Research interests
General Interests: General and comparative aspects of thermal physiology in man and animals, including birds with main emphasis on cold temperature physiology. Cardiovascular disease, cold climate and winter mortality. Natural age related and pathophysiological aspects of peripheral circulation, medical Thermography in clinical and experimental research (main focus at present).
Key words: Integrative physiology, thermal physiology, regulation of body temperature, cold tolerance, shivering, peripheral circulation, thermal responsiveness, epidemiology of cardiovascular disease and its connection to climate, indoor climate & housing, cold exposure, peripheral vascular disease, medical thermography
Medical Thermography
Since the start of 2001 I have been leading a small research group in the field of Medical Thermography (infrared thermal imaging). At the Department of Radiology, University Hospital North Norway (UNN), we have a dedicated medicalthermography. We have collaborative projects with several different departments at UNN. This laboratory is the first of its kind in Norway. The Department of Radiology UNN has financed the expertise we needed to couple the infrared camera software system to the hospitals image and retrival (IMPAX) system. The system also allows medical personnel the possibility of ordering a thermographic examination for patients electronically, just as they can order an x-ray, CT, MRI etc. Processed images are then stored on the IMPAX system. Our laboratory at UNN is the most sophisticated of its kind in Scandinavia for thermographic examinations.
