  2. 16. Level Set Segmentation and Volume Visualization of Vascular Trees

    Author : Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; level set methods; image segmentation; edge detection; visualization; volume rendering; blood vessels; angiography; vascular trees;

    Abstract : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. READ MORE

  4. 17. Volume kinetic development and application

    Author : Dan Drobin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Fluid therapy is a cornerstone in shock resuscitation in a such as treatment of anesthesia induce down regulation of the circulation and also restores many different types of dehydrated states. Current guidelines for fluid therapy are, however, based on experience, rules of thumb and effect-related end points, such as restoration of physiological parameters, which do not directly represent the volume effect of the fluid.

  5. 18. Endotracheal Suction a Reopened Problem

    Author : Birgitta Almgren; Marieann Högman; Mats Sjöquist; Anders Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Mechanical; ventilation; endotracheal; suction; lung; volume; loss; gas; exchange; Fysiologi; Physiology; Fysiologi;

    Abstract : During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. READ MORE

  6. 19. Efficient Methods for Direct Volume Rendering of Large Data Sets

    Author : Patric Ljung; Anders Ynnerman; Thomas Ertl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Scientific Visualization; Medical Imaging; Volume Rendering; Raycasting; Transfer Functions; Level-of-detail; Fuzzy Classification; Virtual Autopsies; Computer science; Datavetenskap;

    Abstract : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. READ MORE

  7. 20. Cohesive and Spectroscopic properties of the Lanthanides within the Hubbard I Approximation

    Author : Inka Laura Marie Locht; Igor Di Marco; Olle Eriksson; Annalisa Fasolino; Mikhail I. Katsnelson; Tim Wehling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lantanides; rare earths; cohesive properties; volume; bulk modulus; magnetism; magnetic properties; photoemission spectroscopy; XPS; BIS; Hubbard I Approximation; DMFT; DFT; RSPt; Full Potential Linear Muffin-tin orbitals; 4f electrons; localization; bonding; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : We describe the rare-earth elements using the Hubbard I approximation. We show that the theory reproduces the cohesive properties, like the volume and bulk modulus, and we find an excellent agreement between theory and experiment for the (inverse) photo emission spectra of the valence band.
