Abstract A new method to measure and quantify the 3D mineralogical composition of particulate materials using X-ray computed micro-tomography (CT) is presented. The part a workflow designed standardize analysis particles based on their microstructures without need segment individual classes or grains. Classification follows decision tree with criteria derived from particle histogram parameters ...

This article describes a quantitative evaluation of visualizing small vessels using several image reconstruction methods in computed tomography. Simulated vessels with diameters of 1-6 mm made by 3D printer was scanned using 320-row detector computed tomography (CT). Hybrid iterative reconstruction (hybrid IR) and model-based iterative reconstruction (MBIR) were performed for the image reconstr...

objectives: accurate localization of the inferior alveolar canal (iac) is extremely important in some dental treatments. anatomical variation of the canal means that it can be difficult to locate. the purpose of this study was to assess the relationship of the gonial angle (ga) size and iac position using cone beam computed tomography (cbct). materials and methods: in this in vitro study, 61 dr...
