FiveTech Software tech support forums

Just to let those few who are interested in DICOM (Digital Imaging and Communications in Medicine) that as time permits I have been making progress with my Harbour based DICOM software. To date I have code that will do the following:

Parse a DICOM file (currently in explicit VR little endian syntax only but adding other syntaxes would be easy)

Send an A-ASSOCIATE-RQ PDU, receive and analyse the returned A-ASSOCIATE-AC PDU or A-ASSOCIATE-RJ PDU, send an A-RELEASE_RQ PDU wait for the returned A_RELEASE-AC PDU and terminate the DICOM Association. Thus you can confirm connectivity with any DICOM compliant device that supports the A-ASSOCIATE service (which pretty much any DICOM device should).

Whilst there is still quite a way to go, progress has been pleasing given that this has had to be very much a part time project.

Happy to share code with anyone who is interested.

Congratulations for your job!! Very interesting.

Hi.
Is it possible to use this for receiving the request of a patients list and sending back the answer
to the RM Dicom machine ?
Thanks a lot.
Massimo.

Hi Massimo, Kleyber

This is part of what is required to do that. All DICOM exchanges over a network start with an A-ASSOCIATE-RQ / A-ASSOCIATE-AC and finish with an A-RELEASE_RQ / A-RELEASE_RP.

To do what you want (and what I want) requires also the bit in the middle - command and data exchange using P-DATA-TF. I am now working towards that. But you can't get to that bit until you have the above working to create the DICOM Association. And I've only just got there. I was quite excited when I got my code working and could set up an association with a remote DICOM workstation over a VPN running across the internet.

I should also add that no matter how capable a particular DICOM implementation is, it can only do those operations that the other DICOM implementation also supports.

Just adding to my previous post. You possibly want to check out what SOP Classes your DICOM device supports. Not sure if you need / want:

1.2.840.10008.5.1.4.1.2.1.1 Patient Root Query/Retrieve - FIND
1.2.840.10008.5.1.4.1.2.1.2 Patient Root Query/Retrieve - MOVE
1.2.840.10008.5.1.4.1.2.1.3 Patient Root Query/Retrieve - GET

1.2.840.10008.5.1.4.32 General Purpose Worklist Management

or some other SOP Class(es)

If you don't have a statement of DICOM conformance my software will shortly be able to ascertain support (but will take longer to actually do).

Hi.
If you make something for receiving a request and sending back a list of patients, please give me a sign.
I can make the tests and buy your program/class.
My customer has just installed an RM machine, with Dicom system integrated.
Thanks a lot.
Massimo.
