In this paper, a novel imaging technique for enhancing 3-D vision is proposed. The enhancement is achieved with the help of 3-D time-of-flight camera, this 3D camera delivers the intensity and depth information of the scene in real time. Although this kind of 3-D cameras provide accurate depth information, its low 2-D image resolution tends to be a(More)
AIMS In symptomatic patients with suspected coronary artery disease (CAD), computed tomographic angiography (CTA) improves patient selection for invasive coronary angiography (ICA) compared with functional testing. The impact of measuring fractional flow reserve by CTA (FFRCT) is unknown. METHODS AND RESULTS At 11 sites, 584 patients with new onset chest(More)
BACKGROUND Evaluating beneficial effects of potential protective therapies following cardiac arrest in rodent models could be enhanced by exploring behavior and cognitive functions. The Morris Water Maze is a well-known cognitive paradigm to test spatial learning and memory. RESULTS Behavioral testing with the Morris Water Maze in Sprague-Dawley rats (300(More)
Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post-resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during(More)
Time-of-flight (Tof) imaging based on the photonic mixer device (PMD) or similar ToF imaging solutions has been limited to short distances in the past, due to limited lighting devices and low sensitivity of ToF imaging chips. Long-range distance measurements are typically the domain of laser scanning systems. In this paper, PMD based medium- and long-range(More)
AIM OF THE STUDY To evaluate all brain regions reported to be selectively vulnerable to global ischaemia in a pig cardiac arrest model with different durations of no-flow by establishing a semi-quantitative brain histopathologic scoring system and to compare histological damage with neurological deficits. METHODS In a prospective randomised laboratory(More)
