Dear lpugliese
K-PACS does only provide very limited support for transfer syntaxes. To import and store JPEG lossless data you need to do the following:
1. For import via DICOM: Open the Server Admin Tool. Stop the K-PACS server. In section "Dicom configuration" activate the setting "Prefer JPeg lossless". As additional parameter set "-nd". Afterwards restart the server. Now you can send images with transfer syntax JPEG lossless to K-PACS and they will be stored that way.
2. For import via Filesystem: Close K-PACS, open the k-pacs.ini and set the parameter "NoTSConvertionOnImport=" from default value "0" to value "1". Save the settings and restart K-PACS. All images will now be stored with the same transfer syntax that they already have. There is no option, though, to change the TS during import.
WARNING: K-PACS will not always be able to display compressed images in the viewer. The display may be corrupted or no images may be displayed at all. To ensure a correct image display, use the default setting for decompression.
For a much enhanced handling of the different transfer syntaxes in both communication and display as well as lots of further useful features, please use our professional software, the radiological reading station iQ-VIEW.
