Bolus-chasing CT Angiography - Catch the Contrast via Control
Intravenous injection of contrast media is required to enhance conspicuity of the vasculature, organs and tumors in CT angiography (CTA) for diagnosis of cardiovascular structures, peripheral vessels and solid organs. The ...
Bioluminescence Tomography - Inner-light, Insight from Infrared
Bioluminescence tomography (BLT) is a molecular imaging modality, which derives a bioluminescent source distribution inside a small animal from external bioluminescent signals. We published the first paper on BLT in 2004 ...
Spiral Cone-beam CT - Successes with Spiral Scans
X-ray computed tomography (CT) is instrumental in medicine, industry and homeland security, which depicts internal structures of an object from its shadows projected in a fan-beam or cone-beam from an x-ray source along a ...
Phase Approximation Model - Approximation Amazingly Accurate
The radiative transfer equation (RTE) well describes the photon propagation but its high computational cost is prohibitive for tomographic imaging. The diffusion approximation (DA) to RTE is the most popular but it only ...
X-ray Grating-based Imaging - Waves Work Wonderfully
Current x-ray imaging is of critical for clinical and pre-clinical applications but it is fundamentally restricted by the attenuation mechanism. X-ray grating-based imaging represents outstanding opportunities and major ...
Fluorescence Tomography - Monitor Malignancy in Mice
Dr. Cui's group at Wake Forest has been investigating a newly discovered innate anticancer immunity in a colony of cancer resistant mice, and already demonstrated that the anticancer activity in the mice stems from the ...
Interior Tomography - Depict with Direct Data
While the conventional wisdom states that the interior problem - to reconstruct a region of interest (ROI) only from projection data through the ROI - does not have a unique solution, in June 2007 we published the first ...
Fast CT Reconstruction - Practical Performance via Parallelization
Parallel computing has been used to solve large-scale problems in many fields. While CT is being developed towards high-resolution, volumetric, dynamic and spectral imaging, datasets become increasingly large, and ...
Axiomatic Imaging Theory - Formulate with Fairness & Fun
There are many imaging systems. Their performance characterization is important for all applications. Various definitions are introduced for quantification of image resolution, which is the ability of an imaging system to ...
Image Warping - Unravel Unevenness into Uniformity
Demonstrations of anatomical systems computationally extracted from spiral CT images and then unraveled onto a plane in vivo to ultimately conceive 3D individualized models.
