摘要
A given fast X-ray tomograph with two parallel measuring planes is used for spatially resolved measurements of flow velocities by design. Now it is to be extended to time-resolved measurements avoiding any additional technical effort. But the spacing between the planes is too big. Thus, an additional indirect measuring plane is defined utilizing radiation which propagates between the regular planes during the tomographic scan. This indirect plane is close enough to one of the regular planes. A practical example illustrates the mode of measurement using the new method.
