1. Laser Doppler perfusion imaging : methodology and skin applications
Abstract : Over the last decade a number of emerging technologies have become available for the non-invasive study of skin anatomy and physiology. In this thesis, a method for mapping tissue perfusion based on the laser Doppler technique is presented together with some of the associated experimental and clinical applications. READ MORE

2. Characterisation and treatment of patients with port wine stains with special reference to the emotional impact
Abstract : This thesis covers 12 years of experience in treating patients with congenital capillary malformations, so called port wine stains (PWS). The wide variation in treatment response to laser therapy has developed a profound need for the development of objective devises to measure treatment outcome, so that the maximum effectiveness of therapy can be achieved without unnecessary treatments.

3. Laser Doppler imaging of patch tests : a methodological and comparative study with visual assessments
Abstract : Optimal test technique for most allergens is lacking. Despite technological progress in the 20th century, patch tests are habitually still assessed visually. Morphology of definite positive patch tests is unknown, reflected by various reading scales available and false-positive tests. READ MORE

4. Intrinsic and extrinsic protection of the brain
Abstract : The brain is a complex organ and critically dependent on its oxygen metabolism and blood supply. The purpose of the present study was twofold: firstly to design, evaluate, and adopt a physiologically stable experimental model for repeated measurements of cerebral cortical microvascular perfusion by a new laser Doppler technique (experimental part (I) - intrinsic model).

5. Blood Flow Dynamics in Burns
Abstract : Objectives:Burns of intermediate thickness are hard to evaluate clinically. This often leads to unnecessary delays of up to 14 days before a surgical decision can be made. To counter this, several objective methods have been developed to determine the healing potential of the wound. READ MORE
