Optimized approach to decision fusion of heterogeneous data for breast cancer diagnosis.
(Med Phys, 2006-08)
As more diagnostic testing options become available to physicians, it becomes more difficult to combine various types of medical information together in order to optimize the overall diagnosis. To improve diagnostic performance, ...
Three-dimensional computer generated breast phantom based on empirical data
(MEDICAL IMAGING 2008: PHYSICS OF MEDICAL IMAGING, PTS 1-3, 2008)
An efficient finite element method for embedded interface problems
We focus on developing a computationally efficient finite element method for interface problems. Finite element methods are severely constrained in their ability to resolve interfaces. Many of these limitations stem ...
Coordinated analysis of delayed sprites with high-speed images and remote electromagnetic fields
One of the most dramatic discoveries in solar-terrestrial physics in the past two decades is the sprite, a high altitude optical glow produced by a lightning discharge. Previous sprite studies including both theoretical ...
Uncertainty propagation through software dependability models
Systems in critical applications employ various hardware and software fault-tolerance techniques to ensure high dependability. Stochastic models are often used to analyze the dependability of these systems and assess the ...
Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography.
The purpose of this work is to improve the NPS, and thus DQE, of CR images by correcting for pixel-to-pixel gain variations specific to each plate. Ten high-exposure open field images were taken with an RQA5 spectrum, with ...
Stream segregation on a single electrode as a function of pulse rate in cochlear implant listeners.
While cochlear implants usually provide a high level of speech recognition in quiet, speech recognition in noise and music appreciation remain challenging. In response to these issues, several studies have proposed increasing ...
Mechanical constraints enhance electrical energy densities of soft dielectrics
In this thesis, a new method---mechanical constraint to increase the energy density of soft dielectrics is described. Electromechanical breakdown is one of the main factors limiting the energy density and it is induced by ...
Comparative performance of multiview stereoscopic and mammographic display modalities for breast lesion detection.
PURPOSE: Mammography is known to be one of the most difficult radiographic exams to interpret. Mammography has important limitations, including the superposition of normal tissue that can obscure a mass, chance alignment ...
Attenuation of inflammatory events in human intervertebral disc cells with a tumor necrosis factor antagonist.
STUDY DESIGN: The inflammatory responses of primary human intervertebral disc (IVD) cells to tumor necrosis factor α (TNF-α) and an antagonist were evaluated in vitro. OBJECTIVE: To investigate an ability for soluble TNF ...
