9. SINGLE POINT MEASUREMENT (SPM)
9.1 INTRODUCTION
The Single Point Measurement (SPM) function enables real time monitoring of laser Doppler flux
and conc at a point on the tissue surface.
9.2 POSITIONING OF BEAM FOR SPM
To measure at the point of interest it is first necessary either to move the tissue to the beam position
or to move the beam to the position required.
9.3 BEAM MOVEMENT
Enter the
Scanner Setup
by clicking on the icon or
Setup
then
Scanner Setup
followed by
Image scan
selection.
Use of this window for imaging is explained in Section 5.4.
To move the beam, position the cursor at a point in the scan window and click the
right hand
mouse
button. The beam will move to a position corresponding to the new screen position.
9.4 BEAM MOVEMENT RELATIVE TO PHOTO IMAGE
If it is more convenient to position the beam relative to a photo image of the tissue this can be done
by selecting
LD Photo
in the
LD Photo/Mark Beam
box. This will scan the beam over the tissue
area and display a low resolution Photo Image (16 lines).
To move the beam, position the cursor at a point in the Photo window and click the
right hand
mouse button. The beam will move to a position corresponding to the new screen position.
9.5 SINGLE POINT MEASUREMENT WINDOW
After positioning the beam at the required tissue site enter the Single Point Measurement window by:
