  1. 11. Evaluation of 3D MRI Image Registration Methods

    University essay from Linköpings universitet/Datorseende

    Author : Magnus Ivarsson; [2017]
    Keywords : ;

    Abstract : Image registration is the process of geometrically deforming a template image into a reference image. This technique is important and widely used within thefield of medical IT. The purpose could be to detect image variations, pathologicaldevelopment or in the company AMRA’s case, to quantify fat tissue in variousparts of the human body. READ MORE

  3. 12. Implementation and evaluation of functional connectivity measures -­ a resting state fMRI study of cognitively impaired subjects

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Hampus Ohlsson; [2014]
    Keywords : Medicine and Health Sciences;

    Abstract : Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is often used to map brain networks or Resting State Networks (RSNs). The networks are estimated by calculating how similarly certain spatially distinct brain regions behave. These networks have been shown to dier in individuals with many dierent kinds of cognitive diseases. READ MORE

  4. 13. Evaluation of weighting functions for Sidelobe control in UWB SAR image processing

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Habiba Akhter; [2013]
    Keywords : Image processing; Synthetic aperture radar SAR ; Ultra Wideband UWB ; Apodization; Impulse Response IPR Function;

    Abstract : Ultra wideband (UWB) Synthetic Aperture Radar (SAR) holds huge possibilities for both terrestrial and celestial object sensing with excellent details which assists in science and technology. SAR systems associated with large antenna beamwidth, large signal bandwidth and low frequency operating in the VHF/UHF region is becoming gradually more popular because of their rising number of application in the areas of ground-penetrating radar (GPR) and foliage penetration radar (FOPEN).

  5. 14. The potential of support vector machine classification of land use and land cover using seasonality from MODIS satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Florian Sallaba; [2011]
    Keywords : geography; geomatics; remote sensing; MODIS; support vector machine; phenology; TIMESAT; geografi; geomatik; fjärranalys; fenologi; Earth and Environmental Sciences;

    Abstract : With respect to climate change it is necessary to study land use and land cover (LULC) and their changes. LULC are related directly and indirectly to climatic changes such as rising temperatures that trigger earlier onset of vegetation growing seasons (IPCC 2007). READ MORE

  6. 15. Human Whole Body Pharmacokinetic Minimal Model for the Liver Specific Contrast Agent Gd-EOB-DTPA

    University essay from Medicinsk radiofysik; Hälsouniversitetet

    Author : Mikael Fredrik Forsgren; [2011]
    Keywords : Gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid; Dynamic Contrast-Enhanced MRI; Pharmacokinetics; Liver; Ordinary Differential Equation; Mathematical Modeling; Systems Biology;

    Abstract : Magnetic resonance imaging (MRI) of the liver is an important non-invasive tool for diagnosing liver disease. A key application is dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). With the use of the hepatocyte specific contrast agent (CA) Gd-EOB-DTPA it is now possible to evaluate the liver function. READ MORE
