Scan Other Folder Contain *.dcm files

  • Images are deleted after import!


    Thanks for your respond

    i have about 10 TB data that seperated to many folders in many PC and i want to migrate all of them

    i use microsoft sql server enterprise edition and i will test the code you mentioned above

    first i will search about how to watch folder and data/incoming and after that i wll test it


  • Hi marcel

    1. I tested it with incoming folder, works fine for me, but its take too long to import data. is there any faster way to import 10TB data?

    2. i dont know why but the images that received from modalities, save as "un" compression.

    how can i compress them as j2 while receiving?

    here is my dicom.ini

  • The current fastest way is to DICOM send the data to conquest, or copy the data and regenerate the database. I have heard that import is slow and plan to fix that.

    Did you restart the server after setting compression? And what is your filenamesyntax?


  • Hi Marcel

    what is the difference between the time that the DB is regenerated and Import Folder?

    I'm sure about killing and restarting the conquest server, maybe I should restart the machine as well !?

    i will send you an image about file syntax



  • Hi,

    the images are already compressed by the sender! So everything works.

    Regenerate does hundreds of images per second. Incoming folder maybe 50 or so. It depends on the database used. What database do you have? You can just run a test server to compare the two approaches. I would be curious too.


  • Hi Marcel

    Thanks for fast response,

    we have two servers and when I compare folders contain MR or CT images in those servers, the size are different !!

    both conquest and pacsplus servers uses jpeg lossless but i dont know why !!

    I dont want to compress incoming folder because they already have

    but the images the receive from MRI and CT-Scan machine must be compressed and archive

    i will send you two images about file syntax from one patient in both server

    hope this help

    i think its my mistake

    i think the other server uses different compression format

    so what is that format?

    jpeg lossy?



    about DB

    I use Microsoft SQL Server Enterprise edition

    so for large data its ok

  • Hi,

    jpeg compression is ON when:

    incomingcompression = J2

    If enable jpeg support is on, and the sender supports it, it will be asked to send compressed, otherwise compression is done by conquesst.

    The compression in is for outgoing connections. Can you post a debug log of the server where compression does not work?


  • Hi,

    Downloaded and deleted attachment for provacy. In dgatesop.lst jpeg support is not on:

    #LittleEndianExplicit 1.2.840.10008.1.2.1 transfer

    #BigEndianExplicit 1.2.840.10008.1.2.2 transfer

    #JPEGBaseLine1 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGExtended2and4 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGExtended3and5 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGSpectralNH6and8 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGSpectralNH7and9 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGFulllNH10and12 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGFulllNH11and13 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGLosslessNH14 1.2.840.10008. transfer LittleEndianExplicit

    #JPEGLosslessNH15 1.2.840.10008. transfer LittleEndianExplicit

    Thus conquest will not recieve in jpeg. However, it should compress after reception:

    IncomingCompression = j2

    It should report:

    [recompress]: recompressed with mode = j2 (strip=1).

    It also tries to compress on forward:

    IQ-WEBX 1234 j2

    As is shown:

    4/28/2020 1:22:41 PM [CONQUEST] ExportConverter0.0: forward C:\dicomserver150\Data\6560050785\1.2.840.113619.2.408.4738430.15465921.19516.1588040467.906.90000_90000_000002_15880639594a34.dcm to IQ-WEBX

    4/28/2020 1:22:41 PM [CONQUEST] Accepted compression: j2

    But is miss:

    [recompress]: recompressed with mode = j2 (strip=1).

    So it remains a mystery why it does not compress. Can you 1) enable debug log and see if something shows up and 2) share an anonymous image?



  • Hi Marcel,

    thanks for deleting the log-file

    according to your post

    1. can conquest received by any of above format?

    2. I will do everything you want and let you know if something happen

    3. I will send you my mri image, no need to anonymous.



    the log shows that compression skipped ---> jpeg compression skipped for < 8 bits data

    do you need the anonymous image?

    Logfile of one MRI patient.txt

  • Ok,

    so that explains the mystery! The images are secondary capture images I assume, can you post one?. Yes conquest can recieve jpeg, jpeg2000, and jpegls. It will recompress it to whatever you set in IncomingCompression. jpegls is nice and fast, but not yet widely implemented. jpeg2000 is slow.
