ULTRASOUND SWITCHABLE FLUORESCENCE IMAGING BASED ON A TIME GATED ICCD CAMERA
(2019-08-08)Ultrasound switchable fluorescence (USF) imaging has been proposed as a novel imaging modality which provides microscopic fluorescence imaging in centimeter-deep tissue. USF is possible to reveal many interesting phenomena ... -
Ultrasound-modulated Fluorescence Techniques
(Biomedical Engineering, 2014-09-17)Ultrasound-modulated fluorescence (UMF) imaging has been proposed as a novel imaging modality by combining ultrasound and optical imaging techniques for early cancer detection. In UMF, a focused ultrasound beam is used to ... -
UNDERSTANDING KEY GENETIC MUTATIONS AND MOLECULAR ALTERATIONS ON INCREASING MIGRATION, VIABILITY, DRUG RESISTANCE OF MALIGNANT BRAIN TUMOR IN CONFINEMENT
(2017-08-10)There are more than 120 types of primary brain and central nervous system tumors that affect people of all ages. Glioblastoma multiforme (GBM), for example, is the most frequent type of brain cancers and also among the ... -
UNDERSTANDING SCALP EEG IN RESPONSE TO NEWSVENDOR DECISION-MAKING AND FEEDBACK
(2019-05-22)Neuroeconomics is an emerging field integrating economic theories with neuroscience to enhance the understanding on how humans make decisions under different cost-effective conditions. Understanding the brain network ... -
Unravelling the Mysteries of Cognitive Decline in Cancer Survivors Using Functional Near Infrared Spectroscopy
(2017-06-14)In recent years, there has been an increased incidence of cognitive impairment in cancer survivors as a side-effect of chemotherapy. This troubling deterioration in cognitive ability is commonly termed as 'Chemo brain' in ... -
Use Of Near Infrared And Visible Spectroscopies To Determine Optical Properties Of Rat Nervous System
(Biomedical Engineering, 2007-08-23)Changes to the anatomical or physiological structure of the neuronal circuitry are known to produce a change in the optical properties of the tissue under investigation. The goal of this thesis is to determine changes in ... -
Vascular Stent Analysis
(Biomedical Engineering, 2007-08-23)It is important for cardiologist to understand the stresses and strains the stent experiences during deployment. We created a 3-D model of the coiled stent which is exported into ANSYS creating the finite element model. ... -
A Viscoelastic Model For Human Prolapsed Vaginal Wall Tissue
(Biomedical Engineering, 2012-04-11)Pelvic organ prolapse (POP) affects thousands of elderly women each year. Improvements in surgical repair could benefit from the understanding of the biomechanical properties of the vaginal wall (VW) tissues to better ... -
Visible To Near Infra Red Hyperspectral Imaging: Visualizing The Neurological And Biological Nature Of Ischemic Tissue
(Biomedical Engineering, 2009-09-16)Diabetic Neuropathy is a neuropathic disorder which is associated with Diabetes Mellitus. It is known to result in lower limb ulcers which can lead to amputation. Nerve damage, microvascular dysfunctions and use of ill ... -
Visible Versus Near-infrared Light Penetration Depth Analysis In An Intralipid Suspension As It Relates To Clinical Hyperspectral Images
(Biomedical Engineering, 2008-09-17)We determine the penetration depth of near-infrared and visible light in a tissue phantom model using various image processing techniques and chemometrics and use these results to demonstrate the application of a multimodal ... -
Wavelet coherence analysis of dynamic cerebral autoregulation in neonatal hypoxic–ischemic encephalopathy
(ElsevierDepartment of Bioengineering, The University of Texas at Arlington, 2016-01-25)Cerebral autoregulation represents the physiological mechanisms that keep brain perfusion relatively constant in the face of changes in blood pressure and thus plays an essential role in normal brain function. This study ... -
Whole-head functional brain imaging of economic risk decision making and transcranial photobiomodulation with fNIRS and EEG
(2020-09-08)Functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) are two non-invasive brain imaging or mapping modalities that allow us to measure cerebral hemodynamic and electrophysiological changes in the ... -
Wide Field Of View Imaging Of Premotor And Sensorimotor Cortex activation patterns by functional near infrared spectroscopy
(Biomedical Engineering, 2011-03-03)Functional near infrared spectroscopy (fNIRS) is a non-invasive optical technique which can measure concentration changes of oxygenated (HbO), deoxygenated (HbR), and total hemoglobin (HbT) in brain tissue that are induced ... -
Wireless Closed-loop Feedback Systems For Automatic Detection And Suppression Of Nociceptive Signals
(Biomedical Engineering, 2011-10-11)Chronic pain is an important public health issue. Several approaches have been implemented for management of chronic pain, including surgical implantation of neurostimulators. Neurostimulators have been used in clinics for ...
