Pregnant lady to do x-ray at the level of the kidney assuming Automatic exposure control is used, what is the most appropriate step to
reduce dose:
A) Cover the abdomen with lead
B) Increase Kvp will lead to decrease mAs by the AEC.
C) Put the patient in prone position
D) Collimate the image to the needed organ
D) Collimate the image to the needed organ
Answer: D
Notes:
- Increasing the KVP will increase the scatter plus you will be covering the whole abdomen
which will affect the fetus thus collimating the image will cover less surface which leads to
less radiation.
