X-ray Production and Imaging Quiz

X-rays are produced when high-speed electrons strike the:

• Cathode

• Filament

• Anode target

• Grid

The process responsible for X-ray photon production is:

• Thermionic emission

• Bremsstrahlung and characteristic radiation

• Photoelectric absorption

• Scattering

The target material in an X-ray tube is usually made of:

• Copper

• Tungsten

• Aluminum

• Steel

The high melting point of tungsten is approximately:

• 1500°C

• 3400°C

• 4500°C

• 1000°C

The filament in an X-ray tube is made of:

• Tungsten

• Molybdenum

• Nickel

• Iron

Thermionic emission is the:

• Emission of photons from the target

• Boiling off of electrons from the filament

• Acceleration of electrons

• Deceleration of electrons

The focusing cup in the X-ray tube is made of:

• Lead

• Molybdenum

• Nickel

• Tungsten

The function of the focusing cup is to:

• Focus the X-ray beam

• Focus the electron stream

• Increase beam intensity

• Produce contrast

The energy of an X-ray photon is proportional to:

• Wavelength

• Frequency

• Filament current

• Exposure time

The quantity of X-rays produced depends on:

• kVp

• mA and exposure time

• Filtration

• Focal spot
