1. 21. On Aortic Blood Flow Simulations : Scale-Resolved Image-Based CFD

   Författare :Jonas Lantz; Matts Karlsson; Shawn Shadden; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis focuses on modeling and simulation of the blood flow in the aorta, the largest artery in the human body. It is an accepted fact that abnormal biological and mechanical interactions between the blood flow and the vessel wall are involved in the genesis and progression of cardiovascular diseases. LÄS MER

3. 22. Physical Aspects of Thermotherapy - A study of heat transport with a view to treatment optimisation

   Författare :Johan Olsrud; Sektion V; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance; non-invasive; temperature; coagulation; prostatic; menorrhagia; liver tumour; finite element method FEM ; thermal conductivity; intracavitary; interstitial; laser; Thermotherapy; hyperthermia; MRI; Medicine human and vertebrates ; Medicin människa och djur ; Physics; Fysik; Fysicumarkivet A:1998:Olsrud;

   Sammanfattning : Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. LÄS MER

4. 23. A Position Control-based Approach to Stiff Objects Haptic Rendering

   Författare :Yang Wang; Kjell Andersson; Lei Feng; Anders Robertsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; haptic rendering; position control-based approach; rigid-body interaction; Machine Design; Maskinkonstruktion;

   Sammanfattning : With electronic components and computational power becoming more portable and available to general consumers, applications like virtual reality (VR) and mixed reality (MR) are on the rise and renovating the industry of training simulators. Though it is not fully accepted in surgical robots, haptic force feedback can be safely introduced into various surgical training simulators to convey the necessary haptic cues needed to develop hand-eye coordination and motor skills.

5. 24. Modelling, Simulaltion, and Visualization of Deep Brain Stimulation

   Författare :Mattias Åström; Karin Wårdell; Göran Salerud; Stig Rehncrona; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Deep brain stimulation (DBS) is an effective surgical treatment for neurological diseases such as essential tremor, Parkinsonʹs disease (PD) and dystonia. DBS has so far been used in more than 70 000 patients with movement disorders, and is currently in trial for intractable Gilles de la Tourette’s syndrome, obsessive compulsive disorders, depression, and epilepsy.

7. 25. Patient-controlled sedation in procedural care

   Författare :Andreas Nilsson; Lena Nilsson; Folke Sjöberg; Eva Uustal; Lars I. Eriksson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The need for procedural sedation is extensive and on the increase in numbers of patients. Minor treatments or diagnostic procedures are being performed with inadequate sedation or even without any sedatives or analgesics. LÄS MER
