DICOM @ OFFIS

Hi, what do the "item.putAndInsertString()" methods return? e.g. do .... OFCondition result; result = item.putAndInsertString(PRV_PrivateElement1, "Some Text"); if (result.bad()) { std::cerr << result.text() << OFendl; } ... You could also try to print the item right after insertion for debugging pu...

Dear Akshaybar Singh,

there is no STOW-RS support in DCMTK right now.

Hi OliWe,

unfortunately I have not really an idea.

Are you maybe accessing a network share in your -xcs executed command that may "hang" every now and then?

Hi,

as promised, I added a few words about UID and (non-)directory processing to the dcmodify documentation. Thanks again.

Hi, no there is no way to do this with a tool from the public DCMTK. There is a commercial tool that is sold by OFFIS and/or ICSMED that is able to convert DICOM multi-frame images to video. It is called dcm2avi . An evaluation version can be requested here . I am not sure whether it works on latest...

Hi, the -if option reads the value from a file, BUT it assumes that the whole file is the new value, i.e the file does not necessarily have to be a DICOM file (or almost never is I guess). So you could create a text file with the desired value of Accession Number inside and use that for -if. This is...

Hi Daniel, 1. Is there a way to read a file really lazy? It seems DcmFileFormat::read and DcmFileFormat::loadFile reads more than just the header. DCMTK automatically does lazy loading in terms of not loading all data (element values) into memory. The decision whether to load an element's value into...

Hi, I don't now std::filebuf, but can't you just do: OFFilename f = ":\\Users\\User\\Documents\\test.txt"; // or simply: OFString f = ... OFCondition cond; cond = dataset.loadFile(f); if (cond.bad()) std::cerr << "Cannot load file " << f << ": " << cond.text() << std::endl; Also your dataset looks k...

Hi, there is no C but a C++ method that does the printing. It is called... print () :-) That's the method that is called by dcmdump (a good place to look for it, right? :idea: ). You can call print() on a DICOM file (DcmFileFormat) or any other class of the DCMTK dcmdata class hierarchy that is used...

Hi, until now I was quite optimistic that the current documentation of dcmodify is clear on that it works on single files. The word directory, recursive, or something that points into that direction is not found at all and all other DCMTK tools directly state if they support directories as an argume...

Hi, dcmodify does not work recursively. You cannot provide directory names as an argument. dcmodify handles every file separately, i.e. it does not care about existing DICOM hierarchies and if you tell it to create a new Series Instance UID (for example), it will do the job separately for each file ...

Hi,

As a general solution use dcmsend instead of storescu.

Hi, Not really a DCMTK question, but.... Ultrasound pixels must not be quadratic but can be rectangular. I guess you already know that after looking at your images ;) This information is stored in DICOM attributes, too. Specifically look for Pixel Aspect Ratio and Pixel Spacing. They are part of the...

Hi Andrew, the DcmItem API that you are using offers calls for nearly all data types like Uint8, Uint32, OFString and so on. However, if the data type (VR) and the respective DCMTK class of the addressed attribute (e.g. Pixel Data) does not offer this call, the method will fail. For Pixel Data, you ...

Hi,

no, right now there is no such class or method.

You could try to extend the existing img2dcm classes, e.g. add a related method to I2DBmpSource used by img2dcm to read from memory instead of a BMP file.

Best regards,
Michael
