Radiographic Terms

Question 1

refers to the long axis of a structure or part (around which a rotating body turns or is arranged).In radiographic positioning, the term __ has been used to describe any angle of the CR of 10° or more along the long axis of the body or body part

Answer 1

Axial projection

Question 2

Are frequently performed for the shoulder and hip, where the cr enters below or inferiorly and exits above ir superiorly

Answer 2

Inferosuperior axial projection

Question 3

Performed on a special nasal bone projection where the cr enters above or superiorly and exits below or inferiorly

Answer 3

Superoinferior

Question 4

Means touching a curve or surface at only one point. This is a special used for the term projection to describe a projection that merely skims a body part to project that part into profile and away from other body structures

Answer 4

Tangential projection

Question 5

A specific ap chest projection for demonstrating apices of lungs. Also sometimes called apical lordotic projection

Answer 5

Ap axial projection-lordotic position

Question 6

A lat projection through the thorax. Requires a qualifiying positioning term (right or left lat projection) to indicate which shoulder is closes to ir and is being examined

Answer 6

Transthoracic lateral projection (right lateral position)

Question 7

Path of cr from dorsal (anterior) surface to the plantar (posterior) surface of foot

Answer 7

Dorsoplantar and plantodorsal projection

Question 8

Cr enters at cranial parietal bone and exits at atcanthion (junction of nose and upper lip)

Answer 8

parietoacanthial projection

Question 9

Cr enters at acanthion (junction of nose and upper lip) and exits at cranial parietal bone

Answer 9

Acanthioparietal projection

Question 10

Used for skull and mandible, cr enters below the chin, or mentum and exits at vertex or top of skull

Answer 10

Submentovertex (SMV) projection

Question 11

Used for skull and mandible, cr enters at vertex or top of skull below and exits the chin, or mentum

Answer 11

Verticosubmental (VSM) projection

Question 12

The goal of every technologist should be to take not just a “passable” radiograph but rather an optimal one that can be evaluated by a definable standard, as described under evaluation criteria.

Answer 12

POSITIONING PRINCIPLES

Question 13

Describes precisely what anatomic parts and structures should be clearly visualized on that image(radiograph).

Answer 13

Anatomy demonstrated

Question 14

Generally, evaluates four issues: (1) placement of body part in relationship to the IR, (2) positioning factors that are important for the projection, (3) correct centering of anatomy, and (4) collimation

Answer 14

Position

Question 15

Describes how exposure factors or technique (kilovoltage [kV], milliamperage [mA], and time) can be evaluated for optimum exposure for that body part. No motion is a priority, and a description of how the presence or absence of motion can be determined is listed. (Motion is included with exposure criteria because exposure time is the primary controlling factor for motion.)

Answer 15

Exposure

Question 16

A fourth area of evaluation involves image markers. Anatomic side markers, “Right” or “Left,” patient position, or time markers must be placed correctly before exposure so that they are not superimposed over essential anatomy.

Answer 16

Image markers

Question 17

minimum of two types of markers should be imprinted on every radiographic image. These are

Answer 17

patient identification and date and anatomic side markers.

Question 18

ARE DEFINED AS PROJECTIONS COMMONLY TAKEN ON PATIENTS WHO CAN COOPERATE FULLY .

Answer 18

Routine projections

Question 19

These are defined as projections most commonly taken to demonstrate better specific anatomic parts or certain pathologic conditions or projections that may be necessary for patients who cannot cooperate fully.

Answer 19

Special projections
