RADPRO MODULE 6 Flashcards
what are the 3 things produce in the interaction of electron in the x-ray tube
anode heat, characteristic rad, and bremsstrahlung
what will happen in the quantity if you incre the mAs
increase
what will happen to the quality if you increase the mAs or current
no change in quality
what will happen to the quantity if oyu increase the kvp
increase
what will happen to the quality if you increase the kvp
increase
what will happen to the quality if you add filtration
increase
what will happen to the quantitiy if you increase the filtration
decrease
what will happen to the quantity if you increase the voltage ripple
decrease
what will happen to the quality if oyu increase the voltage ripple
decrease
The primary function of the x-ray imaging system
accelerate electrons
3 principal parts of x-ray imaging system
operating system, high voltage generator, and the x-ray tube
The distance between the filament and the x-ray tube target is only approximately
1 cm
Electrons traveling from cathode to anode constitute the x-ray tube current
projectile electron
When these projectile electrons hit the heavy metal atoms of the x-ray tube target, they transfer their
kinetic energy
the kinetic energy from the electron is converted into______
thermal heat, electromagnetic energy (infrared and xray
responsible for most of the heat generated in the anodes of x-ray tubes.
excitation and return of outer shell electrons
how many percent of kinetic energy is converted to heat
99
how many kinetic energy is converted into x-ray
1%
what will happen to the heat production if you increase kVp
increase
what will happen to the x-ray production if you increase kVp
increase
what will be produce if the projectile electron interacts with an inner-shell electron of the target atom rather than with an outer shell electron
characteristic x-ray
only ___ of tungsten are useful for imaginge
k-characteristics x-rays
the energy of the x-ray depends on what??
the atomic number of target element
A projectile electron that completely avoids the orbital electrons as it passes through a target atom may come sufficiently close to the nucleus of the atom to come under the influence of its electric field.
Bremsstrahlung Radiation
Bremsstrahlung is a German word that means
“slowed-down radiation.”
*In the diagnostic range, most x-rays
bremsstrahlung x-rays
to the range of types of balls or values of any quantity such as x-rays.
spectrum
contains all possible values
continuous spectrum
contains only specific values
discrete spectrum
