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

x-ray tube

The control of 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 (mA) by the exposure time (s).

The primary components of the x-ray tube are the:

anode and cathode

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

collimator assembly.

When using photostimulable phosphor technology (PSP):

the x-ray exposure is contained in "electron traps" in the phosphor layer.

All of the following are features of radiographic tables EXCEPT:

motorized, variable height adjustment

four-way "floating" tabletop mobility

tabletop materials that are high in x-ray attenuation

electric locks on tabletop motions

tabletop materials that are high in x-ray attenuation

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

tube stand or overhead tubecrane assembly

Pivoting the x-ray tube assembly at the point at which it is attached to its transverse support is

tube angulation

All of the following are true of fluoroscopy EXCEPT:

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

it permits "real time" imaging of dynamic patient functions

modern day fluoroscopy systems record images electronically rather than using cassetts

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

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