本节列出了对客户moorFLPI-2常见问题的解答。如果您的问题不在其中，请将问题电邮给我们。我们将乐于帮助！

Q. What is the penetration depth of moorFLPI-2?
A. The penetration depth will depend on the optical properties of the tissue sampled as in conventional laser Doppler imaging; however, the signal processed which results in the speckle contrast image is biased towards light coming from the more superficial layers of the tissue. The effective penetration depth will be less than a conventional laser Doppler imager so will focus far more on the nutritive layers and will be less influenced by flow from deeper and larger vessels.

Q. What is the largest area you can image with moorFLPI-2?
A. The image area is dependent on the optical zoom used and the distance from the scan head to the tissue. This allows full flexibility to study areas from 5.6mm x 7.5mm up to 225mm x 300mm (continuously variable with zoom lens).

Q. What is the spatial resolution of the moorFLPI-2?
A. The moorFLPI-2 offers up to 1M pixels per square cm (50um in spatial mode at up to 25Hz and 10um in temporal mode at up to 1Hz).

Q. How can I assess dynamic responses with moorFLPI-2?
A. The moorFLPI-2 is used in the same way as a conventional laser Doppler imager - changes from a baseline are commonly assessed. The only difference is in the image acquisition rate with moorFLPI-2 providing 25 images per second opening up many new and exciting research opportunities.

Q. Can I image blood vessels with moorFLPI-2?
A. Yes, if the blood vessels lie in the surface of the tissue being imaged and if the tissue covering the vessels is effectively transparent to the laser light. This makes the technique ideally suited to cerebral imaging and general open surgery

Q. How often do I need to calibrate the system?
A. The moorFLPI-2 is factory calibrated. The user can check zeroing and calibration as frequently as required; we recommend to check calibration monthly.

Q. Can I analyse the data from moorFLPI-2?
A. Images can be analysed in much the same way as a conventional laser Doppler images and sequences allowing comparisons of flow within the same image or in the same subject over time. The video capability also allows the user to define up to 16 regions of interest (that can be varied in size, shape and position) and plot flow in real time from those regions - akin to a 16 channel laser Doppler monitor. Frame grabbing allows the user to select images from the video at flexible or pre defined intervals to build a sequence for analysis.
