List of image compression rules. First matching rule for a received object uncompressed image defines its compression. Note that you can use this value to Enables to set a compression method based on image typecompression methods dependent on Calling/Called AE Title in the A-Associate RQ from the Storage SCU and on values of particular image attributes (s. Attributes for compression conditions below).

Syntax:
<compression rules> := (<compression rule> <EOL>)+
<compression rule> := [<conditions>] <compression>
<conditions> := '[' <condition> {',' <condition>} ']'
<condition> := <attribute> ['!']'=' <value> {'|' <value>}
<attribute> := 'calling' | 'called' | 'pmi' | 'cuid' | 'imgtype' | 'bodypart'
<compression> := 'NONE' | 'JPLL' | 'JLSL' | 'J2KR'

Supported compression modes:

' | ('JPLY' ['(' <quality> ':' <ratio> ')'])
<quality> := used compression quality between 0.0 and 1.0, 0.75 by default.
<ratio> := estimated compression ratio documented in attribute Lossy Image Compression Ratio (0028,2112), 5.0 by default.

Supported compression modes:

• NONE - do not apply compression.
• JPLL - JPEG Lossless
• JLSL - JPEG-LS Lossless
• J2KR - JPEG 2000 Lossless
• JPLY - JPEG Lossy

Attributes usable to for compression conditions:

• calling - called Calling AE title . Apply the rule to the called AE titles listed as values.in A-Associate RQ from Storage SCU.
• called - called AE title. Apply the rule to the calling AE titles listed as valuesCalled AE title in A-Associate RQ from Storage SCU.
• pmi - photometric interpretation Photometric Interpretation (0028,0004) of image.
• cuid - SOP Class UID . Apply the rule for the SOP Class UIDs listed as values.imgtype - type of image. Apply the rule to the image types listed as values, such as RGB(0008,0016) of image.
• imgtype - Image Type (0008,0008) of image.
• bodypart - Body Part Examined (0018,0015) of image.

The value of the attribute Compression Service#MaxConcurrentCodec also effects the on-the-fly compression and decompression during the store of images by the StoreSCP serviceStorage SCP.

Default Value:

[calling=SAMPLE_SCU1|SAMPLE_SCU2,pmi!=RGB,imgtype!=LOCALIZER]JLSL
NONE
