Answer to Question 1

a phantom image

Rationale: A phantom image can occur with CR imaging if the laser in the processor is not strong enough to erase the latent image from a previous exam.

Answer to Question 2

the posterior rib margin is superimposed and the intervertebral foramina are open

Rationale: A true lateral t-spine is determined when the posterior rib margins are superimposed and the intervertebral foramina are open.
