How to receive DICOM files larger than 2 GB?

[陳信嘉]

I installed dcm4chee-2.18.0-psql successfully and can receive most DICOM files from scanner without problem.

However, large DICOM files (Siemens PET list mode raw data) larger than 2 GB cannot be received by dcm4chee because the "MaximumValueLength" variable under the "jmx-console -> dcm4chee.archive -> Service=StoreScp" has maximal value of 2^32-1 (2147483647, or 2 GB). Other Siemens PET raw data < 2 GB can be received by dcm4chee successfully.

I tried to edit the file "dcm4chee-2.18.0-psql/server/default/conf/xmdesc/dcm4chee-storescp-xmbean.xml" and change the variable type of "MaximumValueLength" from "int" to "long". However, after dcm4chee restarted, storescp failed to receive any DICOM files, and the agent "Service=StoreScp" disappeared in the jmx-console.

Currently I use the storescp under DCMTK, which can receive Siemens PET list mode raw data > 2 GB successfully, but I want to switch to dcm4chee because it has more functions.

How can I extend the "MaximumValueLength" to more than 2 GB in dcm4chee?

I think this is not allowed in dcm4chee as DICOM is limiting that field to 2GB (so it would be against the standard)

Thanks for your reply.

I think I have to transfer those huge raw data in other ways (FTP, SAMBA, NFS...).
