Q

Part Position:

2
Q

Patient Position:

A

Patient Position:

7
Q

8
Q

A

COLLIMATION:

  • a mechanism (inside the tube) utilized to limit the exposure field
  • required to be seen on the film in some states
9
Q

CEPHALAD:

A

  • towards the right or left side of the body
14
Q

Medial:

- angle of body parts is decreased

16
Q

Extension:

A

Extension:

  • angle of body parts is increased
17
Q

MARKERS

A
18
Q

Single Letter Markers:

A

Single Letter Markers:

  • the single letter marker indicates the patient’s appropriate side of the body part closest to the film during exposure
19
Q

Multiple Letter Markers:

A

Multiple Letter Markers:

  • the marker will indicate the body part closest to the film during the exposure.
    Ex: RAO, RPO
20
Q

Placement of Marker:

A

Placement of Marker:

  • never obstruct any anatomical structure with a marker
  • carefully place markers so that they are not COLLIMATION out of the exposed area of the film
  • DO NOT PLACE MARKERS IN AREA OF NAMEPLATE
21
Q

Mitchell Markers:

A

Mitchell Markers:

  • markers with Mercury Balls inside a small dome or bubble
  • when the BUCKY is upright the balls will be located at the BOTTOM of the dome
  • when the BUCKY is PARALLEL to the FLOOR, the balls will be CENTRALLY located
22
