1. 1. Image analysis tool for geometric variations of the jugular veins in ultrasonic sequences : Development and evaluation

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

   Författare :Arvid Westlund; [2018]
   Nyckelord :active contour; ultra sound; ultrasonic; image analysis; internal jugular veins; snake;

   Sammanfattning : The aim of this project is to develop and perform a first evaluation of a software, based on the active contour, which automatically computes the cross-section area of the internal jugular veins through a sequence of 90 ultrasound images. The software is intended to be useful in future research in the field of intra cranial pressure and its associated diseases. LÄS MER

3. 2. Modelling of Venous Biomechanics and Evaluation using Imaging, Positive Airway Pressure and Postural Changes

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Madelene Holmgren; [2016]
   Nyckelord :Jugular vein; Venous pressure; Positive airway pressure; Cross sectional area; Posture; Ultrasound; Halsven; Ventryck; Positivt luftvägstryck; Tvärsnittsarea; Kroppsposition; Ultraljud;

   Sammanfattning : Knowledge about biomechanical properties of veins is of importance for understanding the physiologyof the venous system. Specifically for this thesis there is a motivation based on an idea of how to usebiomechanics of the vein in the development of new non-invasive measurement techniques for assessingthe pressure in the brain.
