TCDHA Radiography Theory Midterm review With Questions And 100% SURE ANSWERS
Terms in this set (170)
- form of secondary radiation
- result of xray photon deflected in all directions travelling to all parts of client's body and to
Scatter radiation
all areas of the op
- detrimental to client and radiographer
- Evidence of ionization
Compton scatter - xra photon collides w outer shell + gives up part of its energy to eject electron from it's orbit
- ejected electron is known as compton or recoil electron
- unmodified scatter
- when low energy photons interact with outer shell electron
Coherent scatter - no changes in atom
- no ionization
- 8% percent of xradiation
1/9
, - projects from tube head and used to direct xradiation to client's face
TCDHA Radiography Theory Midterm review
- refers to totaly quantity of xrays produced
Milliamperage - controls film blackening
Higher mA, darker the xray
kV Higher kVp = higher penetrating power
Aka wolfram
Tungsten target Attached to copper stem
Speeding electrons hit the tungsten target
Aluminum filter Filters out long wavelengths with poor penetration power
The production of ions, or the process of converting an atom into ions
Ionization
Deals with only electrons
Primary Radiation - xray thats produced at target or anode and exit the tubehead
x-radiation that is created when the primary beam interacts with matter.
Secondary Radiation
Eg. Soft tissue of head, cranial bones and teeth
- secondary radiation
Scatter radiation - result of xray photon deflected in all directions travelling to all parts of the clien'ts body and
to all areas of the operatory
- electrostatic force or attraction between the positive nucleus and the negative electrons
Electrical force (Binding force)
- k shell is strongest
Negative charge terminal
Cathode
Hotter the filament. More electrons produced
Positive charge terminal
Anode Mostly made up of copper rod
Copper like oil used to dissipate heat
Anything that has mass and occupies space
Matter When matter is altered, energy results
All matter
118 is composed
different of atoms
atoms identified (periodic table)
2/9
