Full-field, video frame rate blood flow imaging

    moorFLPI Speckle Contrast Imager With Optional MS3 Mobile Stand

    This system has now been superseded by the moorFLPI-2, for full details please click here.

    The moorFLPI full field blood perfusion imaging system provides video frame rate images of blood flow in the microvasculature - up to 25 images per second.

    An optical zoom function enables resolutions exceeding 1M pixels per cm2. The resulting image is mainly of blood flow in the microvessels in the surface layers of the tissue being sampled for example the nutritional flow in skin. In exposed tissue where blood vessels are close to the surface e.g. open surgery, these will also be imaged. Compared to standard laser Doppler imaging the effective sampling depth is small.

    Ideally suited to any application where very dynamic changes are occurring - over a few seconds for example - when conventional laser Doppler imaging could not provide data with sufficient time resolution. It is possible to view pulsation in finger tips (see example below) and variations due to deep breath, occlusion/ ischaemia, reactive hyperaemia etc.

    The 60 second example, above, recorded at 5 images per second (maximum 25 images per second) shows reduction in flow due to local occlusion with a pressure cuff and subsequent increase in flow when the cuff is deflated.

    The above example shows a 3 day old chick embryo within the egg shell. A small section (about 1.5cm diameter) of the egg shell has been cut away so that the heart and surrounding vessels can be imaged. The example has been recorded at 25 frames per second using the standard spatial mode. Click here to download the above example of the pulsating heart and surrounding vessels.

    A full range of accessories are available for clinical and research environments.

    As with all our products quality and reliability is assured with our standard two year manufacturers warranty.
