Optimizing Image Quality
• Advanced - Includes two parameters:
– Polarity - In general, indicates whether an image is black on a
white background or the reverse. In this case, specifies whether the
Imager will print images with the same polarity as the images sent
from the modality (Positive), or the reverse (Negative).
– Smoothing Type - A value (1 - 15) that specifies a level of
smoothness/sharpness in transition between density differences.
Selecting the Image Quality Parameter Values
Use Table 1 (on page 5-4 ) and Table 2(on page Page 5-8 ) to select the
image quality parameters. The parameter selections are based on modality
type. They also depend on whether the modality is GSDF-compliant. (GSDF
stands for Grayscale Standard Display Function.)
To select the parameters:
• If the modality is not GSDF-compliant, go to “Non-GSDF Modalities”
below.
• If the modality is GSDF-compliant and does not use PLUTs or uses PLUTs
for only some images, go to “GSDF-Compliant Modalities” on page 5-9 .
(PLUT stands for Presentation Look-Up Table.)
• If the modality is GSDF-compliant and uses PLUTs for all images, it is not
necessary to change the image quality values in the Imager. Continue
with
“Setting the Advanced Parameters” on page 4-11 .
Non-GSDF Modalities
Use this procedure to select parameters for modalities that are not GSDF-
Compliant.
Write down the parameter values you select.
1. Refer to Table 1 and find the Modality Type for which the Imager is
being configured.
2. Choose the TFT Set recommended in the table for this type of
modality. If more than one TFT Set is listed, read the Notes in the table
for guidance in selecting the appropriate set.
3. Choose the Table No. (contrast setting) recommended for the chosen
TFT Set. If a number is in boldface type, choose this number first. (You
may have to try more than one Table Number.)
