首次通过X射线层析成像研究了三维液体泡沫。该方法能够观察大量气泡（数千个），从而提取泡沫结构的重要统计特征。本文介绍了实现这一目的所遵循的连续步骤：图像采集、图像处理和数据提取。这个全球性的过程可以自动化，但我们强调的两个参数，可以由用户任意设置的选择的重要性。第一个是最小气泡尺寸的截止值，第二个涉及对湿泡沫模糊的气泡邻居的定义。我们在这里讨论的后果，这两个选择的特点，如平均数的泡沫面。
3D liquid foams are investigated for the first time through X-ray tomography. This method enables to observe large number of bubbles (several thousands), and hence, to extract significant statistical characteristics of the foam structure. This article presents the successive steps we followed to achieve this purpose: image acquisition, image processing and data extraction. This global procedure can be automatised, but we emphasize the importance of the choice of two parameters which can be arbitrarily set by users. The first one is the cut-off value for the size of the smallest bubbles, the second deals with the definition of the neighbors of a bubble which is ambiguous for wet foams. We discuss here the consequences of these two choices on characteristics such as the average number of faces of bubbles.
