High-resolution imaging in a deep turbid medium based on an ultrasound-switchable fluorescence technique
(American Institute of Physics (AIP)Department of Bioengineering, The University of Texas at Arlington, 2012)**Please note that the full text is embargoed** ABSTRACT: The spatial resolution of fluorescence imaging techniques in deep optically turbid media such as tissues is limited by photon diffusion. To break the diffusion ... -
IMPACT OF MUSCULAR FATIGUE AND ITS MODULATION USING TRANSCRANIAL PHOTOBIOMODULATION (tPBM) ON THE HUMAN BRAIN MEASURED BY FUNCTIONAL NEAR-INFRARED SPECTROSCOPY (fNIRS)
(2020-07-22)When performing exercise, the brain must register and simultaneously integrate input from feedforward (i.e., central command) and feedback (e.g., exercise pressor reflex) neural mechanisms to make appropriate cardiovascular ... -
Implantable Drug Delivery System With In-plane Micropump
(Biomedical Engineering, 2007-08-23)A MEMS based Implantable Drug Delivery System (IDDS) is discussed. The heart of the system is an in-plane MEMS micropump enables us to make a compact, inexpensive system. A conceptual IDDS design is proposed. This design ... -
Implementation of a pain generator controlled by pressure and feasability in its applications for functional near-infrared spectroscopy
(Biomedical Engineering, 2011-10-11)Pain is a sensory and emotional experience as a result of possible or definite tissue damage. The level of pain is subjective to the individual's consciousness of sensory stimuli. Pain stimuli can be noxious (i.e., ... -
Improving optical contact for functional near-infrared brain spectroscopy and imaging with brush optodes
(OSA PublisherDepartment of Bioengineering, The University of Texas at Arlington, 2012-05-01)A novel brush optode was designed and demonstrated to overcome poor optical contact with the scalp that can occur during functional near infrared spectroscopy (fNIRS) and imaging due to light obstruction by hair. The ... -
