Answer to Question 1
the effects of absorption qualities upon tissues and radiographic appearances
Rationale: Tissues of different atomic numbers will either absorb the beam or allow the beam to pass easily through. Tissues with high atomic number such as bone will absorb most of the beam, resulting in white image components. Tissues easily penetrated will appear darker.
Answer to Question 2
collimate
