The sliders (and the relevant arrow buttons) near
Detector Gain
,
Ampl. Offset
and
Ampl. Gain
enable you to set the photomultiplier of the selected channel during continuous scanning.
−
Detector Gain: Setting of the high voltage of the PMT photomultiplier - setting of image contrast
and brightness (values available between 80 and 1250)
−
Amplifier Offset: Setting of the electronic offset - background of the image can be set (values
available between -2 and 0.1)
−
Amplifier Gain: Amplification factor (values available between 1 and 3)
The
parameters
Detector Gain
,
Ampl. Offset
and
Ampl. Gain
are described in section
Pinhole / Detector Gain / Ampl. Offset / Ampl. Gain
(see page 4-349) in the context of
image optimization. In case the
Lambda
Mode
has been chosen in the
Configuration Control
window only the META channel
ChS
is displayed in the
Channel
settings of the
Scan
Control
window.
The parameters of a ratio channel are set in a
separate dialog box.
•
Click on the button of a ratio channel (e.g.
R1
).
The dialog box for the setting of the ratio
parameters is displayed.
Clicking on the required tabs enables you to
choose from four formulas (
Type 1
to
4
) for ratio
calculation. The relevant decimal values can be
entered in the input boxes via the keyboard. The
entered values remain unchanged even after
switchover to another formula and can be
reactivated any time.
The formula type activated last is always used for
ratio formation during the scan procedure. If the
input box does not contain any value at all or no
suitable value, the useful value last used will be
activated.
The ratio channels are displayed in the
Image
Display
window (see Fig. 4-60).
•
Select the required formula and enter the
relevant values.
Letters can be entered into the formula fields
which will be valued as 1; it is also possible to
make no entry, which will also be valued as 1, but
will not be displayed.
Set by min/max (in Scan Control window -
Channels
mode) allows the definition of the
display scaling according to the expected minimal
and maximal values.
