Question

The anode heel effect is more pronounced :

A with rotating anodes.
when the collimator is not completely ope
C when the collimator is open wide
D a the anode

Answer 1

At the Anode.

Step-by-step explanation:

Anode heel effect is the lower field intensity that occur at the anode compare to the cathode which is as a result of lower x-ray emissions from the target material at angles perpendicular to the electron beam.

It occur at the anode because the effect is stem when x-rays photons is absorbed before they leave the anode where they are produced.
