Background: Despite various exisiting monitoring methods, there is still a need for new technologies to improve the quality of post-operative evaluation of digital replantation. 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. 2019-04-08 Laser Doppler, speckle and related techniques for blood perfusion mapping and imaging R37 Figure 1. A typical laser speckle pattern.

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 laser Doppler perfusion imager functions by projecting a visible-to- infrared laser beam onto the surface of a tissue. Se hela listan på academic.oup.com 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. We present a full field laser Doppler imaging instrument that enables real-time in vivo assessment of blood flow in dermal tissue and skin. The instrument monitors the blood perfusion in an area of Laser Doppler (LDV) Systems TSI offers the Powersight-based, and individual solid-state laser-based Laser Doppler Velocimetry (LDV) systems. They can be be used for one, two, or three components of velocity measurements.
