行成像。与有机木质材料不同，无机沉积物的更高 X 射线密度（通过能量色散光谱确定为主要是钙基颗粒）可以促进 3D 调查。无机颗粒的 3D 可视化揭示了针叶树和被子植物中某些细胞的局部分布，这些细胞主要存在于早木中。
