Maintaining Image Quality
Data Histogram No. 1
This histogram’s position on the LUT shows that no image was captured.
Raw Data Histogram No. 2
This histogram’s position on the LUT shows that an image was captured.
Image is all white or all black
• Confirm an image was captured on the plate.
• Remove black surround.
Printed image has stripes
through it
• Check laser printer for errors; find out if problem is restricted to one or
for all prints produced on that particular printer.
• Check clinical and diagnostic workstations to see if the same problems
occur when viewing the distributed image.
• Have your Key Operator print SMPTE test pattern from the Key Operator
Functions , System Configuration , Next , and Next screen. If stripes
exist on the test, it may be a printer issue. If stripes do not exist, there is an
issue on the CR System or the monitor. Contact the Applications Consultant.
No Image
• Confirm that an image was captured on the phosphor screen using one of
the following methods:
1.
Change the tonescale to Raw Data and turn off Edge Enhancement,
Black Surround Mask, EVP, and Grid Suppression. If there is no
visible image, nothing was captured on the phosphor screen.
2.
View the histogram. If the histogram is outside of the LUT curve on
both the processed and raw data, no image was captured.
• If the image was captured, adjust the contrast and brightness to produce
an acceptable image. See “Adjusting Contrast and Brightness” on page 6-2 .
