Computing - How to transfer images from the GE 1.5T scanner

Structural images

  1. In the upper left hand corner of the scanner screen is a window containing several icons. Jump to the exam browser desktop by clicking the icon that shows a computer and filing cabinet connected by a cable.
  2. From the exam browser menu, choose "Network -> Select(ed) remote host". Then select the server you want to send your data to (e.g. boomerang).
  3. With your exam selected, choose "Network -> Send examination".
  4. In the status area (lower right-hand corner of the icon window), you should see a message that says "Sending...". When the transfer is complete, the status message becomes "Sent...".
  5. (Optional) To see the status of all the scanner's network transfers, choose "Queue -> Network" from the menu. If your job is listed as "Active", then it is currently being transferred.
  6. If you transfered your images to boomerang, it should become available on the IRC Calendar within an hour.
  7. Troubleshooting: to test the network connection, use "Network -> Ping DICOM host". You should see a message about the host being alive. You can also try sending a single image ("Network -> Send image" in the menu). A "Sent" status message should quickly appear. If the transfer doesn't seem to be working, please contact the receiving server's administrator (Scott Martin for the IRC Linux servers).

Functional images (P-files)

  1. In the upper left hand corner of the scanner screen is a window containing several icons. Jump to the tools desktop by clicking the icon that contains pictures of tools.
  2. In the lower left of the desktop is a window entitled "Services Desktop Manager". Open a command-line window by clicking the "C Shell" button at the bottom of this window.
  3. In the command-line window, change to the "/usr/g/mrraw" directory by entering this command:
    cd /usr/g/mrraw
  4. Type "ls -l" to locate your P-files. Use the timestamps to determine which one was produced first.
  5. Now transfer the P-files by typing in something like this:
    transfer_pfiles P12345.7 my_account boomerang
    In this example, P12345.7 is the first P-file you identified in the previous step. Replace my_account and boomerang with your username and server, respectively. You will be asked for a password and then the transfer will begin.
  6. Once the P-files have been successfully sent, you will need to log into the server. You should see the P-files in your home directory. Move them to the appropriate subject directory on your server.
  7. Reconstruct the P-files. (IRC Linux servers only)
    The easiest way to do this is with the "recon_epi" command. To reconstruct a single P-file, type something like
    recon_epi P12345.7
    This will reconstruct the P-file and place the resulting Analyze images into a directory called "12345_func_an". If a directory with this name already exists, the program will give an error message and stop.
    To reconstruct all of the P-files at once, type this:
    recon_epi P*
    Several directories will be created, one for each P-file.
