Answer to Question 1

shadow shield

Rationale: Shadow shields have a piece of leaded material attached to an arm that can be attached to the tube head. The material will cast a shadow as adjusted to the correct anatomic location.

Answer to Question 2

radiolucent contrast

Rationale: A radiolucent contrast is a negative agent that has a low atomic number. Radiolucent contrast agents may be introduced in certain exams to create a double contrast effect on the image. A radiolucent contrast will appear dark on the radiograph.
