Gray Scale expansion Enhancing visibility of detail Gray scale compression
In digital image technology, once the image data is sent to PACS..
the data is fixed and not able to be reprocessed
When using a Fuji CR system in the fixed mode of operation
The system will not correct for exposure inadequacies and adjust for density problems Your exposure techniques must be accurate, similar to film/screen technology
In digital image processing, the digital data set is arranged into a histograph distribution in order to determine the
Exposure index Values of interest (VOI)
The purpose of a LUT is to
Apply a predetermined scale of contrast to the digital data set
If a radiographer applied an extremity LUT to a low contrast area like an abdomen radiograph data set, the image would demonstrate
FActors associated with Moire effect are
It results from a conflict in spatial frequencies between the grid frequency and laser scanning frequency. It produces useless diagonal dark lines across the finished image. It is eliminated with ultra-high grid frequencies 178-200 lpi.
A common feature between indirect and direct DR technology is
