which component of the tubehead aims and shapes the beam?

what are the electrons are generated by?

what is the purpose of the anode?

what part of the x-ray beam is most detrimental to the patient and operator

when kvp is increased what happens to the xray beam?

low contrast film greater than or equal to 90 kvp is useful for?

_____ regulates the quantity of electrons produced at the cathode

10 mA, exposure 3 seconds = 30 mA sec. if mA is increased to 15, time = ____ seconds to
maintain the same density (30 mA sec)

what is affected if the mA changes and the kvp is the same setting

what percent of electron energy is converted to x-rays

what does collimation do?

radio intense screens are used to

how many impulses are in one second in an x-ray timer?

secondary (scatter) originates when?

source to film distance increased without changing exposure time =

increase of mA and same kvp=

Which can occur when x-ray photons interact with matter and is responsible for producing densities on film that make radiography possible?

________ the emission and propagation of energy through space or material in the form of waves or stream of particles
________ the process by which certain unstable atoms or elements undergo spontaneous disintegrationin an effort to attain a more balanced nuclear state.
