When lower kilovoltage settings are used.. - A high-contrast image will result.
An image with "high" contrast - Has many black areas, many white areas, and few
shaded of gray.
With higher kilovoltage settings.. - Low contrast results.
An image with "low" contrast - has many shades of gray instead of areas that are
predominantly black and white.
High Contrast - Short Scale
Low Contrast - Long Scale
Exposure Time - refers to the interval of time during which x-rays are produced.
Impulse - is a term of measurement that refers to the fact that x-ray are created in series
of bursts or pulses rather than in a continuous stream.
Quanity - of the x-ray beam refers to the number of x-ray produced in the dental x-ray
unit.
Amperage - Determines the amount of electrons passing through the cathode filament.
Ampere - Is the unit of measure used to describe number of electrons, or current flowing
through the cathode filament
Milliampere - Is equal to 1/1000 of an ampere.
Milliamperage - Regulates the temperature of the cathode filament.
Quanity - Milliamperage
Intensity - Is define as the product of the quantity and quality per unit of time of
exposure.
Target-surface distance - The distance from the source of radiation to the patient's skin.
Target-object distance - The distance from the source of radiation to the tooth.
Target-receptor distance - The distance from the source of radiation to the receptor
The quality of the x-ray beam is controlled by - Kilovoltage
