What is a range of shades from black to white with multiple shades of gray
Contrast
characteristic 1:
speed of light
Whats is density?
Its the overall darkness of an image
What is penumbra
blurry areas of an image
What does milliampere (mAs) control?
controls density
What is fewer shades of gray and mainly black/white
high contrast
Characteristic 2:
travels in a straight line
What is low density?
A light image
What is sharpness
how well an image reproduces fine details or distinct outlines of an object
What does milliamperage (mA) control?
controls quantity
What is more shades of gray and mainly gray
low contrast
Characteristic 3:
invisible
What is high density?
It‘s a dark image
What is quality
the energy or penetrating ability of x-ray beam
What does kilovoltage (kv) control?
controls quality
What does it mean when you need to increase kVp
there is too much contrast
Characteristic 4
no mass/ no weight
What is radiolucent?
Dark image and radiation can easily pass through
What is quantity
the number of x-rays produced
What does it mean when you have to decrease kvp
There is too little contrast
Characteristic 5:
absorbed by mass
What is radiopaque?
White or light image and radiation does not easily pass through.
What can be improved by smaller film crystal sizes
sharpness
