Pinhole and Collimator Adjustment
Adjustment of the LSM 510 pinholes can be performed manually or automatically.
If several channels are used to produce the image, all the used pinholes must be adjusted separately.
(1)
Manual pinhole and collimator adjustment
The position of the pinhole relative to the detector in terms of X-Y-Z coordinates contributes substantially
to image optimization.
Requirements to make pinhole position changes visible immediately:
−
The image must be scanned by the continuous scan method.
−
Select a fast scanning speed.
−
Measurement with Average Number 1 only (no averaging of several measurements).
−
On the
Channel Settings
panel (click on
Channels
button in the
Scan Control
window), select
the pinhole diameter so as to have the best possible image contrast.
•
Click on the
Pinhole
button in the
Maintain
subordinate toolbar.
•
Select the pinhole to be adjusted from the
Description
list box.
•
Use the
Diameter
slider to set the smallest
possible size which produces a good, high-
contrast image.
−
This setting changes the pinhole diameter.
−
The
Z Slice
display box simultaneously
displays the depth resolution corresponding
to the pinhole diameter.
Image optimization can be effected with
the
Range Indicator
or in the
Line-Scan
mode.
•
Optimize the pinhole position in X, Y and Z (Z
only for PH1) relative to the PMT using the X, Y
and Z sliders to maximum image brightness.
•
Click on the
Save Current Position
button to
save the pinhole adjustment.
•
Removing the
Current Positions
slider in the
Collimator
panel allows the collimator to be adjusted to maximum image brightness. Optimum
collimator adjustment obtained in this way can be stored by clicking on the
Save Current Position
button.
•
Click on the
Stop
button to stop the continuous scan.
Please do not make any program manipulations while the automatic pinhole adjustment is
running (status display is red - busy).
