1. Automatic Exposure control

A device programmed to terminate the radiographic exposure timer, aka
automated exposure device.

2. automatic exposure device

A device programmed to terminate the radiographic exposure timer, aka
automatic exposure control.

4. compression band

A piece of equipment used to restrain a patient or compress abdominal issues.

5. computed tomography unit

specialized radiography equipment that allows the taking of sectional images.

6. diagnostic

methods used to determine the source or cause of a disease, disorder,
or traumatic injury.

7. exposure switch

A remote control device that permits current flow through the circuit.

8. filament circuit

Supplies the filament of the x-ray tube with property of modified power.

9. fixed

A piece of equipment that remains in one place and is not moveable

10. floor suspension system

A type of radiography unit that uses a tube support column mounted on
the floor.

11. floor to ceiling suspension system

A type of radiography unit that uses a pair of rails for longitudinal positioning

12. footboard

A piece of equipment used with a tilting table that allows the
patient to stand when the table is upright.

13. handgrip

A piece of equipment that allows the patient to grip when the table
is being tilted for added support and reassurance.

14. head unit

Specialized radiography equipment used to conduct cranial studies.

15. incoming-line current

The alternating current that is supplied to buildings; usually
supplied in three phase power cycle; also called the mains.

16. ionization chamber

An automatic exposure control device used to terminate the exposure
after a desired exposure has been reached.

17. main circuit

Supplies the x-ray tube with properly modified power.

18. mains

The alternating current is supplied to buildings; usually supplied in
three phase power cycle, also called incoming -line current.

19. main switch

The switch that generates the power to the x-ray tube.

20. mammography unit

Specialised radiography equipment for studies and imaging of the
breast tissues.

21. milliampere-second timer

A device used in falling -load generators and some capacitor units to
monitor the product of mA and time on the secondary side of the
high-voltage step-up transformer.

22. minimum reaction time

The length of time necessary for the AEC to respond to the radiation
and the generator to terminate the exposure.

23. mobile system

A type of radiography equipment that can be brought to the patient
anywhere the patient might be.

24. multiphase power

The combination of several waveforms of current slightly out of step
with one another.

25. overhead suspension system

A type of radiography unit that allows control of longitudinal and
transverse positioning as well as vertical distance.

26. panoramic dental and facial unit

Specialized radiography equipment for combined tomography of facial
and dental structures.

27. phototimers

Often used to describe all automatic exposure controls, this type of
AES os rarely used in modern radiography.

28. shoulder support

A piece of equipment that keeps the patient from sliding off the
table when the table is tilted head down.

29. simulator unit

Specialized radiography equipment that allows verification of
radiation therapy prior to actual treatment.

31. single phase power

Power supply that allows the potential difference to drop to zero
with every change in the direction of current flow.

32. therapeutic

Methods used to treat and rehabilitate a disease, disorder, or
traumatic injury.

33. tilting

A piece of equipment that is moveable and can be angled according to need.

34. timer

Device used to end the exposure at an accurately measured preset time.

35. tomography unit

Specialized radiography equipment that allows movement in an arc
during exposure.

36. urological unit

Specialized radiography equipment that allows study of the urological
and genital structures.

37. voltage ripple

The net voltage produced during full wave rectification.
