7.9 FLUOROSCOPY MODES
7.9.1 CONTINUOUS AND PULSE FLUOROSCOPY
Both fluoroscopy modes work with automatic exposure rate control (AERC), unless manual
exposure rate setting has been selected explicitly by the user.
The tube voltage and the tube current are adjusted automatically, taking into account the selected
fluoroscopy program as well as the thickness and structure of the object.
Automatic exposure rate control (AERC) is active on all three Fluoroscopic modes, and reduces
the radiation burden of both patient and operating staff to a minimum and prevents overexposure
of the screened body region.
