MoorLDLS2

The moorLDLS2™ line scanning system provides laser Doppler images of blood flow in the microvasculature with scan times as low as 4 seconds. The system employs a multi channel laser Doppler line to sweep across the tissue gathering data from 64 points simultaneously. The penetration properties of the laser line are comparable to the moorLDI2™ systems but the image acquisition times are much shorter.
The rapid scanning makes this system ideally suited for any application where the dynamic changes are too rapid to be captured by conventional laser Doppler imaging; where work volume is such that time/cost savings can be attained by using fast line scanning; and where it is necessary in a clinical/operative environment to minimise the scan time. 

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.



MoorFLPI

Speckle Contrast Imager

The moorFLPI full field blood perfusion imaging system provides video frame rate images of blood flow in themicrovasculature - 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 themicrovessels 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.

MoorFLPI-2

Speckle Contrast Imager

The NEW moorFLPI-2 blood flow imager uses the laser speckle contrast technique to deliver real-time, high-resolution blood flow images, providing outstanding performance in a wide range of pre-clinical and clinical research applications.

User-friendly features promote smooth workflow and enable the high through-put required to scan cohorts quickly and accurately. Advanced analysis functions help you to draw sound conclusions from your blood flow images.

moorFLPI-2 highlights include;

Image any exposed tissue (skin or surgically exposed tissues) and species.

Best spatial resolution of 10 microns per pixel.

Real-time video frames rates.

Image areas range from 5.6mm x 7.5mm to 15cm x 20cm.

Colour photo and blood flow images precisely matched, pixel for pixel.

Compact design with flexible stand options for clinic or laboratory.

Established pre-clinical and clinical research applications are wide-ranging; examples include;

Neuroscience – spreading cortical depression, stroke model.

Dermatology – inflammation and irritancy.

Oncology – experimental tumour growth, angiogenesis.

Pharmacology – local and systemic responses.

Plastic surgery – flap perfusion.

Chemical toxicology – inflammation and irritancy (e.g. response to intradermal capsaicin).

Intraoperative measurements – limb and visceral ischaemia and reperfusion.

Cardiovascular research – e.g. endothelial function with iontophoresis.

Please contact us, to discuss your specific application requirements with a Moor product specialist. Ask to see the new system in action, evaluate it at your own facility.





 

moorLDI2

Laser Doppler Imager

The moorLDI2™ imagers are able to map tissue blood flow over areas from 5cm x 5cm up to 50cm x 50cm with 256 x 256 pixel resolution; - each pixel being an actual measurement. At high scan rates, over 64,000 measurements are made in less than 5 minutes.

The imagers are suitable for a wide range of clinical and research investigations and measurement of blood flow in the microcirculation. The moorLDI2™ range features a CCD camera which produces a colour image of the scanned area, making the positioning and comparison of images easier. The moorLDI2-HR™ highest resolution version is available with resolution to 100 microns.

The moorLDI2™ laser Doppler blood perfusion imagers use a near infra-red laser beam (785nm in the standard moorLDI2-IR™ imager) or a visible red 633nm laser beam (moorLDI2-VR™ imager). In the moorLDI2-2λ™ dual wavelength system 633 and 830nm lasers are combined to allow simultaneous imaging with the two wavelengths.
