true

8

True or False:

The Frankfort horizontal plane is also referred to as the midcoronal plane.

False

9

The direction or path of the central ray defines what positioning term:

Projection

10

The positioning term that describes the general and specific body position is:

position

11

True or False:

Oblique and lateral positions are described according to the side of the body closest to the image receptor.

True

12

True or False:

Decubitus positions always use a horizontal beam.

True

13

What is the name of the position in which the body is turned 90 degrees from a true anteroposterior (AP) or posteroanterior (PA) projection?

Lateral Position

14

A patient is erect with the back to the image receptor. The left side of the body is turned 45 degrees toward the image receptor. What is this position?

Dorsal Decubitus (left lateral)

17

The patient is erect with the right side of the body against the image receptor. The x-ray beam enters the left side of the body and exits the right side of the body. Which specific position has been performed?

Right Lateral

18

Plantar

27

Position in which head is lower than the feet

Trendelenburg

28

Posterior

29

What is the name of the projection in which the central ray enters the anterior surface and exits the posterior surface?

30

A projection using a CR angle of 10 degrees or more directed parallel along the long axis of the body or body part is termed a/an _______ projection.

axial

31

The specific position that demonstrates the apices of the lungs, without superimposition of the clavicles, is termed a/an ________ position.
