, A radiographer makes an exposure using an 8:1, 100 line per inch grid. When
processing the image plate (IP) through the reader, the radiographer notices that a
Moire pattern is seen on the displayed image. What is the probable cause of this
artifact?
a. The IP was not fully erased the last time it was used.
b. The IP was upside down in the bucky tray.
c. The grid had a frequency similar to the reader's sampling frequency.
d. Underexposure to the IP.

a. Decrease the milliampere-seconds (mAs) from normal to compensate for
decreased bone density.
