7. Portable Media Creators
Demonstration options
Pre-burned CDs (are fast/simple)
Burn on demand
Must write (human-readable) label on CD
Only use content tested during test period
If you burn on demand (modified content), you must change UIDs in images

PDI Technical Considerations

8. “Burn On Demand” – Existing Content
Some Media Creators only take input data and copy to CD.
They do not change information in the data.
They will burn CDs with the same patient ID, patient name and all DICOM UIDs

PDI Technical Considerations

9. “Burn on Demand” – Modified Content
These systems can generate new content (e.g., CT scanner)
They could write attendee name, badge number into the DICOM header
If you do this, you shall issue new DICOM UIDs in these images

Media Creator Tips
Small image sets
How long does an attendee want to wait?
Tailor to some simple clinical example
Include Web option if possible
Choose images with good viewing parameters (window width/level)

Duplicate Disk Issue
Media Readers (all) will see duplicate data throughout the annual meeting
One example is the RSNA CD
You need to have a plan
For example, delete the data after the attendee leaves

21. Useful Option for Media Creators
Send me a CD today with CD content
ftp a zip file to me with CD content
I will test with our test tools
I will post zip file for other participants to test against
Not required but would be a big help
