Head trauma and concussion in football players have recently received considerable media attention. Postmortem evidence suggests that accrual of damage to the brain may occur with repeated blows to the head, even when the individual blows fail to produce clinical symptoms. There is an urgent need for improved detection and characterization of head trauma to(More)
Concussion is a growing public health issue in the United States, and chronic traumatic encephalopathy (CTE) is the chief long-term concern linked to repeated concussions. Recently, attention has shifted toward subconcussive blows and the role they may play in the development of CTE. We recruited a cohort of high school football players for two seasons of(More)
—Optical character recognition (OCR) is an open problem and continues to be a challenging problem in academia. In this paper, we proposed and implemented a text detection framework which could be run on mobile platforms. We evaluated two methods-Segmentation by dilation and Smart Segmentation-that would effectively isolate text at different distances. We(More)
PURPOSE To develop a novel multiresolution MRI methodology for accurate estimation of glomerular filtration rate (GFR) in vivo. MATERIALS AND METHODS A three-dimensional golden-angle radial stack-of-stars (SoS) trajectory was used for data acquisition on a 3 Tesla MRI scanner. Multiresolution reconstruction and analysis was performed using arterial input(More)
Bio BIO Interests include medical imaging generally, and magnetic resonance imaging (MRI) in particular. Current efforts are focused on medical applications of MRI where real-time interactive imaging is important. Two examples are cardiac imaging, and the interactive guidance of interventional procedures. Specific interests include rapid methods for the(More)
Basic Description In this project we plan to develop an application on droid mobile phone which can highlight any input word in the picture of a text document given in the view finder. The user will enter a search parameter, ideally a word, and use the camera of the phone to scan the desired printed document for the search parameter. This application is(More)
PURPOSE To introduce a respiratory-gated high-spatiotemporal-resolution dynamic-contrast-enhanced MRI technique and a high-temporal-resolution aortic input function (HTR-AIF) estimation method for glomerular filtration rate (GFR) assessment in children. METHODS A high-spatiotemporal-resolution DCE-MRI method with view-shared reconstruction was modified to(More)
