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 ... -
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 ...
