Interior micro‐CT with an offset detector [PDF]
Medical Physics, 2014 The size of field-of-view (FOV) of a microcomputed tomography (CT) system can be increased by offsetting the detector. The increased FOV is beneficial in many applications. All prior investigations, however, have been focused to the case in which the increased FOV after offset-detector acquisition can cover the transaxial extent of an object fully ...

Temporal and spectral imaging with micro‐CT [PDF]
Medical Physics, 2012 Purpose:Micro‐CT is widely used for small animal imaging in preclinical studies of cardiopulmonary disease, but further development is needed to improve spatial resolution, temporal resolution, and material contrast. We present a technique for visualizing the changing distribution of iodine in the cardiac cycle with dual source micro‐CT.Methods:The ...

Local ROI Reconstruction via Generalized FBP and BPF Algorithms along More Flexible Curves
International Journal of Biomedical Imaging, 2006 We study the local region-of-interest (ROI) reconstruction problem, also referred to as the local CT problem. Our scheme includes two steps: (a) the local truncated normal-dose projections are extended to global dataset by combining a few global low-dose

Micro-CT imaging of Randall’s plaques [PDF]
Urolithiasis, 2014 Micro-computed tomographic imaging (micro-CT) provides unprecedented information on stone structure and mineral composition. High-resolution micro-CT even allows visualization of the lumens of tubule and/or vessels within Randall's plaque, on stones or in papillary biopsies, thus giving a non-destructive way to study these sites of stone adhesion. This

A General Formula for Fan-Beam Lambda Tomography
International Journal of Biomedical Imaging, 2006 Lambda tomography (LT) is to reconstruct a gradient-like image of an object only from local projection data. It is potentially an important technology for medical X-ray computed tomography (CT) at a reduced radiation dose.

High-Resolution X-ray Microtomography for the Detection of Lung Tumors in Living Mice
Neoplasia: An International Journal for Oncology Research, 2004 In the present study, the feasibility of applying highresolution microtomography (micro-CT) for the detection of lung tumors was investigated in live mice at an early and more advanced stage of tumor development.

Micro-computed tomography for natural history specimens: a handbook of best practice protocols
European Journal of Taxonomy, 2019 Micro-computed tomography (micro-CT or microtomography) is a non-destructive imaging technique using X-rays which allows the digitisation of an object in three dimensions.

Small animal micro-CT colonography [PDF]
Methods, 2010 Microcomputed tomography colonography (mCTC) is a new method for detecting colonic tumors in living animals and estimating their volume, which allows investigators to determine the spontaneous fate of individually annotated tumors as well as their response to chemotherapeutics.
