Laser Doppler Perfusion Monitoring and Imaging especially

Multimodal guidning vid neurokirurgi - Stiftelsen för strategisk

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.

2D Laser Doppler images provide a sub-surface map of perfusion of the skin as a metabolic indicator of angiogenesis underlying malignancies or other diseases processes. Laser Doppler imaging (scanning laser Doppler) LDF offers continuous perfusion measurement. However, cutaneous circulation is known to be heterogeneous, and examining a small area of perfusion does not necessarily give representative data for the surrounding perfusion [ 16 ]. Laser Doppler flowmetry (LDF) measures cerebral blood flow (CBF) at a single point on the cortical surface using a confocal laser and detector pair.

The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells.

A laser Doppler perfusion imager functions by projecting a visible-to- infrared laser beam onto the surface of a tissue. 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. 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.

Gerlacha, V We report on narrowband laser Doppler imaging of superficial pulsatile motion of the thumb by heterodyne holographic interferometry with a camera refreshed at 60 Hz. A transient blood flow interruption experiment in a healthy volunteer is performed and compared to blood pulse monitoring. Laser speckle perfusion imaging, for In-vivo imaging, real time Intrinsic signal & blood flow monitoring, for clinical applications such as MCAO model, CBF,HIL., etc. 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.

The cutaneous vascular axon reflex characterized by laser Doppler perfusion imaging. Submitted to Journal of Physiology 1992 Another observation from this study is the enormous potential of the new technique of laser Doppler imaging (scanning laser Doppler) to quantify treatment responsiveness objectively in patients with Raynaud's phenomenon.
