Mobile Radiography and Equipment
1. Maximum Incline for Mobile X-ray Unit:
- A battery-powered, battery-operated mobile X-ray unit can climb a maximum incline of 7 degrees.
2. Type of Mobile Radiography Unit:
- The type of mobile radiography X-ray unit that is self-propelled is battery operated, battery driven
source.
3. C-arm Usage:
- False Statement: C-arms are most commonly stationary fluoro units used in surgery.
- True Statement: The C-arm fluoro unit can be rotated a minimum of 180 degrees.
- True Statement: Digital C-arm units can store images on videotape or computer hard disk memory.
- Road Mapping: Term for the process of holding one image on the C-arm monitor while also providing
continuous fluoroscopy.
- False Statement: AP with the X-ray tube placed directly above anatomy during a C-arm procedure is
NOT recommended to minimize OID; PA is recommended.
### Fractures
1. Types of Fractures:
- Hangman's fracture: Fracture through the pedicles of C2.
- Monteggia fracture: Fracture of the proximal half of the ulna with dislocation of the radial head.
- Pathologic fracture: Resulting from a disease process.
- Chip fracture: Resulting in an isolated bone fragment.
- Nursemaid's elbow: Subluxation of the radial head in a child.
- Bennett's fracture: Fracture along the base of the 1st metacarpal.
- Baseball fracture: Fracture of the distal phalanx with the finger extended.
- Stress or fatigue fracture: Also called a march fracture.
- Hutchinson's fracture: Also called a chauffeur's fracture (fracture of the styloid process of the radial
bone).
, ### Imaging Considerations and Safety
1. Projections for Trauma Studies:
- True Statement: Any trauma study requires at least two projections as close to 90 degrees opposite
from each other.
- True Statement: On an initial study of a long bone, both joints should be included for each projection.
- False Statement: Collimation on trauma cases can lead to cutoff of key anatomy and pathology;
therefore, it should NOT be limited to the size of the IR.
2. Distance from X-ray Tube:
- The technologist must be at least 6 feet (1.8 m) from the X-ray tube during a mobile radiographic
procedure.
3. Radiation Exposure:
- False Statement: The exposure dose is greater on the II side than on the X-ray tube side with the C-
arm in the horizontal configuration.
- False Statement: A 30-degree tilt of the C-arm from the vertical perspective does NOT increase the
dose by a factor of 3 to the head and neck region; it is actually by a factor of 4.
4. Safety Precautions:
- Before returning a trauma patient to the ER following a radiographic procedure, the tech should
ensure side rails are up on the patient cart.
5. Trends in Imaging:
- True Statement: The number of angiographies of the aortic arch for trauma patients has declined due
to increased use of CT angiography.
### Joint Displacement Terminology
1. Dislocation or Luxation: Correct term for the displacement of a bone from a joint.
2. Subluxation: Correct term for a partial displacement.
3. Lack of Apposition: Fracture term where the ends of the fragments are aligned but pulled apart, not
making contact.
