Projections and Positions

Question 1

The term defined as the path of central ray as it exits the x-ray tube and goes through the patient to the IR is called a what?

Answer 1

Projection

Question 2

During this projection a perpendicular central ray enters the anterior body surface and exits the posterior body surface is known as what projection?

Answer 2

Anteroposterior-AP

Question 3

During this projection a perpendicular central ray enters the posterior body and exiting the anterior body surface.

Answer 3

Posteroanterior-PA

Question 4

During this projection, there is longitudinal angulation of the central ray with the long axis of the body or a specific body part.

Answer 4

Axial projection

Question 5

This term refers to all projections in which the longitudinal angulation between the central ray and the long axis of the body part is 10 degrees or more.

Answer 5

Axial

Question 6

Occasionally the central ray is directed toward the outer margin of a curved body surface to profile a body part just under the surface and project it free of superimposition during this projection.

Answer 6

Tangential

Question 7

During this projection, a perpendicular central ray enters one side of the body or body part, passes transversely along the coronal plane and exits on the opposite side.

Answer 7

Lateral projection

Question 8

During this projection, the central ray enters the body or body part from a side angle following an oblique plane.

Answer 8

Oblique projection

Question 9

If the central ray enters the anterior surface and exits the opposite posterior surface, it is known as what projection?

Answer 9

AP oblique projection

Question 10

If it enters the posterior surface and exits anteriorly, it is known as what projection?

Answer 10

PA oblique projection

Question 11

The overall posture of the patient or the general body position is termed as what?

Answer 11

Position

Question 12

Erect or marked by a vertical position.

Answer 12

Upright

Question 13

Upright position in which the patient is sitting or stool.

Answer 13

Seated

Question 14

Lying on the back

Answer 14

Supine

Question 15

Lying face down

Answer 15

Prone

Question 16

Supine position with the head tilted downward

Answer 16

Question 17

Supine position with the head higher thant the feet.

Answer 17

Fowler’s position

Question 18

General term referring to lying down in any position.

Answer 18

Recumbent

Question 19

A recumbent position with the patient lying on the left anterior side (semiprone) with the left leg extended and the right knee and thigh partially flexed.

Answer 19

Sim’s position

Question 20

A supine position with the knees and hip flexed and thighs abducted and rotated externally, supported by ankle supports.

Answer 20

Lithotomy position

Question 21

This position refers to the side of the patient that is placed closest to the IR.

Answer 21

Lateral position

Question 22

This position is achieved when the entire body or body part is rotated so that the coronal plane is not parallel with the radiographic table or IR.

Answer 22

Oblique position

Question 23

Term used to indicate that the patient is lying down and that the central ray is horizontal and parallel with the floor

Answer 23

Decubitus position

Question 24

This position is achieved by having the patient lean backward while in the upright body position so that the shoulders are in contact with the IR.

Answer 24

Lordotic position

Question 25

This term is used to describe the body part as seen by the IR.

Answer 25

View

Question 26

This term describes the specific radiographic projection that the individual developed.

Answer 26
