Laser Doppler Imaging Scan De diepte van de brandwonde (eerste-, tweede- of derdegraads) bepaalt de genezingsperiode, de mate van littekenvorming en de noodzaak tot heelkunde. Omdat het moeilijk is om de precieze diepte van de brandwonde correct in te schatten, en omdat de wonde de eerste 48 uur nog evolueert, wordt er tussen de 48 en de 120 uur na de verbranding een LDI-scan uitgevoerd.

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.

Laser Doppler Velocimetry (LDV) is a technique which allows the measurement of velocity at a point in a flow field with a high temporal resolution. Whenever a micron-sized liquid or solid particle entrained in a fluid passes through the intersection of two laser beams, the scattered light received from the particles fluctuates in intensity.

The purpose of the study is using a laser Doppler imaging device (Easy-LDI) as an additional tool to assess perfusion. In this method, the changes in the frequency of the laser ligth provide information regarding Laser Doppler perfusion monitoring measures the total local microcirculatory blood perfusion including the perfusion in capillaries (nutritive flow), arterioles, venules and shunting vessels. The definition of perfusion is the concentration of red blood cells times their average velocity.
