Guidelines for Optimizing Image Quality
Understanding the cause-and-effect relationship of the parameters applied
during image processing helps you optimize image quality. To produce an
optimum image from the CR System, the proper collimation, positioning,
technique, and the optimum combination of processing parameters are
required.
Performing the Exam
The Image Processing Library (IPL) is an object-oriented library of image
processing algorithms incorporated into the CR System. Each body part and
projection combination produces a unique look for a given image.
When using
Kodak
Flexible Phosphor Screens, the following suggestions will
help you obtain optimum image quality:
• Apply as much collimation as is practically possible on all images.
• Capture only one view per cassette (such as a Posterior Anterior (PA)
hand on one cassette and a Lateral hand on a separate cassette).
• If you must capture more than one view on a cassette, for best quality,
group like views together (such as PA hand and Oblique hand). In this
situation, Kodak recommends that you:
– Minimize the collimation between separate views (such as a thin line
of collimation shown between two views).
– Minimize the exposure overlap between the separate views.
– Use the same bone thickness in each image.
Image Processing
The CR System produces the highest-quality images when:
• The exam, body part, and projection information is accurate and
complete.
• You enter exam information for a cassette rather than default body part
and projection information.
• You make contrast and brightness adjustments only if necessary, before
sending the image across the network.
NOTE: The Image Processing parameters and default settings are
pre-configured. If changes need to be made, contact your Key
Operator.
