Hierarchical Structure of Bone and Micro-Computed Tomography

2001
Bone is highly complex, with multiple hierarchical levels of structure. Micro-CT has been able to provide much information about the properties of bone at several of these levels at the mid-range of bone's hierarchical structure, and it will continue to provide a valuable tool for further characterizing bone in various conditions and explaining ...

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

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.

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—Current Status and Developments

Annual Review of Biomedical Engineering, 2004
▪ Abstract  The recent rapid increase in interest in tomographic imaging of small animals and of human (and large animal) organ biopsies is driven largely by drug discovery, cancer detection/monitoring, phenotype identification and/or characterization, and development of disease detection methods and monitoring efficacies of drugs in disease treatment.

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

2008
Micro-computed tomography (micro-CT) provides high-resolution three-dimensional (3D) geometry and density information for the analysis of biological materials, and is particularly well-suited for bone research. These detailed 3D data have provided significant insights into issues surrounding bone quality, and the recent advancement of this technology ...

X-ray micro computed tomography in cultural heritage

Analytical Methods, 2020
X-ray micro computed tomography (μCT) can reveal the internal structure of several types of objects by exploiting differences in their X-ray absorption. It can: provide information about the objects' relative composition and density without taking any samples or causing any damage; reveal invisible defects, cracks or damage; show if there are any ...

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 ...
