  • Examples of the use of Conquest DICOM server

    I just put together a system almost exactly as mikivan did and it works great.


    However just yesterday I noticed the MedDream app will display an incorrect patient name if two studies have the same PatientID. That is, if Patient One has a study with an ID of 111 and then Patient Two has a study sent to Conquest with the same PatientID, both studies will be displayed in the MedDream study list as the "Patient Two" (or whatever the name of the last study sent with that ID). Displaying the studies shows the proper Patient Name in the displayed image but they are incorrect in the Patient List.


    Strangely, doing a query of conquest with a workstation application shows the correct patient names even if they have the same PatientID but they're incorrect using the MedDream interface. I don't know if this is a MedDream issue, a Conquest issue or a MySQL thing. I'm stumped. I'd appreciate any input if anybody has an idea of what might be going on.

  • Use importconverter to append DICOM tag

    Excellent. Thank you Marcel.


    After I posted the question I actually discovered the modality is placing the SeriesInstanceUID in (0008,3010) and am writing that value to (0020,000E) on incoming studies. Fortunately that solved it for this situation.

  • Use importconverter to append DICOM tag

    I have a situation where images coming from a GE C-Arm are seen as one series and are not separated into individual series within a study. These are individual vascular runs (maybe 6 or 10) with each run containing 15-20 images within a study. All images are received but are seen as one series. Conquest forwards these to an iQ-WEBX server that keys into the SeriesInstanceUID (0020,000E) to distinguish one series from another. The header shows the SeriesInstanceUID does not change between each run and that what’s causing this problem. In fact, the SeriesInstanceUID is the same as the StudyInstanceUID.


    I’ve found that the InstanceNumber (0020,0013) is unique to each acquisition within each study and I’ve attempted to add the value of this tag as a suffix to the SeriesInstanceUID using an ImportConverter. While I can replace the SeriesInstanceUID with the InstanceNumber, I haven’t figured out how to simply append the value of this tag as a suffix.


    Are there any ideas on how I could accomplish this?


    Any help would be appreciated.

  • Prefetch previous study by body part

    Hello,


    I have a Conquest Server v 1.4.17c that’s been receiving primarily CR (now DX) studies and routing to two local workstations and an off-site radiologist. It’s been running fine for years with no issues.


    The radiologist is now requesting that when the server receives a Chest exam, that the previous Chest on that patient be autorouted to him as well. This is only required for Chests and not other body parts. The routing to the two local workstations can continue unchanged.


    I’m not sure how prefetch by body part can be accomplished. For instance (in reading the forums) I know it’s possible to prefetch by modality so I imagine it must be possible to prefetch by body part. I’m just not sure how to do it.


    Any help would be appreciated. Thank you.

  • ***Implicit_Parse error

    Hello,


    I have a Conquest Server 1.4.17c that will reject images if a user does any sort of modification to the originally captured image before sending it. Specifically, it's a Carestream CR and if a user forgets to put a lead marker on an image, then electronically modifies the image to put the marker on it, Conquest rejects the image with the following error:


    [CONQUEST] 20170322 07:41:20 ***Implicit_Parse encountered an invalid element length during load of DCM file (in 7fe00010)


    [CONQUEST] 20170322 07:41:20 ***Length = 36723456


    [CONQUEST] 20170322 07:41:20 ***Group Length = 18408844


    ... or sometimes it's the same error but slightly different:


    [CONQUEST] 20170317 13:10:05 ***Implicit_Parse encountered an invalid element length during load of DCM file (in 7fe00010)


    [CONQUEST] 20170317 13:10:05 ***Length = 11744208


    [CONQUEST] 20170317 13:10:05 ***Group Length = 11597612


    I'm not sure what DICOM tag 7fe00010 refers to. Hexadecimal?


    Any help you could provide would be much appreciated.


    Thank you.

  • Delete Patient when no images exist

    I have a situation where a patient is present in the database but no images exist. Using the GUI I get the message "Image File Not Found" but cannot delete the patient by right-clicking and choosing delete. I'm using Conquest v 1.4.17c with dbaseIII.


    Is there a dgate command that I can issue to delete this patient from the database? If so what would be the syntax? Assuming a Patient ID of 1234, would I navigate to the Conquest directory and issue -- deletepatient:1234 in a command prompt?


    Thank you,

  • Modify patient name upon export

    I have a Conquest server running where it forwards all studies to SERVER1 and SERVER2. Everything runs fine except SERVER1 rejects studies when there is an apostrophe in the patient's name (such as O'Neill) probably due to the Access database SERVER1 uses. SERVER2 has no problems with these studies. If I manually add a second apostrophe to the patients name (O''Neill) SERVER1 accepts the study and it is stored properly with only one apostrophe. Of course, Conquest handles these studies fine.


    My need is to have Conquest store studies with apostrophes unchanged and forward the studies to SERVER2 unchanged, but add a second apostrophe only when forwarding these studies to SERVER1.


    I don't think this should be an ImportConverter since I don't want to modify the study Conquest is storing, I only need to modify it under these circumstances to SERVER1 when an apostrophe is encountered. I've been trying to figure out an ExportConverter that can do this but haven't had success. Is this possible?

  • Modify Patient ID from command line

    Hello,


    Looking through the dgate commands in the Conquest manual I see modifypatid:patid,file. Could you give me an example of the syntax for this. Does "file" refer to the path to the study as stored on the hard drive?


    Thank you

  • Destroy Images based on file size

    I have an issue where some studies imported from CD and sent to Conquest have an additional image of only 2 or 3KB. Conquest forwards all received studies to a web server and the web server chokes on these 2 or 3KB sized images. Conquest has no problem storing them but I would like to have Conquest destroy these images and not store or forward them. The images are usually noted as being XR, CR or XA but have no actual image data with them.


    Is it possible to have Conquest destroy images based on their file size?
