Development of fully automatic high energy x-ray tomography system at SPring-8 BL28B2

Abstract

At SPring-8 BL28B2, Hoshino et al. developed a CT measurement technique using high-energy x-rays (200keV) to observe internal structures of materials. Combining this with a sample exchange robot, high-def x-ray camera, and SP8-DC computer tech, they automated the process from measurement to image reconstruction. The system captures projection images with a maximum field of view of 48mm x 1.2mm, handling larger specimens by repeated scans and stacking CT images. Measuring a sample with the size of 48mm x 10mm takes about 1.5 hours with the effective pixel size of 3.72um/pixel. Then, transferring the data to SP8-DC is completed within half an hour, and image reconstruction takes approximately 6 hours.
