Explanation

Question 18 of 18 Question 18 of 18

Using a higher kVp increases heat units (HU)

Select one of the following:

Explanation

( kVp, keV ): the maximum energy available
( keV, kVp ): measure of energy

( step-down, step-up ): if turns in secondary are < turns in primary
( step-up, step-down ): if turns in secondary are > turns in primary

Power loss in copper can be minimized by using ( larger, smaller ) diameter conductor

( N-type material, P-type material ): silicon-arsenic bond
( P-type material, N-type material ): silicon-gallium bond

Types of anodes
( Rotating, Stationary ): Found in general x-ray machines
( Stationary, Rotating ): Found in dental units

As the angle of anode increases, heel effect ( decreases, increases )

Area of the effective focal spot is determined by the angle of the ( anode, cathode )

Thermal capacity of the anode is the amount of heat the anode can ( store, bear ) as opposed to how much it can ( bear, store ) in one exposure
