Re: GSPS or SR ?

What about creating your own sample GSPS objects using e.g. DICOMscope or Weasis.

Re: GSPS or SR ?

Both serve different purposes, so SR will (most probably) never be extended by visual aspects. This is where the GSPS (and its variants for color image, etc.) comes into play: you could, of course, create an SR document (with semantically enriched numeric measurements, coded entries and the like) th...

Re: GSPS or SR ?

The name indicates that this IOD is for referencing monochrome images only. The graphical annotations can also use color.

Re: GSPS or SR ?

The short version of the answer is: if you want to store measurements in a semantic manner, you should use Structured Reporting (SR); if you want to store annotations in a graphical way, you could also use Grayscale Softcopy Presentation States (GSPS). In terms of what is easier to use, e.g. by just...

Re: Sort based on AE Title

Did you already try to use a double backslash, i.e. "\\" instead of "\"?

Re: dcm(j)2pnm not detecting overlay

Maybe, you are right. Currently, it is only documented in the source code. Here is some background information: At the time when I implemented support for overlay rendering (more than 25 years ago), there were many uncertainties in the DICOM standard regarding "color overlays", especially regarding ...

Re: dcm(j)2pnm not detecting overlay

The short answer is: dcmj2pnm does not support rendering of overlay planes in color (e.g. RGB) images. It only works for monochrome DICOM images.

Re: Stop displaying conversion info in logs.

If you don't want to disable the debug and trace logger of the dcmdata module completely, it would probably be the best approach to introduce a new (sub-)logger (e.g. "dcmtk.dcmdata.protected") for the information concerned. You could then disable (or redirect) only this logger. Maybe, this approach...

Re: Carestream Trophy Panoramic images too bright

Since there are no VOI LUT settings in the DICOM data set, it is up to the viewer (rendering tool) to select appropriate settings. The tool dcmj2pnm provides the following options for this purpose: VOI LUT transformation: -W --no-windowing no VOI windowing (default) +Wi --use-window [n]umber: intege...

Re: movescu.exe: cannot redirect output to log file

In more recent DCMTK versions, the stderr stream is no longer merged with stdout (on Windows systems). That means, if you want to redirect stderr to a file you could e.g. use "2> logfile.txt" or "2>&1 logfile.txt".
Alternatively, you could use an appropriate logger configuration.

Re: Invalid sop instance uid - bad Dicom file

Leading zeros ("0") are also not allowed, e.g. in ".06.09.". See UID Encoding Rules in DICOM PS3.5.
