Tomography and laminography applications in paleontology and plant biology at the Advanced Photon Source.

X-ray tomography is a non-destructive detection technique for imaging objects such as biological specimens. Unlike histological techniques, x-ray tomography can section a specimen numerically rather than physically. Compared to x-ray tube based microCT, synchrotron radiation based microCT (SRμCT) has unmatchable advantages in terms of spatial resolution and data acquisition speed. Synchrotron radiation based laminography (SRLam) is an alternative to SRμCT that is suitable for laminar specimens, such as permineralized structures in rock matrix (e.g., coal ball slice). For fossils that are thin on one dimension but extended on another two dimensions, laminography is an ideal tool to obtain 3-dimensional anatomical information. SRμCT has been recently employed in studies of fossil materials. At the Advanced Photon Source (APS) of Argonne National Laboratory, the micro-tomography beamline 2BM has been optimized and several accessory techniques have been developed for fossil and living plant imaging. In this talk, the results with both techniques will be presented.
