Avulsion
T/F The maximum fluoroscopic KV of most C – arms is 120 KVP
True
_____ is used to create an x-ray beam that activates at timed increments to reduce exposure during C – arm fluoroscopy
Pulse mode
A self propelled, battery, driven mobile x-ray unit will generally go up a Maximum incline of
7°
What is the minimum distance a technologist should stand away from the x-ray tube during an exposure when using a mobile x-ray unit
6 feet
Which one of the three cardinal rules of radiation protection is the most effective means of reducing exposure during mobile and surgical procedures
Distance
Which of the C-arm orientations is generally results in the greatest exposure to the operators, head region if the distance from the patient is unchanged
AP projection (X-ray tube above anatomy)
A radiographer receives 400mR/hr standing on 1 foot from a C-arm fluoroscopy unit. What is the exposure rate if the radiographer moves to a distance of 3 feet?
25 to 50mR/hr
Where should the operator for surgeon stand when using a C arm fluoroscopy unit in a horizontal central ray position
Intensifier end of the C-arm
A 30° tilt of the C-arm x-ray tube from the vertical position will increase radiation exposure to the face and neck region of the operator standing next to the C-arm by approximately a factor of
4
A patient enters the emergency department with a possible pneumothorax of the right long. The patient is unable to stand or sit erect. Which specific position should be performed to diagnose this condition.
Left lateral decub
