Phase Aberration Correction for Real-Time 3D Transcranial Ultrasound Imaging
(2009)
Phase correction has the potential to increase the image quality of real-time 3D (RT3D)
ultrasound, especially for transcranial ultrasound. Such improvement would increase
the diagnostic utility of transcranial ultrasound, ...
Development of a Fourier Domain Low Coherence Interferometry Optical System for Applications in Early Cancer Detection
(2009)
Cancer is a disease that affects millions of people each year. While methods for
the prevention and treatment of the disease continue to advance, the early detection
of precancerous development remains a key factor in reducing ...
Distributional Fingerprinting of Cell Population Phenotypes and Drug Activities
(2015)
From gene expression to protein abundance, biological measurements have traditionally
been taken as population averages. Studies over the past decade, however, have established
the biological relevance of population ...
Bottom-up and Top-down Mechanisms of Visually-Guided Movements
(2016)
Interacting with the world is a two-step process of accurate sensing followed by coordinated
movement. Optimization of biologically-inspired robotic systems benefits from the
quantification and modeling of natural sensorimotor ...
Decoding Methods for Locomotor Brain-Machine Interfaces
(2015)
Cortical representations of rhythmic and discrete movements are analyzed and used
to create a novel neural decoding algorithm for brain-machine interfaces. This algorithm
is then implemented to decode both cyclic movements ...
A Model of Lung Tumor Angiogenesis in a Biomimetic Poly(ethylene glycol)-based Hydrogel System
(2016)
Tumor angiogenesis is critical to tumor growth and metastasis, yet much is unknown
about the role vascular cells play in the tumor microenvironment. A major outstanding
challenge associated with studying tumor angiogenesis ...
Design and Evaluation of a Transcutaneous Energy Transfer System
(2009)
A clinically viable brain-machine interface (BMI) requires a fully-implanted wireless
neural acquisition system to limit the impediments of percutaneous connections. For
an implanted system with an appreciable telemetry ...
The Role of Collagen VI in the Structure and Properties of the Knee Joint
(2009)
Knee pain is a common complaint among older Americans, nearly half of whom have developed
or will develop painful osteoarthritis. Osteoarthritis is primarily a disease of
articular cartilage, the low-friction, shock-absorbing ...
Non-Invasive Characterization of Cartilage Properties Using MR Imaging
(2015)
Osteoarthritis (OA) is a degenerative disease affecting articular cartilage, leading
to loss of its structure and function. Early stage OA is characterized by changes
in the extracellular matrix (ECM), including a reduction ...
Development of Swept Source Optical Coherence Tomography and Adaptive Optics Scanning Laser Ophthalmoscopy: Improved Imaging Speed and Handheld Applications
(2016)
Optical coherence tomography (OCT) is a noninvasive three-dimensional interferometric
imaging technique capable of achieving micrometer scale resolution. It is now a standard
of care in ophthalmology, where it is used to ...
