but before processing
Question:
What form does some radiation go through the patient
Answer:
absorbed,
scattered, transmitted
,Question:
Image receptor is what kind of devices
Answer:
The device that receives
the energy of the x-ray beam and forms the image of the body part

Scatter radiation ( on a x-ray table) is what
Answer:
A form of secondary
radiation that occurs when an x-ray beam has been deflected from its path by interaction with
matter is called
Question:
Digital systems operate at what speed class?
Answer:
have a much wider
dynamic range (latitude) than film screen systems resulting in fewer retakes

analog information
, Question:
What is a area of unsharpness at each image border due to focal spot source of radiation.i.e. soft
tissues edges around #
Answer:
penumbra

What is caused by movement of the x-ray tube, the pt or IR during exposure-voluntary and
involuntary motion
Answer:
motion unsharpness

If the increase in kVp what happen to attenuation #
Answer:
it is decrease
Question:
What does differential attenuation mean
Answer:
each tissue attenuates
the beam differently or absorb radiation differently

low contrast has many what colors
Answer:
shades of gray instead of
black and white, -long scale
