Ch. 7 Imaging Equipment

The filament circuit is connected to the autotransformer and is responsible for delivering electrical current to the x-ray tube.​

• True

• False

Cassettes (old School) are stored in a lead lined passbox or bin and never leave the x-ray room.

• True

• False

High-voltage (secondary) circuits are used to change alternating current to direct current, or current flowing in one direction.​

• True

• False

The patient’s tissue volume is not a variable when selecting exposure factors.​

• True

• False

The control console is located behind a protective barrier or shield where the radiographer stands during the x-ray exposure.

• True

• False

In podiatry, most x-ray examinations of the foot and ankle are acquired with the patient in a (an):

• erect weight bearing position.

• supine position.

• prone position.

• dorsal recumbent.

To produce x-rays, the incoming line voltage must be controlled and changed to a direct current of many thousands of volts. This is accomplished by the:

• primary circuit.

• secondary circuit.

• high-voltage transformer.

• line voltage compensator.

In ENT medical practices, an upright radiographic head unit and a computed tomography (CT) system are used for x-ray examinations of the:

• clavicle and scapula.

• paranasal sinuses and facial bones.

• sternum.

• fibula and tibia.

Which of the following is a rotational or fixed part of a radiography system and includes an electrical system and controls for circuits, generators, fuses, switches and a collimator assembly?

• Bucky

• x-ray tube

• control console

• line voltage compensator

Which of the following is NOT considered a patient immobilization and safety device?

• ​shoulder support

• ​handgrip

• ​compression band

• ​Bucky
