  1. 1. On modelling and simulation of perfused tissue during thermal treatment : thermal analysis of blood perfusion and lesioning during ablative neurosurgery

    Författare :Joakim Wren; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Thermal treatment means therapy for which heat is the therapeutic agent. During treatment, the tissue temperature is increased to an injurious temperature (higher than 43 °C for the most widely used treatments). The aim is to reach necrotic temperature in the treatment area and non-lethal temperature outside the same. LÄS MER

  2. 2. Modeling and Simulation of Microdialysis in the Deep Brain Structures

    Författare :Elin Diczfalusy; Karin Wårdell; Mats Andersson; Joakim Wren; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Sammanfattning : Microdialysis is a method for monitoring of the local biochemical environment in a region of interest. The method uses a catheter, mimicking the function of a blood capillary, to sample substances from the surrounding medium through diffusion. LÄS MER
