Digital Spectral Separation Methods And Systems For Bioluminescence Imaging
(Optical Society of America, 2008-01-01)
We propose a digital spectral separation (DSS) system and methods to extract spectral information optimally from a weak multispectral signal such as in the bioluminescent imaging (BLI) studies. This system utilizes our ...
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- ...
Results in the Past
Past research results include the following: • Modern CT scanners that use spiral-beam scanning and perform >100-million scans annually in the USA • Construction of the only 500nm resolution micro-CT system on the East ...
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 ...
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 ...
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.
Gel'fand-Graev's Reconstruction Formula in the 3D Real Space - a Framework towards a General Interior Tomography Theory
In [1-4], I. M. Gel'fand and M. I. Graev proposed inversion formulas for x-ray transforms in different spaces. In particular, Gel’fand-Graev’s inversion formula  is a fundamental relationship linking projection data to ...
