Note 1 : This is valid for a tube with 14° anode angle. The HVL for a 22° anode is typically 0,5 mm
lower (@ 80 kV, 3 mm TF).
Note 2 : The C3 and higher numbered calibrations are only available for product versions 2.0 or
higher.
Note 3 : The C4 ( GECT (7°) ) is suitable for all GE CT tubes which have a 7° anode angle as well as
other manufacturers CT tubes and replacement tubes with a 7° anode angle. The C6 ( GECT
(10.5°) ) is suitable for GE CT tubes with a 10.5° anode angle..
