MicroCT reveals domesticated rice (Oryza sativa) within pottery sherds from early Neolithic sites (4150–3265 cal BP) in Southeast Asia

Scientific Reports, 2017
Rice (Oryza sativa) was domesticated in the Yangtze Valley region at least 6000–8000 years ago, yet the timing of dispersal of domesticated rice to Southeast Asia is contentious.

Applications of X-ray computed tomography in textile field

Fushe yanjiu yu fushe gongyi xuebao, 2022
Traditional optical imaging technique used as an analysis method for microstructure can only observe surface and can't achieve 3D characterization of the material interior, which greatly limits its application in textile field.

Terahertz Computed Tomography of NASA Thermal Protection System Materials [PDF]

, 2012
A terahertz axial computed tomography system has been developed that uses time domain measurements in order to form cross-sectional image slices and three-dimensional volume renderings of terahertz-transparent materials. The system can inspect samples as

X-ray Fluorescence Computed Tomography (XFCT) Imaging with a Superfine Pencil Beam X-ray Source

Photonics, 2021
X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique that can be used to sense different elements or nanoparticle (NP) agents inside deep samples or tissues. However, XFCT has not been a popular molecular imaging tool because it

X-ray luminescence computed tomography using a focused X-ray beam

, 2017
Due to the low X-ray photon utilization efficiency and low measurement sensitivity of the electron multiplying charge coupled device (EMCCD) camera setup, the collimator based narrow beam X-ray luminescence computed tomography (XLCT) usually requires a ...
