7.
You will be prompted to either manually enter the scan head to tissue distance or confirm the
automatic distance measurement itself.
8. Click on the green flag start icon
(
Note you can pause or stop the scan at any
time).
8.
At the end of a measurement save the image by clicking on the save icon or select:
File
Save As
Follow the normal Windows
procedure for entering a filename.
Congratulations! You have captured your first laser Doppler image.
5.3 CHANGING SCAN PARAMETERS
Many configurations of the
moorLDI
2 are possible. The basic changes of
scan size
and
distance
require changes to the Image Scan configuration and System configuration.
The
duration
of a scan can be reduced by lowering the scan resolution.
Using the
Repeat Scan
function successive scans can be performed at preset or indefinite intervals,
as the situation requires.
Please spend some time exploring the
moorLDI
2 software to get to know its functions and to make
full use of its capabilities.
5.4 MOORLDI2-HR AND MOORLDI2-HIR SCAN DISTANCE AND SCAN SPEED
Scan areas at a given scan distance are approximately one half of those for the standard instruments.
Note:-
1.
To get the high resolution scan distances between 20cm to 30cm must be used
2.
That, because of the small (focussed) laser spot size, movement artefact noise generated as
the beam moves over the scan area is greater than from a standard moorLDI instrument.
For some measurements eg low flow regions, it may therefore be necessary to scan at a slow
speed 10m/s per pixel, or even slower at 50m/s per pixel, rather than the fast 4ms/pixel speed.
