Micro-Computed Tomography to Evaluate Bone Remodeling and Mineralization

2001
It is a well-known fact that denser materials appear brighter in radiographic images than less dense materials. The reason for this is that denser materials absorb more photons.

The dynamic micro computed tomography at SSRF

Journal of Instrumentation, 2018
Synchrotron radiation micro-computed tomography (SR-μCT) is a critical technique for quantitative characterizing the 3D internal structure of samples, recently the dynamic SR-μCT has been attracting vast attention since it can evaluate the three-dimensional structure evolution of a sample. A dynamic μCT method, which is based on monochromatic beam, was

Rotary shear experiments under X-ray micro-computed tomography

Review of Scientific Instruments, 2017
A rotary shear apparatus (ERDμ-T) was designed, assembled, and calibrated to study frictional behavior. We paired the apparatus with X-ray micro-computed tomography (μCT) to inspect in situ and in operando deformation of the tested specimen. This technology allows us to observe how two rough surfaces interact and deform without perturbing the ...

Micro‐computed tomography: an alternative method for shark ageing

Journal of Fish Biology, 2012
Micro‐computed tomography (microCT) produced 3D reconstructions of shark Carcharhinus brevipinna vertebrae that could be virtually sectioned along any desired plane, and upon which growth bands were readily visible. When compared to manual sectioning, it proved to be a valid and repeatable means of ageing and offers several distinct advantages over ...

Micro–Computed Tomography Assessment of Apical Accessory Canal Morphologies

Journal of Endodontics, 2016
The morphologic features of accessory canals (ACs) were investigated by using micro-computed tomography technique with a centerline fitting algorithm.Ninety-three 3-mm-long apical root segments with unobstructed ACs were scanned by micro-computed tomography at 2.5-μm scanning resolution.

Microstructure study of normal lunates with micro-computed tomography

Journal of Huazhong University of Science and Technology [Medical Sciences], 2017
In order to study the microstructure characteristics of normal lunate bones, eight fresh cadaver normal lunates were scanned with micro-computed tomography. High-resolution images of the micro-structure of normal lunates were obtained and we analyzed the nutrient foramina. Then nine regions of interest (ROI) were chosen in the central sagittal plane so

Micro-computed tomography in caries research

2007
Over the past years there have been attempts to improve the development of techniques for caries detection and quantification. The demand for a non-destructive method has encouraged the use of micro-CT in studies of enamel de-remineralization. Our contribution to this development were presented in this work by evaluating the limitations of the method ...

Micro Computed Tomography in the Biomedical Sciences

2006
With recent developments in micro Computed Tomography (CT), biomedical researchers have begun to explore the potential of this radiographic approach to microscopy. The key advantage of micro CT includes its ability to rapidly and nondestructively provide three dimensional analysis at high resolutions.

Micro‐computed tomography: a new tool for experimental endodontology

International Endodontic Journal, 1999
Aim Micro‐computed tomography (MCT) using cone‐beam geometry is a method of producing true 3D images of the structure of small samples. A prototype MCT unit was adapted for imaging teeth to examine whether it could be used to quantify the instrumentation of root canals.Methodology Ten mandibular first molar teeth that had intact crowns and fully formed

Cone-beam micro computed tomography dedicated to the breast

Medical Engineering & Physics, 2016
We developed a scanner for micro computed tomography dedicated to the breast (BµCT) with a high resolution flat-panel detector and a microfocus X-ray tube. We evaluated the system spatial resolution via the 3D modulation transfer function (MTF). In addition to conventional absorption-based X-ray imaging, such a prototype showed capabilities for ...
