In our specific application, a powder is transferred through a pipe to a reaction container and the objective is to measure the mass concentration at different cross section levels inside the container so that a spatial distribution can be estimated in dynamic conditions, i.e. powder flow.X-ray computed tomography (CT) is a non-invasive and non-destructive technique answering the requirements of our problem. A specific mechanical setup was built and because of space and mechanical constraints a special acquisition geometry was used, which implied the adaptation of the CT reconstruction algorithm. %G English %L cea-01834542 %U https://cea.hal.science/cea-01834542 %~ CEA %~ DRT %~ LIST
