Compression using Linux

  • Hello, I just started to try Conquest with Linux (specifically Scientific Linux 6) I have it running and it seems to be working. I would like to change the compression incoming to store as j6. I entered and saved j6 in the dicom ini and restated the server. As I send images in, I do not see that it saves the images as compressed. How do I know for sure if they are being stored as JPEG lossless?

  • I am using conquestlinux1416beta. My Dicom.ini is pasted below. We are going to use this server as a offsite backup of our PACS system image database for disaster backup. That is why I was planning to use j6 to maximize storage. We use a windows server now, but would like to convert to Linux.


    We have dgate set to start at boot. Btw...How to I view the server status messages with when the server is already running?
