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 ...
Spiral CT of the Temporal Bone
Maximum image resolution with commercial spiral CT scanners is inadequate to define clearly the anatomical features and electrode positions within this intricate, 3D space. The objective of this research was to develop ...
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 ...
TIM-OS: A General Monte Carlo Optical Simulator for Biomedical Optics
A high-performance public-domain Monte Carlo optical simulator is highly desirable to solve complex heterogeneous optical problems in biomedical engineering. Recently, we developed a Tetrahedron-based Inhomogeneous Monte- ...
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.
How to Define the Next Generation Cardiac CT Architecture? - a Contemporary Challenge for Interdisciplinary Collaboration
Cardiovascular diseases are pervasive with high mortality and morbidity at tremendous social and healthcare costs. There are urgent needs for significantly higher fidelity cardiac CT with substantially lower radiation dose, ...
