    Författare :Torbjörn M. J. Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Light scattering properties of inhomogeneous materials were investigated in this thesis. Optical properties of pigmented polyethylene foils were optimized to take advantage of radiative cooling and for water condensation. LÄS MER

  7. 10. Power Doppler - Principles and Potential Clinical Applications

    Författare :Anders Nilsson; PG Lindgren; Torbjörn Andersson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Ultrasonography; Doppler studies; Power Doppler; Volume flow; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Sammanfattning : The purpose of this work was to: a) Determine whether the amount of colour in a power Doppler image is dependent on the angle between the examined vessel and the soundbeam and/or on the velocity of the flow within the vessel; b) Investigate if a dependency on flow velocity could be used for the detection of volume flow differences and c) Define clinical applications utilising the improved sensitivity to low flow of PD.In the experimental studies (study I and II) a silicon tube in a water bath was insonated, the insonation angle and the volume flow changed and the resulting images stored, transferred to a personal computer and analysed with regard to the amount of colour present in the image.
