DCMTK validation question.

Hi

We would like to use the DCMTK lib and need to give a list of CT systems that it was validated with. Is there a list of such CT systems?
In addition, if there was phantoms which had used for DCMTK validation , is it possible to share their images?

Thanks
Audi

OK. I found it.
The reason was that the dicom data was jpeg compressed,
This can be known by checking tag 0002,0010 which its information inform about the data type

And then, in order to be able to read, there is need to decompress the data.

and then we can read it as usual

FYI

Maybe i had a differend problem but I solved using: OFString slice_location; OFCondition status = file_format.getDataset()->findAndGetOFString( DCM_SliceLocation, slice_location ); double double_slice_location = atof( slice_location.c_str() ); I applied that to each .dcm file and then sorted them. ...

How to know the order of dcm images

Hi all

I'm new to the world of DICOM. I noticed that the order of the pictures (in order to set a volume), is not by the name index. I would like to load them into memory and order them in correct way so I will have the correct volume memory. How can I know the order ?

Thanks
Audi
