Stream segregation on a single electrode as a function of pulse rate in cochlear implant listeners.
(J Acoust Soc Am, 2012-12)
While cochlear implants (CIs) usually provide high levels of speech recognition in quiet, speech recognition in noise remains challenging. To overcome these difficulties, it is important to understand how implanted listeners ...
Comparative performance of multiview stereoscopic and mammographic display modalities for breast lesion detection.
(Med Phys, 2011-04)
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 ...
The effects of osmotic stress on the structure and function of the cell nucleus.
(J Cell Biochem, 2010-02-15)
Osmotic stress is a potent regulator of the normal function of cells that are exposed to osmotically active environments under physiologic or pathologic conditions. The ability of cells to alter gene expression and metabolic ...
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)
Harmonic source wavefront aberration correction for ultrasound imaging.
(J Acoust Soc Am, 2011-01)
A method is proposed which uses a lower-frequency transmit to create a known harmonic acoustical source in tissue suitable for wavefront correction without a priori assumptions of the target or requiring a transponder. The ...
Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography.
(Med Phys, 2012-03)
PURPOSE: The purpose of this work is to improve the noise power spectrum (NPS), and thus the detective quantum efficiency (DQE), of computed radiography (CR) images by correcting for spatial gain variations specific to individual ...
Attenuation of inflammatory events in human intervertebral disc cells with a tumor necrosis factor antagonist.
(Spine (Phila Pa 1976), 2011-07-01)
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 ...
Knowledge-based IMRT treatment planning for prostate cancer.
(Med Phys, 2011-05)
PURPOSE: To demonstrate the feasibility of using a knowledge base of prior treatment plans to generate new prostate intensity modulated radiation therapy (IMRT) plans. Each new case would be matched against others in the ...
