A General Formula for Fan-Beam Lambda Tomography

open access: yesInternational 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

open access: yesNeoplasia: 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.

Bronchial Circulation Angiogenesis in the Rat Quantified with SPECT and Micro-CT [PDF]

open access: yes, 2008
Introduction As pulmonary artery obstruction results in proliferation of the bronchial circulation in a variety of species, we investigated this angiogenic response using single photon emission computed tomography (SPECT) and micro-CT.

Microcomputed tomography–based characterization of advanced materials: a review

open access: yesMaterials Today Advances, 2020
Micro-computed tomography (CT) is an X-ray tomography technique with (sub)micron resolution, typically using an X-ray tube with cone-beam geometry as a source and a rotating sample holder.
