Chapter 3: Radiation Characteristics Flashcards
In dental imagining, what does the word QUALITY used to describe?
Quality= (wavelength and energy)
; The mean energy or penetrating ability of the x-ray beam; controlled by KILOVOLTAGE
Define Voltage
Measurement of force that refers to the potential difference between two electrical charges
Measured in volts (V) or kilovolt (kV)
Define kiloVoltage (kV)
MAXimum voltage, or peak voltage of an alternating current
Define Density
Density is the overall darkness or blackness of an image
Define contrast
Contrast refers to how sharply dark and light areas are differentiated or separated on an image
High kilovoltage and increased density the contrast is ____
low; being able to see many shades of grey
Low kilovoltage and decreased density, the contrast is ____
high; with only LIGHT and DARK areas
