Under
Noise on an image indicates that the image was what?
Under exposed
Over exposure increases patient dose and (increases/decreases/no effect) image quality
No effect
When exposing a patient to radiation, it is best practice to follow ____ in order to minimize exposure
ALARA, as low as reasonably allowed
Noise on an under exposed image, can also be called what?
Quantum mottle
___ occurs when the image detector is over saturated with photon energy and data points are not processed onto the final image
Data drop
This helpful tool can ensure that the correct technique is selected based on the size of the body part being imaged
Look up table (LUT) / Exposure technique chart
Quantum mottle (increases, decreases, no effect) image quality
Decreases
This numeric value can be used to ensure that images are in an acceptable range and not over exposed
Exposure indicator (EI) / Deviation index (DI)
____ is a method of decreasing radiation and ensuring that only the area of interest is imaged
Collimation
