Advanced laser Doppler technology for non-contacting area velocity flow measurement. LaserFlow The LaserFlow  Laser Radar provides fast, automated, non-contact measurement capability for large-volume applications of up to 50 meter radius. Using Doppler ultrasound the probes provide immediate evidence of success in vascular reconstructive procedures.

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. laser Doppler imaging and thermography before and after argon laser treatment.

A laser source with an attached optical system produces a single laser beam. It is directed in a scanning fashion of the tissue within the ROI (region of interest) by a moving mirror. Backscattered light is captured by the detector. Reflections from moving objects (such as erythrocytes) are subject to the Doppler shift. 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.

Patients were reviewed … 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.

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 signals derived from a measuring site had been automatically excluded during processing. In the present study the stepper motors were set to move two steps at a time, and the lower cut-off frequency 2002-11-01 Laser Doppler imaging can enable mapping of the local arterial resistivity index, and the possibility to perform unambiguous identification of retinal arteries and veins on the basis of their systole-diastole variations, and reveal ocular hemodynamics in human eyes. Laser Doppler is typically used in order to confirm that occlusion has taken place and ischaemia has occurred. Skin Perfusion Pressure (SPP) Skin Perfusion Pressure (SPP) is the pressure required for restoring microcirculatory blood flow following release of carefully controlled occlusion. 2018-02-01 Laser Doppler imaging.
