Introduction
• Conducting a multi-centre trial
• Needed to share/send patient images via email
• Other centres did not have Philips cameras (tut tut!)
• So share images using Interfile
• But….. Interfile images were cobbled! (another story!)
• Have a go at sending images in Dicom format instead
• How do we do that?
• And what is Dicom?
What is Dicom???
• Digital Imaging & Communications in Medicine
• Standard image file format created by NEMA
A Hypothetical Dicom File
Patient info (name, DOB, sex)
The Header
Image info (number of images)
(Lots of text that
describes the image)
Study info (scan date, institution)
The Image
What is Dicom???
• Digital Imaging and Communications in
Medicine
• Standard image file format created by NEMA
• Aims to aid the distribution and viewing of
medical images (e.g. CT scans, MRIs, and
ultrasound)
So How do I convert Odyssey
Images to Dicom?
Read the Manual!
Asking Philips Engineers
Ask around!
• Cannot simply create a Dicom file
• Have to send Dicom images to a Dicom Server…..
• What’s a Dicom Server…..???
What’s a Dicom Server ?
• It’s a networked PC running a ‘program’ that will accept
Dicom images.

Summary
Installed Conquest Dicom Server
Name: conquestsrv1
Number: 5678
IP address: 192.168.4.147
Told the Odyssey about the
Conquest Dicom Server
Name: conquestsrv1
Number: 5678
What PC it sit on (IP address)
It works!
Odyssey
My PC
Can we do anything else?
• Yes!
send
retrieve
• If we can retrieve (pull) data back to the Odyssey,
could we use the Dicom server as an Archive??
To Retrieve Data
• Program Conquest with Odyssey Information
• Program Odyssey to Import
To Retrieve Data
• On the Odyssey, Get the images from Conquest
Comparison
• Compare image, counts, pixel size, etc, etc
Pre Dicom
• No Difference
Post Dicom
Further Work
• Do other types of images retrieve OK?
• Do we need more than one server on a PC?
• Can we put the Dicom Server in a remote ‘off site’
position e.g in the IT department?
• Can we set Odyssey to
automatically archive data?
• Is there better server software
available?
Conclusions
• Setup a FREE Dicom server in our department
• It works!
• Have the ability to convert Patient images to Dicom,
enabling us to share data with other centres.
• Given the department another option for backingup/archiving of data, which is handy for long term
storage
