High-definition high-throughput micro-tomography at SPring-8

In SPring-8, the number of micro-tomography experiments is increasing. We adopted a continuous acquisition method and high speed CCD camera for increasing a throughput. Those techniques reduced the measurement time and increased the throughput. The total measurement time for 1800 projections with 2000x1311 pixels projection images was reduced to 20 minutes or less while that of previous system using 'step-and-shoot' method was a few hours. These enable us to image soft materials (tissue) and to do time resolved measurements in three-dimension. The spatial resolution of those systems is around 1 μm and the field of view 1 mm in horizontal direction. Using those systems, more than 30 measurements can be done during one day. It also means that the hundreds gigabytes of data per day is obtained.
