Use these steps to perform the table Bucky AEC calibration.
Step Action
IF THE AEC BOARD BEING CALIBRATED HAS SHORT AEC TIME COMPENSATION POTENTIOMETERS, THE SHORT
EXPOSURE TIME COMPENSATION MUST FIRST BE DISABLED.
TO DO THIS, ADJUST ALL SHORT AEC EXPOSURE TIME COMPENSATION POTS TO ZERO BY TURNING EACH OF
THESE POTENTIOMETERS FULLY CLOCKWISE. THESE ARE MULTI-TURN POTENTIOMETERS, AND MUST BE TURNED
BY AS MUCH AS 25 TURNS TO REACH THE ZERO-OHMS LIMIT.
FAILURE TO PRESET THESE POTS WILL RESULT IN DIFFICULTY IN PERFORMING AEC CALIBRATION.
1.
Set up the X-ray tube stand as shown in figure 3D-5.
2.
Align the tube stand and table Bucky such that the central ray is centered relative to the image receptor.
