9.3 RADIOGRAPHIC OPERATION
RAD operation can be performed in the following modes:
Three point control by selecting kVp, mA and Exposure Time
independently.
Two point control by selecting kVp and mAs independently. mAs
selection sets the maximum mA available for the selected Focal Spot
and the respective Exposure Time. In this control mode, when kVp value
is increased, the Generator will automatically look for the adequate
combination of mA and Exposure T ime factors to avoid the “Tube
Overload” warning, keeping constant mAs.
One point control by selecting kVp with AEC operations.
Anatomical Programs (APR).
A typical RAD examination sequence is as indicated below:
1. Make sure that the X-ray Tube to be used is properly warmed-up.

3. Position the patient for the examination.
4. Select the “workstation” and technique parameters using the RAD
controls on the NX Station or on the Ceiling Suspension Control Console.
5. Instruct the patient to maintain the required position. Prepare the X-ray
T ube by pressing the handswitch button to the “Prep” position and
maintain it until the “Ready” indicator is illuminated.
