questions and answers 2026\2027 A+ Grade
Which side of the xray tube is negative?
- correct answer cathode
Which side of the X-ray tube is positive?
- correct answer anode
What is the role of the glass envelope
- correct answer maintain the vacuum between the cathode and anode; so electrons from the filament
do not collide with atoms of gas
What is the role of tube housing?
- correct answer Supports and protects the tube, restricts leakage, and provides insulation
What end of the tube has the filament and focusing cup?
- correct answer cathode
What are the types of anodes
- correct answer stationary and rotating
Stationary anodes:
- correct answer Electrons always hit the same spot building heat that can cause damage
rotating anode
- correct answer Spreads the heat produced from X-ray reaction over a large area of the anode,
extending tube life
,What is the anode made of?
- correct answer tungsten and rhenium
Why is tungsten used as a target material?
- correct answer 1. high atomic number (74)
2. high melting point
What is the stator?
- correct answer Magnetic motor that induces the rotor at high speed
What does the rotor do?
- correct answer rotates the anode
What do bearings do?
- correct answer Low friction spheres that allow for rotation for motor
Define anode heel effect
- correct answer Variation in x-ray intensity between anode and cathode sides of the tube due to the
angle of the anode
why is the beam more intense on the cathode end?
- correct answer Beam is angled so less of beam comes out on anode side
If the degree of anode angle DECREASES - will that increase or decrease the anode heel effect?
- correct answer increase
Which is larger, the actual focal spot or the effective focal spot?
- correct answer actual focal spot
Where is the actual focal spot located?
- correct answer At the anode
,Which focal spot goes towards the patient?
- correct answer Effective
If you decrease anode angle, how will that affect the effective focal spot?
- correct answer The effective focal spot will decrease
Off focus radiation:
- correct answer Refers to the emission of x-ray photons that originate outside of the anode focal spot
or
Tube Loading (Heat Units):
- correct answer A calculation of the total heat produced during an x-ray exposure
series circuit
- correct answer An electric circuit with only one path through which charge can flow.
-if one component fails the whole circuit fails
parallel circuit
- correct answer A circuit that contains more than one path for current flow.
- constant voltage
- if one component fails, the circuit continues on
Ohm's Law
- correct answer current is directly proportional to voltage and inversely proportional to resistance
current
- correct answer The rate at which electrons flow
Resistance
- correct answer The force that slows down electrons
Voltage
- correct answer The force pushing electrons through a circuit
, Components of the primary circuit
- correct answer - main power supply
- circuit breaker
- autotransformer
- kVp meter
- exposure timer
- primary side of the step up transformer has
Components of the secondary circuit
- correct answer - secondary side of step up transformer has more
- rectifier
- x-ray tube
components of filament circuit
- correct answer rheostat, step-down transformer, filaments
What is the incoming voltage coming into the circuit
- correct answer 220 volts AC
Which transformer comes first in the circuit
- correct answer autotransformer
What is the role of the autotransformer
- correct answer kV selector
The autotransformer works on what kind of induction?
- correct answer Self induction
What is the role of the step up transformer
- correct answer changes volts to kilovolts
