Quality control of micro-computed tomography systems

Radiation Protection Dosimetry, 2010
The rapid proliferation of micro-computed tomography (micro-CT) scanners in preclinical small animal studies has created a need for a method on scanner performance evaluation and scan parameter optimisation. The purpose of this study was to investigate the performance of the scanner with a dedicated micro-CT phantom.

Micro-computed tomography for analysis of urinary calculi

Urological Research, 2010
Micro-computed tomographic (micro CT) imaging has become an important tool for the study of urinary stones. The method involves the collection of a series of X-ray pictures of the stone as it is rotated, and the internal structure of the stone is computationally reconstructed from these pictures.

Three-dimensional Bone Imaging: Optical Coherence Tomography versus Micro Computer Tomography

Optical Coherence Tomography and Coherence Techniques IV, 2009
Optical coherence tomography (OCT) and micro-computed tomography (μCT) were applied to a bone sample, a 3×4×4mm cube of fixed substantia spongiosa from an arthritic human hip. Three-dimensional image sets (1.0mm × 0.9mm × 1.6mm) were acquired with both imaging systems for the same volume of interest.

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 ...

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 ...

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.

Assessment of Bone Fracture Healing Using Micro-Computed Tomography

Journal of Visualized Experiments, 2022
Micro-computed tomography (µCT) is the most common imaging modality to characterize the three-dimensional (3D) morphology of bone and newly formed bone during fracture healing in translational science investigations. Studies of long bone fracture healing in rodents typically involve secondary healing and the formation of a mineralized callus. The shape

64 Image optimisation in micro computed tomography

Poster presentation abstracts, 2017
Background Micro Computed Tomography (Micro CT) allows high resolution imaging using a multi-detector X-ray source to give 3D imaging reconstruction of tiny objects at micron resolution. Through a strong industrial collaboration between Great Ormond Street Hospital Children’s Charity and Nikon Metrology Ltd, we installed the world’s first micro CT ...

Characterization of Powders using Micro Computed Tomography

Particle & Particle Systems Characterization, 2011
AbstractMicro computed tomography (μCT) is proposed as a tool for the characterization of powders. Using this technique three dimensional images carrying the whole spatial information on a particular powder can be obtained. After an image analytic separation of the single particles, distributions of geometric characteristics describing size, shape, and

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 ...
