The lamp effect of laser Doppler flowmetry on teeth
Journal of Oral Rehabilitation, 2005summary The aim of this study is to analyse the intra and extracoronal scattering of laser light. Twelve vital teeth from 12 volunteer individuals (aged 22–29 years) were used. The camera removing the charge coupled device's infrared cut filter was used for imaging the laser Doppler flowmetry light during pulpal blood flow measurement.

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 ...

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 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.

The use of laser Doppler flowmetry in paediatric dentistry
European Archives of Paediatric Dentistry, 2011An early determination of pulpal vitality is crucial with respect to a correct differential diagnosis of revascularisation or necrosis and its treatment.Sensibility tests (cold, heat, electrical pulp test) in combination with radiographs are commonly promoted. However these tests are arbitrary, based on sensations and therefore not always reliable.

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.

Laser Doppler flowmetry in the diagnosis of chronic compartment syndrome [PDF]
The Journal of Bone and Joint Surgery. British volume, 1998 Chronic compartment syndrome (CCS) is usually considered to be due to ischaemia of muscle. We have attempted to use the direct measurement of muscle blood flow for diagnosis since the assessment of intracompartmental pressure does not provide accurate knowledge of the vascular state.

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.

Quantitative testing of sympathetic function with laser doppler flowmetry
Journal of Clinical Monitoring, 1992The objective of this study was to develop an indirect technique for evaluating dynamic changes in sympathetic function in humans.We used laser Doppler to monitor sympathetic mediated vasoconstrictive responses (VRs) produced by 3 different provocative stimuli: 4-second inspiratory gasp (IG), ice-water immersion (Ice), and a spring-loaded pin prick ...
