RADIOGRAPHIC OPERATION
140
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 Time 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.
2.
Position the patient for the examination.
3.
Select the "workstation" and technique parameters using the RAD
controls on the NX Station or on the DX-D Console.
4.
Instruct patient to maintain the required position. Prepare the X-ray Tube
by pressing the handswitch button to the "Prep" position and maintain it
until the "Ready" indicator is illuminated.
5.
Instruct patient to remain still and to hold their breath as required, then
make the X-ray exposure by pressing the handswitch button fully to the
"Exp" position and maintain it throughout the exposure. The "X-ray On"
indicator will light and an alarm will sound during the exposure.
6.
When the exposure is finished, release the handswitch button.
7.
Repeat the procedure if additional exposures are desired.
