RAD 100 - Ch 8 Radiographic & Fluoroscopic Equipment - Review Questions

The component of the radiographic system that produces radiation is the:

x-ray tube

The selection of radiographic exposure factors such as mAs and kVp is performed at the operator:

control console

The quantity of electrons for x-ray exposure is determined by the mAs. This is calculated by:

multiplying the milliamperage by the exposure time.

The primary components of the x-ray tube important to x-ray production are the:

anode and cathode

The component that controls the size and shape of the x-ray exposure field is the:

collimator assembly.

True digital image receptors are referred to as:

flat panel detectors

All of the following are typical features of radiographic tables EXCEPT:

a. they have motorized, variable height adjustment.

b. they permit four-way "floating" tabletop mobility.

c. the tabletop materials offer high attenuation to lower patient dose.

d. they have electric locks on tabletop motions.

c. the tabletop materials offer high attenuation to lower patient dose.

The component that supports and permits the x-ray tube to be moved in different directions is the:

tube stand or overhead tube crane assembly.

In a fluoroscopic system, the surface or face of the fluoroscopic detector is considered the:

primary barrier

All of the following are true of fluoroscopy EXCEPT:

a. the lead protective apron attached to the fluoroscopic carriage is of little value in reducing operator dose.

b. it permits "real-time" imaging of dynamic patient functions.

c. modern day fluoroscopy systems record images elec-tronically rather than using cassettes.

d. dose reduction features such as last image hold (LIH), pulsed fluoroscopy, and electronic shuttering are essential.

a. the lead protective apron attached to the fluoroscopic carriage is of little value in reducing operator dose.
