A new device combining laser Doppler perfusion imaging and digital photography

We describe a new method for acquisition and analysis of skin perfusion images acquired by laser Doppler scanning and digital photographs of the area scanned. Photographs are obtained with a commercial digital still video camera. A commercial software package is used to handle the perfusion image file and the digital photo. We describe software developed to assess blood flow distribution in detail in relation to the visual appearance of the skin, palpatory findings and other clinical signs. Possible clinical applications of the method described by case reports are post-operative evaluation of vascularized grafts and monitoring of treatment of chronic skin ulcers.
