5.4 AEC OPERATION
The proper use of AEC requires accurate patient positioning. For examination
using AEC, the operator will need to select the desired AEC parameters as
follows:
1. Make sure that the X-ray Tube is properly warmed-up.
2. Position the patient for the examination.
3. Select the “ DR Detector ” workstation and enter in AEC mode by
selecting at least one Area Detector “ Field ” on the Software Console.
4. If required, choose another “Sensitivity” and adjust the “ Density ” setting
(“ 0 ” is the normal setting).
5. Select the technique parameters using the Generator controls on the
Console.
6. Continue with the radiographic operation. (Refer to Section 5.3 -- step 4.)
5.4.1 HOW TO VERIFY THE PROPER FUNCTIONING OF THE AUTOMATIC EXPOSURE
CONTROL
This procedure is not mandatory, it is only a method so that the
operator can verify the proper functioning of the Automatic
Exposure Control.
1. Ensure that X-ray Tube has been properly warmed up.
2. Align and center the X-Ray Tube to the DR Detector.
3. Set a SID of 1 m (40”).
4. Collimate the X-Ray beam so that it completely covers all three Ion
Chambers (Left, Center and Right).
5. Place on the Table-Top and within the X-Ray beam a homogeneous
phantom (e.g. a bucket with 10 cm of water) that covers all three Ion
Chambers.
6. Set a technique, for example: 70 kVp, 250 mA, 1.0 second back-up time.
