【 摘 要 】

Measurement conditions in X-ray phase tomography using a grating interferometer were evaluated to achieve fast measurements toward 4D X-ray phase tomography for biological samples. X-ray phase tomographic images obtained from different exposure time and the number of projections were examined to determine required statistics for high density resolution while keeping a fast measurement. Application of a high-efficiency fiber-coupled X-ray imaging detector to X-ray phase tomography was also discussed from a comparison between the fiber-coupled and lens-coupled detectors.
