Bushong Chapter 4 and 5
Another word for electromagnetic induction is - answer mutual induction
Autotransformer defined - answer Works on the principle of electromagnetic induction.
can be single winding, one winding and one core has a number of connections along
the way.
What does an auto transformer allow us to do - answer Choose a variable secondary
transformer
All x ray tubes have _________. transformers – answer AUTO
Autotransformer laws for voltage - answer Voltage secondary divided by voltage primary
is equal to number of turns secondary divided by number of turns primary.
Vs/Vp=Ns/Np
Autotransformer law for current - answerAmperage primary divided by amperage
secondary is equal to number of turns secondary divided by number of turns primary.
amperage is expressed as an I
Ip/Is= Ns/Np
X ray tube converts energy from what kind to what kind? - answerKinetic energy to
electromagnetic energy
Purpose of the x ray tube is to provide a - answercontrolled flow of electrons intense
enough to produce an X-ray beam appropriate for imaging
#xray tube support methods - answer- ceiling support system
-floor to ceiling support system
-c arm support system
What are the three main components of an x ray imaging system - answer- Tuve
-Operating console
-High Voltage Generator
Ion - answerCharged particle
Ionizing radiation - answerCapable of ionizing matter
, AEC - answerAutomatic exposure control, counts how many ionizations will occur and
shuts the exposure down once the desired amount is reached
Most x ray tubes operate at - answer220 volts
Line compensator does what? - answerOn modern machines the line compensates
automatically compensates for variation in voltage.
+++++power companies are not capable of supplying a reliable continuous 220 voltage,
may vary by up to 5 percent++++
What does a diode do? - answerAllows current flow in one direction
What does a high Kvp do? - answerCreates the electric potential/ potential difference for
repelling electrons from the cathode to anode.
What does KVP determine? - answerQuality and penetrability of the x ray beam.
Filament Circuit defined - answerConnections to the autotransformer provide voltage for
the filament circuit.
-low voltage, higher current (A)
This heats the filament to boil off electrons.
What dies a filament do? - answerHeats up to create electrons, the larger the filament
the more electrons and more exposure.
What amperes do filaments operate at? - answer3-6 A
The hotter the temperature of the filament the ___________ the number of electrons
are emitted. - answerHigher
Cathode side is the ____________ side - answerFilament
Control of mA - answerThe number of electrons emitted by the filament is determined
by the temperature of the filament
Adjusting Current - answerPrecision Resistors results in fixed stations that provide the
tube currents of 100 ma, 200ma ,300 ma ect. X ray tube is not continously available
Control of mA - answerThe number of electrons emitted by the filament is determined
by the temperature of the filament.
Cathode side is the ____________ side - answerFilament
