To view a scan region on the tissue:
- click Mark in LD Photo / Mark Beam or press the M key, to start continuous
marking.
- click Abort or press the A key to end the continuous marking..
Clicking on the LD Photo button will start a fast (32 lines) photo image.
Clicking on the Clear button will clear the photo image.
Scan area setup preferences can be saved using the Save Setup File button at the bottom of the
screen. To load a previously saved setup file click on the Load Setup File button.
Factory Setup is the setup at manufacture (the user can set his/her own default settings).
Factory Setup is Scan Size Normal, XO=YO=0, dX=dY=256, Scan Resolution X=Y= 256, Scan
Speed=4ms/pixel
HINTS
1. It is easier to target a scan region on the tissue (where the moorLDI 2 scan head is capable of
movement) if the scan region is symmetrical about the centre of the scan window. In this
configuration the beam position defaults to the centre of the scan region.
2. A 'photo' image of the tissue can be scanned ( LD Photo in the LD Photo/Mark Beam box).
This can be used to check for saturation of the detected signals (DC too high indicated by
white regions of the grey scale image and to aid positioning of the scan region box. The
image is low resolution (32 lines) to reduce the scan time.
5. The Scan Speed can be increased by reducing the number of lines scanned, i.e. change Scan
Resolution (dY) in the Y direction. For example if dY is decreased from 256 to 128 the scan
time is halved.
3. The Estimated Time indicates approximately how long it will take to scan the selected area.
