22. send retrieve Can we do anything else? • Yes! • If we can retrieve (pull) data back to the Odyssey, could we use the Dicom server as an Archive??

23. To Retrieve Data • Program Conquest with Odyssey Information • Program Odyssey to Import

24. To Retrieve Data • On the Odyssey, Get the images from Conquest

25. Pre Dicom Post Dicom Comparison • Compare image, counts, pixel size, etc, etc • No Difference

26. 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?

27. 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 backing-up/archiving of data, which is handy for long term storage
