Determine if images can be compressed by checking the following tags in the DICOM header information of the image:
overlay_bits_allocatedbits_allocatedphotometric_interpretationbits_stored
To check the tags, use Client Image area tools or the CLUI utility.
 | Note: You can also search the impax.log file for the study_ref value. On Solaris, to find the location of the study, type /usr/mvf/bin/show-study-image-paths -an accession_ number |
To determine if images can be compressed (IMPAX Client)
In IMPAX Client, click Service Window
,
then click the image.or
Ctrl + right-click the image, then select Information > Service Window.
In the Service Window, search the list for the appropriate tags.
To determine whether images can be compressed, compare the tag values to the tag values table.
To determine if images can be compressed (command line)
In CLUI, type
go util
select study_ref from dosr_study where accession_number='accession_number'
where accession_number is the unique alphanumeric study identifier.
Type find study study_ref
where study_ref is the result from the select command.
Copy the study location provided.
To exit CLUI, type exit.
At the command prompt or terminal window, type ddo_print -f file_name location.dcm
where file_name is the name of the file to write the output to and location is the result of the find study command.
On Windows, at the command prompt, type grep -e bit -e interp file_name.
On Solaris, at the terminal window, type /usr/xpg4/bin grep -e bit -e interp file_name
where file_name is the name of the file you wrote the output to.
To determine if images can be compressed, compare the tag values to the tag values table.
