2. 6. Single fibre laser Doppler flowmetry for skeletal muscle perfusion measurements : methodological developments and clinical applications

   Author : Hongming Cai; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Measurements of microvascular blood flow in skeletal muscle by using the laser Doppler flowmetry (LDF) technique were first reported in 1979. The introduction of the single fibre technique in 1987 increased the possibilities of studying muscle perfusion under various physiological conditions without causing major tissue trauma. READ MORE

4. 7. 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

5. 8. Origin and processing of laser Doppler spectra

   Author : Mikael Arildsson; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Laser Doppler Flowmetry (LDF) is a technique for studying microvascular blood flow. Laser light is guided to the tissue and the backscattered light, after being Doppler shifted by moving Red Blood Cells (RBCs), is detected using a heterodyne process. READ MORE

6. 9. Rhinostereometry and laser doppler flowmetry : simultaneous measurements of inflammation and steroid effects in normal and allergic human nasal mucosa

   Author : Hans Grudemo; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Rhinastereometry; Laser Doppler Flowmetry; Nasal mucosa; Allergic rhinitis Histamine challenge;

   Abstract : This thesis describes the development of a combination of non-invasive methods for measuring different aspects of inflammation simultaneously in a selected part of the human nasal mucosa. It also describes use of this combination in studies of allergic nasal mucosa and the effects of intranasal steroids before and during the allergy season. READ MORE

7. 10. Optical Monitoring of Cerebral Microcirculation

   Author : Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

   Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).
