Radposi Terms

Question 1

An image of a patient’s anatomic part(s), as produced by the action of x-rays on an image receptor

Answer 1

Radiograph

Question 2

The process and procedures of producing a radiograph.

Answer 2

Radiography

Question 3

The device that captures the radiographic image that exits the patient; refers to both film- screen cassettes and digital acquisition devices.

Answer 3

Image receptor

Question 4

Refers to the center-most portion of the x-ray beam emitted from the x-ray tube; the portion of the x-ray beam that has the least divergence.

Answer 4

Central ray

Question 5

Projection is a positioning term that describes the direction or path of the CR of the x-ray beam as it passes through the patient, projecting an image onto the IR.

Answer 5

Radiographic projection

Question 6

refers to a projection of the CR from posterior to anterior.

Answer 6

POSTEROANTERIOR PROJECTION

Question 7

projection refers to a projection of CR from anterior to posterior, the opposite of PA.

Answer 7

ANTEROPOSTERIOR PROJECTION

Question 8

projection of the upper or lower limb that is rotated is called “oblique.” This is not a true AP projection and must also include a qualifying term that indicates which way it is rotated, such as medial or lateral rotation

Answer 8

Ap oblique projection

Question 9

It must also include a qualifying term that indicates which way it is rotated. With a PA oblique projection, the CR enters the posterior surface and exits the anteriorsurface of the body or body part.

Answer 9

Pa oblique projection

Question 10

A lateral projection is described by the path of the CR. Two examples are the __ of the ankle and the __ of the wrist. The medial and lateral sides are determined with the patient in the anatomic position.

Answer 10

Mediolateral and lateromedial projection

Question 11

Lying on back, facing upward

Answer 11

Supine

Question 12

Lying on abdomen, facing downward (head may be turned to one side).

Answer 12

Prone

Question 13

An upright position, to stand or sit

Answer 13

Erect

Question 14

Lying down in any position (prone, supine, or on side).

Answer 14

Recumbent

Question 15

Lying on back (supine).

Answer 15

Dorsal recumbent

Question 16

Lying face down (prone).

Answer 16

Ventral recumbent

Question 17

Lying on side (right or left)

Answer 17

Lateral recumbent

Question 18

recumbent position with the body tilted with the head lower than the feet.

Answer 18

Trendelenburg position

Question 19

A recumbent position with the body tilted with the head higher than the feet.

Answer 19

Fowlers position

Question 20

A recumbent oblique position with the patient lying on the left anterior side, with the right knee and thigh flexed and the left arm extended down behind the back.

Answer 20

Sims position

Question 21

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

Answer 21

Lithotomy position

Question 22

refers to the side of, or a side view. Specific lateral positions described by the part closest to the IR or the body part from which the CR exits. A true lateral position is always 90°, or perpendicular, or at a right angle, to a true AP or PA projection. If it is not a true lateral, it is an oblique position.

Answer 22

Lateral position

Question 23

refers to an angled position in which neither the sagittal nor the coronal body plane is perpendicular or at a right angle to the
IR. Oblique body positions of the thorax, abdomen, or pelvis are described by the part closest to the IR or the body part from which the CR exits.

Answer 23

Oblique position

Question 24

This body position, meaning to lie on a horizontal surface, is designated according to the surface on which the body is resting. This term describes a patient who is lying on one of the following body surfaces: back (dorsal), front (ventral), or side(right or left lateral). In radiographic positioning, decubitus is always performed with the central ray horizontal. Decubitus positions are essential for detectingair-fluid levels or free air in a body cavity such as the chest or abdomen, where the air rises to the uppermost part of the body cavity

Answer 24

Decubitus position

Question 25

decreases the angle of the joint.

Answer 25

Flexion

Question 26

increases the angle as the body part moves from a flexed to a straightened position. This is true for the knee, elbow, and wrist joints.

Answer 26

Extension

Question 27

Extending a joint beyond the straight or neutral position.

Answer 27

Hyperextension

Question 28

literally means “to turn aside” or “to turn away from the standard or course.” Ulnar deviation is to turn or bend the hand and wrist from the natural position toward the ulnar side, and radial deviation is toward the radial side of the wrist

Answer 28

Deviation

Question 29

to decrease the angle (flex) between the dorsum (top of foot) and the lower leg, moving foot and toes upward.

Answer 29

Dorsiflexion of foot

Question 30

Extending the ankle joint, moving foot and toes downward from the normal position; flexing or decreasing the angle toward the plantar (posterior) surface of the foot.

Answer 30

Plantar flexion of foot

Question 31

is an outward stress movement of the foot at the ankle joint.

Answer 31

Eversion

Question 32

is an inward stress movement of the foot as applied to the foot without rotation of the leg.

Answer 32

Inversion

Question 33

is a movement backward or the condition of being drawn back.

Answer 33

Retraction

Question 34

a rotation or turning of a body part with movement of the anterior aspect of the part toward the inside, or median, plane.

Answer 34

Medial rotation

Question 35

a rotation of an anterior body part toward the outside, or away from the median plane.

Answer 35

Lateral rotation

Question 36

the lateral movement of the arm or leg away from the body. Another application of this term is the abduction of the fingers or toes, which means spreading them apart.

Answer 36

Abduction

Question 37

is a movement of arm or leg toward the body, to draw toward a center or medial line. Adduction of the fingers or toes means moving them together or toward each other.

Answer 37
