Detection of vesicoureteral reflux using electrical impedance tomography
(IEEE, 2018-12-14)Objective: The purpose of this study is to detect vesicoureteral reflux (VUR) non-invasively using electrical impedance tomography (EIT). VUR is characterized by the backflow of urine from the bladder to the kidneys. ... -
Nano-sensitive optical coherence tomography
(Royal Society of Chemistry, 2014)Depth resolved label-free detection of structural changes with nanoscale sensitivity is an outstanding problem in the biological and physical sciences and has significant applications in both the fundamental research and ... -
Spatial frequency domain correlation mapping optical coherence tomography for nanoscale structural characterization
(AIP Publishing, 2019-09-16)Most of the fundamental pathological processes in living tissues exhibit changes at the nanoscale. Noninvasive, label-free detection of structural changes in biological samples pose a significant challenge to both researchers ... -
Static lesion detection in symmetric scenes using dual-frequency electrical impedance tomography
(NUI Galway, 2019-01-18)Tissues have characteristic frequency dependent impendence to electrical current. This property is exploited by Electrical Impedance Tomography (EIT), an emerging biomedical imaging technique. In EIT, electrical conductivity ... -
Understanding the changes of cone reflectance in adaptive optics flood illumination retinal images over three years
(Optical Society of America, 2016)Although there is increasing interest in the investigation of cone reflectance variability, little is understood about its characteristics over long time scales. Cone detection and its automation is now becoming a fundamental ...
