Description
Synchrotron radiation X-ray computed tomography (XCT) datasets were acquired at SPring-8 for a fine Bennu sample using multiple imaging conditions. This bundle includes three XCT image collections: absorption-contrast XCT acquired at 7.0 keV, absorption-contrast XCT acquired at 7.35 keV across the Fe K-edge, and phase-contrast XCT acquired at 8.0 keV. The three datasets were spatially registered and used for RGB-CT visualization to enable quantitative discrimination of mineral phases. Instrument metadata documenting acquisition, reconstruction, and CT-value mapping parameters are provided for each dataset. The XCT imaging was performed on Febuary 19, 2025.
