3.6 ABC operation
3.6.1 Introduction
Automatic Brightness Control(ABC) always makes a regular image on the monitor by controling
the fluoroscopic tube-voltage or fluoroscopic tube-current according to the X-ray absorption of
a subject.
REX-R/F quickly copes with reaction speed of the monitor brightness according to the change of
a subject by controling simultaneously the fluoroscopic tube-voltage and fluoroscopic
tube-current.
3.6.2 Operating Sequences
5.
Start fluoroscopy by pressing the FLU button at tower part.
6.
Fluoroscopic tube-voltage and fluoroscopic tube-
current
irradiated to a patient during the fluoroscopy are displayed on
the LCD screen to make controller know it.
7.
ABC is geared with the range of 40
120KV for fluoroscopic
tube-voltage and of 0.4
4mA(Higher mA : Option) for
fluoroscopic tube-current according to the X-
ray absorption of
a subject during the fluoroscopy.
8.
To prevent the radiation from exposing e
xcessively, the time
for fluoroscopy isn't over 5 minutes and you can hear the
warning signal when the set period passes.
1.
Turning on the power by pressing the button for the x-
ray
sysytem.
2.Slecting tube 2(fluoroscpic mode).
3.Don't select the BUCKY because it
is fixed to the Tower
part.
4.
Slecting ABC at workstation.
