Computers and Their Software Programs Are Essential to the Processing
Computers and their software programs are essential to the processing of digital image data for digital x-ray images.This software can compensate for wide variances in radiation exposure to produce an image.Too little or too much exposure is compensated for through _____ to produce consistent image contrast and brightness,regardless of exposure.
C)the 15% rule
The dynamic display of a patient's anatomy using x-radiation is termed
The loss of radiographic image resolution is often referred to as unsharpness.All of the following contribute to total image unsharpness EXCEPT the
A)size and shape of the patient's anatomy.
B)pixel size of the image receptor (IR)and monitor display.
C)size and shape of the exposure field (collimation).
D)image geometry factors such as SID,OID,and focal spot size.
An effective measure of actual exposure compared to a target exposure value is the use of a(n)
B)deviation index (DI).
C)exposure index (EI).
