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.
