Trauma and Mobile Radiography Positioning Principles

Fill-in-the-blank flashcards covering trauma and mobile radiography positioning principles, adaptation, two-projection requirements, documentation, and exceptions.

The primary difference between trauma/mobile radiography positioning and routine general radiography is __.

adaptation

Trauma radiography generally requires two projections at 90 degrees with true CR and part IR alignment, also known as __ views.

orthogonal

Trauma radiography must include the entire __ on the IR image receptor.

structure or trauma area

In trauma radiography, safety must be maintained for the __.

patient, health care workers, and the public

The preferred projections are a true AP or PA and a true lateral, achieved by turning the body part or by __ the CR.

angling

CR and part IR alignment can be maintained even if the patient __.

cannot be turned or rotated

The AP projection is achieved by __ the CR and IR in the example of obtaining AP and lateral foot images without moving the lower limb.

angling

When adaptations are made, include information such as CR angle, projection of the beam, and __ (e.g., upright, semi-upright, or supine position).

IR placement and patient position

An exception to true AP and lateral occurs when obstructions such as __ prevent maintaining standard CR/part IR relationship.

splints, back supports, or traction bars

In such cases, you should attempt two projections near 90 degrees; only as a __ should you take a single projection.

last resort

If exceptions occur, leave a note explaining the __ in routine alignment in the patient's record and/or requisition.

reason for variance in CR and/or IR alignment

Generally, the IR is placed at right angles to the CR to minimize distortion, but some trauma cases may allow the CR–part relationship to be maintained while the IR–part relationship is not. This is an example of maintaining the CR–part relationship but not the __ relationship.

IR–part (IR image receptor) relationship

The AP axial oblique cervical spine example shows a patient supine with the IR flat; this may be acceptable in trauma due to __.
