Dicom Store Speed

Hi


I have developed an application for Dicom Store using LEAD TOOLS V14. I
tested the application with an Ultrasound modality and I found the
Dicom Store working very slow. I then used the LEAD TOOLS Demo EXE to test and it was also working slow.

But when I tried using DCMTK it was three to four times faster than LEAD TOOLS Applicaiton. Can you suggest me on improving the speed.

Thanks in advance

I am assuming you are creating an DICOM Store SCP.  You should
find out what transfer syntax is being proposed and accepted between
the client and the DCMTK.  You then should offer the same and
accept the same transfer syntax with your SCP.  If the image is
compressed and you offer uncompressed as the first option and the
client always accepts the first option, then the client will have to
decompress the image.  This will take time.  Not only in
decompressing, but in transfering (uncompressed images can large) 
If you offer compression as the first option and the client's image is
uncompressed, then compressing the image will take some time.  If
you offer compression and the first option and the client's image is compressed then this will go through quickly.
So check and see what DCMTK is offering and see if you can match this.


Another factor to consider is the packet size of the data being
sent.  You can control the size of each packet using the function
LEADDicomNet.SetMaxLength.  By adjusting the size you can increase or decrease the speed of the transfer.
