  1. 1. Calculation of scatter in cone beam CT : Steps towards a virtual tomograph

    Författare :Alexandr Malusek; Michael Sandborg; Gudrun Alm Carlsson; Michael Ljungberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Radiologi;

    Sammanfattning : Scattered photons—shortly scatter—are generated by interaction processes when photon beams interact with matter. In diagnostic radiology, they deteriorate image quality since they add an undesirable signal that lowers the contrast in projection radiography and causes cupping and streak artefacts in computed tomography (CT).

  2. 2. Att beskriva kronisk smärta : en lärprocess

    Författare :Michael Peolsson; Ullabeth Sätterlund Larsson; Roger Säljö; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kronisk smärta;

    Sammanfattning : Sammanfattningsvis syftar denna uppsats till att studera hur patienter beskriver sin smärta samt på vilka sätt de beskriver hur de utforskar sin smärta i vardagen. Jag vill med dessa beskrivningar som bakgrund lyfta fram patienters egen lärprocess om sin smärta. LÄS MER

  3. 3. Growth and integrity of the small intestine in malnutrition and trauma

    Författare :Michael Wirén; Linköpings universitet; []
    Nyckelord :Glutamine; growth factors; intestinal mucosa; malnutrition; permeability; surgery; MEDICINE; MEDICIN;

    Sammanfattning : The small intestine is an active metabolic organ constituting a functional and immunologic barrier to toxins and microbes in the intestinal lumen. Injuries are repaired by rapid cell replication, which depends on nutritional and humoral growth factors. Glutamine has been suggested to be the most important nutrient for the enterocytes. LÄS MER

  4. 4. Kalman Filters for Nonlinear Systems and Heavy-Tailed Noise

    Författare :Michael Roth; Fredrik Gustafsson; Simo Särkkä; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is on filtering in state space models. First, we examine approximate Kalman filters for nonlinear systems, where the optimal Bayesian filtering recursions cannot be solved exactly. These algorithms rely on the computation of certain expected values. LÄS MER

  5. 5. Propagation of change in an intelligent information system

    Författare :Michael Jansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis pursues the issue of propagation of change in an intelligent information system. Propagation of change occurs when a data base manager executes transactions repeatedly, though to different parts of a data base and possibly with some small variations. LÄS MER
