DICOM @ OFFIS

Dear all, I have a problem which seems to be related to sequence encoding. In a Modality Worklist SCP, I build datasets "from scratch" i.e. by adding tags (from database records) to an empty dataset which at the end makes up one worklist response dataset. If the dataset contains sequences ...

When you call the method DcmFileFormat::loadFile() which data is loaded? The pixel data, the tags, both or none of them? Tags with a length that does not exceed DCM_MaxReadLength (defined in dcobject.h) which is 4096 by default, are loaded into memory. For all other tags, the location within the fi...

Marco,

thanks for your reply. I will try that.

Dear dcmtk experts, is there any way to preserve an undefined sequence-length encoding when transferring images from storescu to storescp? It seems that sequences are always being stored to disk with calculated explicit sequence lengths. When I transfer a dataset having private tags with VR=SQ and u...

If the image is compressed, you must convert the Transfersyntax. dcmdjpeg will do the trick. If the image is a grayscale image, it is impossible to set a "red pixel in the center", unless you convert the image to RGB which would affect more tags than just DCM_Pixeldata (e.g. BitsAllocated,...

Hi Kmilo,

your problem is not related to the compiler (#include) but to your linker. You have to link dcmimage, dcmimgle, ofstd and dcmdata and if you use JPEG compression, you also have to link the libjpgXX-libraries.

Dear DCMTK experts, I have found a problem when processing an association request. Under certain circumstances which seem to be hard to reproduce, a TCP connection is established but no data has been received yet. Then ASC_receiveAssociation returns EC_Normal, but actually no association request has...

You will have to write a little program for that. DcmDataset is the class that you need. Have a look at the source code of dcmdjpeg and you will see that a few calls are used to convert the transfer syntax.

The name of the method might be confusing. createWindowsDIB does not create a BITMAPINFO header structure. It just renders the DICOM image to a buffer that can be referenced from a BITMAPINFO. In other words: Just the raw buffer is created. You have to build the BITMAPINFO structure yourself.

Probably the easiest way to transfer all the images would be a file copy/move. AFAIK, eFilm stores the Images as DICOM Part 10 files to a configurable path.

Where do I get the StudyInstanceUID (0020,000d) from? You have to issue a StudyInstanceUID that is generated in your (RIS?)-application What do the Scheduled...tags (0040,....) exactly mean? This is defined in Table C.4.10 DICOM Part 3 What is the difference between RequestedProcedureDescription (0...

There are sample worklist files in dcmwlm/wlistdb. They can be converted to binary DICOM files with the dump2dcm-tool

Hi,

You have to add the called AETs (in your case "dale2") to the AETable

youir building procedure just looks fine, but to know, where this (serious) error comes from, you would need to debug dcmqrscp, meaning running it in a Visual Studio Debug Session and then executing line per line. This would give us information, where to fix this problem. ...or alternatively, set a...
