INTRODUCTION: Laser Doppler imaging (LDI) is a relatively new method for assessing the functional aspect of superficial skin blood flow in systemic sclerosis (SSc) and Raynaud's phenomenon. There have been numerous technological developments to assist in managing burn wounds, including Laser Doppler Imaging (LDI), which is a helium-neon laser that objectively measures the blood flow and/or healing potential for indeterminate-depth burn wounds. Laser Doppler flowmetry (LDF), laser Doppler imaging (LDI) and laser speckle contrast imaging (LSCI) can non-invasively quantify digital perfusion and may be useful outcome measures for clinical trials in SSc-RP and/or SSc-DU. Laser Doppler perfusion imaging (LDI) is currently used in a variety of clinical applications, however, LDI instruments produce images of low resolution and have long scan times. A new optical perfusion imager using a laser speckle measurement technique and its use for in vivo blood flow measurements are described.

A diode is used to project an infrared light beam through the crown and pulp chamber of a tooth. The infrared light beam is scattered as it passes through the pulp tissue. The method most used to determine burn depth is clinical assessment, which is the least expensive, but not the most accurate.Laser Doppler imaging (LDI) is a technique with which a more accurate (>95%) estimate of burn depth can be made by measuring the dermal perfusion. Laser Doppler imaging (LDI) is often compared to laser speckle imaging and whilst there are some similarities, both techniques offer unique advantages. LDI generally offers deeper penetration enabling enhanced visualisation of small vessels below the tissue surface, perfect for angiogenesis modelling or through skull pre clinical cerebral blood flow imaging.

In this method, the changes in the frequency of the laser ligth provide information regarding perfusion of the monitored tissue. Laser Doppler imaging ( LDI) can be used to measure superficial blood flow in the skin and other vascularized tissues. A laser Doppler perfusion imager functions by projecting a visible-to- infrared laser beam onto the surface of a tissue.

In this review we shall discuss the relatively new technique of laser Doppler imaging (otherwise termed ‘scanning laser Doppler’), which gives a direct measure of microcirculatory flow. We believe laser Doppler imaging affords significant potential in the study of microcirculatory involvement of the rheumatic diseases and it is non-invasive. Laser Doppler The images of Laser Doppler like other Doppler based modalities, such as Doppler ultrasound, provide information about moving objects. A He-Ne laser is used for illumination of the skin and the backscattered and reflected light is collected by a detector.
