acquisition is known as _____
postprocessing -
Adjustments made after acquisition corrections have been made, targeted as refinement of
the image is known as _____
segmentation -

histogram -
A graph plotting the pixel count for each brightness level (density) within an entire image is
known as a _____

reference histogram -
For each radiographic projection, computer memory includes preset _____ _____ for an
