Which of the following is a practical consideration for large animal radiography?

Most are done with unconscious animals

More people are needed in the controlled area during the procedure (correct)

Only one person is required to operate the machine

Horizontal beams have lower exposures than in small animals

What is the height of the X-ray beam during large animal radiography?

At the level of the animal's head

At the level of the animal handler's waist

At the level of the animal handler's head (correct)

What is the purpose of using protective clothing and plate holders in large animal radiography?

To ensure accurate positioning of the animal

To prevent the animal from moving during the procedure

What are some practicalities to consider for large animal radiography?

Machine operator, plate holder and animal handler often required; often done at client premises; use of horizontal beam and large patients requires careful attention to safety, planning and good technique; more people in controlled area during procedure; need to think about where the beam is going before and after leaving the probe; higher exposures than used in small animals - travel further, more scatter; need well sedated and restrained animal; height of beam is at mid level of the handlers; must use protective clothing and plate holders where possible Signup and view all the answers

What are some practical difficulties in making radiographic procedures safe?
