You might be interested to see the current list in the IHE Product Registry of devices supporting the REM Profile (essentially DICOM RDSR acquisition, storage, analysis and registry submission).
Currently the number of products there are:
41 total
22 acquisition modality
17 image manager/archive
15 dose information consumer
4 dose information reporter
1 dose registry
For a live report and links to the vendors, products and their IHE Integration Statements, see:
http://product-registry.ihe.net/PR/pr/search.seam?integrationProfile=77&date=ANY%7C1385571268798%7C1385571268798The registry is voluntary, and not necessarily comprehensive, so this may not be all the products that support REM and RDSR.
Perhaps next week at RSNA when touring the Technical Exhibits you can congratulate those vendors whose products have adopted REM and RDSR, and "encourage" those who may not yet have done so.
