1
, What is the effect of excessive kVp on image contrast?
✔✔ Reduces contrast due to excessive penetration
Why is proper patient positioning important in radiography?
✔✔ To ensure accurate anatomy visualization and minimize repeats
Which factor primarily controls X-ray beam quantity?
✔✔ mAs
What is the purpose of the grid cutoff phenomenon?
