Laser-Doppler flowmetry (LDF) is a non-invasive technique for measuring the tissue blood flow. It has been shown in the skin that LDF discloses blood flow fluctuations due to vasomotor nerve activity. LDF can give measurements of blood flow at various sites of different tissue.

Laser doppler flowmetry in the hyperbaric environment
Lasers in Medical Science, 1997Continuous monitoring of laser Doppler (LD) flowmetry was performed in eight healthy volunteers (mean age 42.0 + 12.1 yr; range 25-62 yr) before, during and after hyperbaric oxygenation ([HBO at 2.5 and 1.95 ATA (atmosphere absolute)]).Two models of the discrimination analysis are presented which allow classification, resulting from the parameter ...

Waveform analysis applied to laser doppler flowmetry
Microsurgery, 1986AbstractLaser Doppler flowmetry (LDF) has been found useful in monitoring free flaps. In the present study, waveform analysis has been applied to the LDF waveform. Waveform changes were investigated in the microcirculation during varying degrees of arterial or venous occlusion in the saphenous island and flap of the dog and the human digit.

Vaginal Laser Doppler Flowmetry Pre- and Posthysterectomy
Journal of Sex & Marital Therapy, 2004The objective of this study was to demonstrate the applicability of laser doppler flowmetry to pre- and posthysterectomy vaginal blood flow assessment. We used laser Doppler flowmetry to measure pre-and postoperational vaginal blood flow in 8 premenopausal women undergoing benign hysterectomies; we also measured serum E2, FSH, FT and administered a ...

Laser Doppler Flowmetry for monitoring traumatized teeth
Dental Traumatology, 2001Abstract – Laser Doppler Flowmetry (LDF) has been shown to be valuable in monitoring revascularization of immature incisors following severe dental trauma. Several investigators have demonstrated the ability of LDF to record blood flow signals from vital tooth pulps.

Application of Laser Doppler Flowmetry in Neurosurgery
Neurosurgery Clinics of North America, 1996Experience with LDF has indicated that intraoperative estimation of cerebral blood flow can be very useful and that long-term recordings of cortical perfusion pressure are possible. The disadvantage of LDF is that measurements are extremely local and that the units of measurements are arbitrary.

Principles of Laser-Doppler Flowmetry
1990Light scattering has long been used to probe properties of bulk matter. In transparent media such as air or clear water, measurements can be analyzed easily and remote sensing can be done over great distances. The basic principles relating the intensity of scattered light to underlying molecular structure were established by Lord Rayleigh in his ...

Laser Doppler Flowmetry in Animals
2012This chapter will describe the technique known as laser Doppler fl owmetry and its use in animals. Because the technique is based on light, it permits noninvasive measurements of perfusion in a tissue that can be illuminated, but perhaps its greatest strength is that it provides a continuous measurement.

A critical review of laser Doppler flowmetry
Journal of Medical Engineering & Technology, 1990Laser Doppler flowmetry (LDF) is now a well-established, non-invasive technique for measuring microvascular blood perfusion. However, there are a number of factors which can seriously affect the interpretation of the laser Doppler signal which are often not considered during routine use.

Laser Doppler flowmetrie on small animal
Acta Ophthalmologica, 2014AbstractWe present a compact fundus camera designed to measure the blood flow in small animals based on laser Doppler flowmetry (LDF). The small animal is immobilized on a modified stereotaxic table and the pupil of the LDF device is superposed by translation to the pupil’s eye of the animal.
