WARNING
To protect the health of patients and staff against high radiation dosages, the
manual dose rate setting mode remains blocked until you have initiated radiation
in one of the fluoroscopy modes with automatic exposure rate control at least once.
Only use the manual exposure rate setting mode in exceptional circumstances.
The automatic exposure rate control provides optimum image quality whilst
minimizing the dose rate.
To generate an image in the manual exposure rate setting mode, do the
following:
• Select the desired organ program
• Select one of the fluoroscopy modes with automatic exposure rate
control:
•
Continuous Fluoroscopy
•
Pulsed Fluoroscopy
•
Snap Shot
• Initiate radiation for a brief moment.
• Press the Manual Exposure Rate Setting button on the mobile stand
and touch screen control keyboard. The kV value that has been
automatically determined is saved for subsequent fluoroscopic
initiations, and the system switches to the manual mode.
• Select the desired kV and mA values using the kV Up Arrow and
Down Arrow buttons located on the Mobile stand control keyboard.
Each time you press an arrow button, the value is increased/decreased
by 1 kV, and the mA follows the preset kV/mA curve for the selected
anatomical program selected.
• Initiate radiation.
To deactivate the manual exposure rate setting mode, do the following:
• Press the Manual Exposure button on the mobile stand control
keyboard or on the DeskView touch screen.
