How to extract structures by name Structures by name can be extracted using this code. This code searches for a ROI with the name VOIname. The ROI name is stored in tag (3006,0026). This is of type 2. It must exist but it can remain empty. This code reads all ROI names in the ROI sequence (3006,002...

There are two downloadable reports that deal with the use of SOUPs in medical / critcal software. "Justifying the use of software of uncertain pedigree (SOUP) in safety-related applications" and "Methods for assessing the safety integrity of safety-related software of uncertain pedigree (SOUP)" They...

I can provide a piece of code that reads structures and returns the point coordinates as multidimensional stl::vector, if this would be helpful.

Problem solved.

When using dcmrt together with MeVisLab tests.lib is required.

hello martina,

please indicate which version of the prerelease you are using.
Some details about your project settings would be useful.

If your experience with the dcmtk user community indicates that these simplified sequence items access points are not required or helpful they can be dropped.

In other words, the user of the medium-level API does not need to know about sequences and items or, more generally, about the internal structure of the DICOM information object. In general i agree on that. The full information content is obviously located somehere in the DICOM object. Either as si...

I would rather go one level of abstraction up and define something like getNumberOfExposures() - but of course only for very important elements that are accessed quite often. I think the following approach makes sense: Define access functions to sequence objects like this (example from RTDose): OFL...

The problem is to identify sequence elements accessed frequently. Since most of the sequences are type 3 it is not ...

You are right. DicomImage is powerful and better suited than directly extracting pixel data from the image object and storing it using C-Style arrays as part of DRTImage. Providing image pixel data access by the the DRTImage class will also become obsolete since PixelData access / retrieval is handl...

I will look into dcmimgle. Anything special in mind? I am not familiar with this module.

As we dicussed before the mid-level API will consist of a set of C++ classes that will provide some additional functions that will allow to access data from DICOM RT objects more easily. Each mid-level API class is derived from a RT IOD classs like RT image. class DRTImage : public DRTImageIOD, publ...

Fine, then let's agree on the following: No fatal error messages from dcmrt. No calls to exit or abort from the library. The decision to abort is left to the application that uses dcmrt features. Error messages in case of errors that will not allow an action to complete in a way that the user expect...

Hello Jörg, further debuging reveals that indeed all read methods are called properly. The problem was located in my code. gotoFirstItem() has to be called before entering each of the do loops and subsequent calls to getCurrentItem. It seems that the iterator was not set to a valid item or not initi...
