1. When using a stepwedge to check calibration reproducibility, you should:
a) Keep the same kV, but change the mA selection, adjusting the time to obtain the same
mAs.
b) Using the same kV and mA station, make a series of five exposures, exposing a fresh area of the film each time.
c) Using the same kV setting, make two exposures, first on the fine focus, then on the large
focus. Use the same mAs setting, exposing a fresh area of film each time.
2. The Bucky table lateral movement lock suddenly has reduced grip, and does not hold the table firmly in position.You decide to:
a) Look for a faulty fuse.
b) Request an electrician to boost the voltage to the lock coils.
