Measuring Automatic Exposure Control
Automatic Exposure Control (AEC) is a sequence that is automatically initiat-
ed when the footswitch pedal is released immediately after being pressed
down, in which the G-Arm system automatically calculates suitable loading
factors (kV, mA, and fluoroscopic duration) according to the physical charac-
teristics of the patient.
AEC applies to the following fluoroscopy mode:
●
Automatic Pulse Fluoroscopy
●
Automatic Continuous Fluoroscopy
●
Half Automatic Continuous Fluoroscopy
●
Half Automatic Pulse Fluoroscopy

Before starting to inspect monitor rotation movements, clear all the
obstacles within the movement range to make sure the viewing moni-
tors do not collide with any objects.
Rotate the viewing monitor assembly clockwise by pulling either
side of the viewing monitors. See if it can be moved smoothly and
reach its maximum rotation angle (180°).
Spin the monitor assembly backwards and stop the rotation move-
ment at a random position. Release the monitor. See if it can hold its
position and stay still.
Spin the monitor assembly counter-clockwise, passing its neutral
position, all the way to the other end position. See if the movement
is smooth and it can reach its maximum rotation angle (180°).
Take an exposure. Check whether the exposure lamp is illuminated
and the exposure sound beeps.
