Trigger (Pulsed Fluoro)
In Pulsed Fluoro, the trigger is necessary to synchronize the Fluoro gate with the imaging system
(Figure 3.20). The trigger input is provided on the Fluoro board:
−
J3A, pin 6 on Fluoro board P/N 9822.00
−
J3, pin 3 on Fluoro board P/N 11030.000
−
And its selection is done through Epsilon PC Tools (Fluoro Configuration, see Section 4.6).
−
The activation voltage level depends on the V
TH
(Section 3.4.1.2).

Fluoro Footswitch & Interlocks
Refer to Section 3.2.1 to interface the Fluoro pedals and to Section 3.4.2 for Fluoro Interlocks.
3.7.4
External Control for Fluoro Dose Stabilization
The generator provides an analog input for external control of the Fluoro dose stabilization. This is
optional since the
Epsilon
generator has a built-in dose stabilization circuitry (Section 5.5).
To remotely control the Fluoro stabilization, the line at J3 pin B3 (0 to 12 V
DC
, Figure 3.20) can be
used; this stabilization method requires that the ABS source in the Fluoro setup be set to
Rmt AEC
(Remote AEC, Section 4.5).
