在春八，微型层析成像实验的数量正在增加。为了提高吞吐量，我们采用了连续采集的方法和高速的CCD摄像机。这些技术缩短了测量时间，提高了吞吐量。对于具有2000×1311像素投影图像的1800个投影，总测量时间减少到20分钟或更短，而以前的系统使用分步拍摄的方法只需几个小时。这使我们能够对软材料(组织)成像，并在三维中进行时间分辨率测量。这些系统的空间分辨率约为1μm，水平方向视场约为1 mm。使用这些系统，一天可以进行30多次测量。这也意味着每天获得数百GB的数据。
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 2000×1311 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.
