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

open access: yesScientific 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

open access: yesFushe 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.

Nondestructive 3D Image Analysis Pipeline to Extract Rice Grain Traits Using X-Ray Computed Tomography

open access: yesPlant Phenomics, 2020
The traits of rice panicles play important roles in yield assessment, variety classification, rice breeding, and cultivation management. Most traditional grain phenotyping methods require threshing and thus are time-consuming and labor-intensive ...
