Meaghan Piretti Comprehensive Resource To Help You Ace Exams Includes Frequently Tested Questions With ELABORATED 100% Correct COMPLETE SOLUTIONS Guaranteed Pass First Attempt!! Current Update!! What side of the x-ray tube positive Anode What side of the x-ray tube is negative Cathode What is the role of the glass envelope Containment and maintains the vacuum What is the role of the tube housing Prevents leakage and insulates What end of the tube has the filament and focusing cup Cathode What are the types of anodes Rotating and Stationary What is the anode made of Tungsten Why is Tungsten the chosen material for the anode Has a high atomic number meaning it has a high melting point Describe the induction motor Stator on the outside and Rotor on the inside What is a stator Electric motor that turns the rotor at high speed Rotating magnetic field when energized What does the rotor do Spins the anode allowing heat to be spread out across a larger area What do the bearings of the induction motor do Support and enables rotation Define Anode heel effect Variation in x-ray intensity between anode and cathode sides of the tube What side of the x-ray tube has the more intense beam Cathode Why is the beam more intense on the cathode end X-rays produced deeper within the anode must pass through more material which absorbs some of the beam, the absorption reduces intensity on the anode side If the degree of anode angle decreases what will happen to the anode heel effect It increases, a smaller angle means x-rays have to travel through more anode material to exit Define the line focus principle Large Actual focal spot that spreads heat while maintaining a small effective focal spot for better image detail What is larger, the actual focal spot or effective Actual Where is the actual focal spot located On the surface of the anode target Which focal spot goes towards the pt, actual or effective Effective If you decrease anode angle (choose small focal spot) how will that affect the effective focal spot size It also decreases Define off focus radiation Radiation produced outside the actual focal spot which causes blurred edges or ghost images Define tube loading The amount of heat energy generated in the x-ray tube during an exposure, heat units What is the formula for heat units HU= kVp x mA x time (s) x wave form factor What is the average wave form factor 1.4
