BACKGROUND One of the key clinical features of Alzheimer's disease (AD) is impairment in daily functioning. Patients with mild cognitive impairment (MCI) also commonly have mild problems performing complex tasks. Information and communication technology (ICT), particularly techniques involving imaging and video processing, is of interest in order to improve(More)

GridPix detector prototypes have been made using a TimePix pixel chip and a PSI 46 pixel chip. A system of discharge protection has been successfully tested. GridPix detectors have been tested using cosmic rays, a 90Sr source and the T9 test beam facility at CERN. GridPix detectors perform well for 3D track reconstruction, dE/dx measurements and transition(More)
—In this paper, we present a method for the automated detection of lumen and media–adventitia border in intravascular ultrasound (IVUS) images. The method is based on non-parametric deformable models for accurate IVUS image segmentation.The proposed method is evaluated using 50 IVUS frames from 10 patients. The obtained results demonstrate that our method(More)
