  2. 6. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies

    Author : Johan Antonsson; Karin Wårdell; Lars-Erik Augustinsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; Diffuse reflectance spectroscopy; Functional and stereotactic neurosurgery; Medical engineering; Medicinsk teknik;

    Abstract : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. READ MORE

  4. 7. Modeling and Simulation of Microdialysis in the Deep Brain Structures

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

    Abstract : 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. READ MORE

  5. 8. Characterisation and modelling of radio-frequency lesioning in functional neurosurgery

    Author : Ola Eriksson; Karin Wårdell; John Koivukangas; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : This thesis focuses on the characterisation and modelling of the radio frequency (RF) lesioning with emphasis on size estimation in functional neurosurgery. A computer-assisted video system has been set up for standardised test and documentation of protein clots generated by RF-lesioning electrodes in an albumin solution. READ MORE

  6. 9. Towards a broader use of phototesting : in research, clinical practice and skin cancer prevention

    Author : Magnus Falk; Chris Anderson; Karin Wårdell; Olle Lärkö; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phototesting; divergent beam; skin cancer prevention; self-reading; minimal erythema dose; sun protection behaviour; Dermatology and venerology; Dermatologi och venerologi;

    Abstract : In western societies, skin cancer incidence has increased dramatically over recent decades, due predominantly to increased sun exposure habits. Ultraviolet (UV) light exposure and individual light sensitivity of the skin constitute two important factors affecting the risk for skin cancer development. READ MORE

  7. 10. Evaluation of a Laser Doppler System for Myocardial Perfusion Monitoring

    Author : Carina Fors; Karin Wårdell; Henrik Casimir Ahn; Maria Lindén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; myocardial microcirculation; coronary artery bypass graft; Medical engineering; Medicinsk teknik;

    Abstract : Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method - based on laser Doppler flowmetry (LDF) - for detection of intra- and postoperative ischemia by myocardial perfusion monitoring is evaluated. READ MORE
