This section lists the more common questions our customers have about the moorLDI2™ system. If you have a question you would like answered that does not appear below then please email us. We are happy to help!
Q. Why are there a number of variants in the moorLDI2™ family?
A. Although moorLDI2-IR™ is our most popular imaging system we recognise that there are many cases where a standard 'one size fits all' solution does not fit as well as a tailored solution! That is why we offer a range to allow ultra high resolution imaging (100 pixels/square mm), dual wavelength imaging (to compare flow from different vascular beds) and imagers that scan using visible lasers (for low power applications) alongside the standard moorLDI2-IR™. If you are not sure which version to pick then we would be happy to advise.
Q. What is the largest area you can scan in one image?
A. All moorLDI2™ variants (apart from the High Resolution) will scan a 50x50cm area comfortably. For the highest resolution, choose moorLDI2-HR™ - this will scan 2.5cm x 2.5cm with 256 x 256 pixels - around 100 pixels for each square mm!
Q. How often should the moorLDI2™ be calibrated?
A. We supply a sealed calibration block to allow the user to easily check and calibrate their system if necessary. We recommend regular checking (weekly) but in practice re-calibration is rarely required.
Q. How can I assess responses to Iontophoresis or Skin Heating with moorLDI2™?
A. Set the imager to repeat scan mode so it is scanning the same area repeatedly (you can choose the number of scans and time between each). Clear heating chambers and iontophoresis chambers are available from Moor that allow the imager to 'see' the area that is being stimulated to allow you to compare changes in flow at the stimulated site relative to surrounding tissue.
Q. What are the advantages of a continuously scanning beam?
A. moorLDI2™ uses the patented continuous scanning technique. This means the laser beam does not stop during measurement resulting in a much faster scan. This fast mode is essential for large area clinical assessments. The movement pattern is smooth, deliberate and well defined. For low flow applications we recommend slowing the beam - easily done through scan configuration.
