Hi,
using the DICOM demo I've been trying to read the columns and rows
in DICOM images to determine the matrix size using the columns and rows in the DICOM header ($0028,$0010) & ($0028,$0011). However I dont seem to be able to display the value.
The code snippet is below
tags:=OriginalImage.IO.Params.DICOM_Tags;
ResolutionLabel.Caption := tags.GetTagString(tags.IndexOf ($0018,$1050) );
Label4.Caption := tags.GetTagString( tags.IndexOf($0028,$0011) );
Label8.Caption := tags.GetTagString( tags.IndexOf($0018,$0080)
); //TR
The ImageEnDialog seems to read & display the value correctly
so I'm not quite sure of the problem.
Thanks,
Adrian

Does this work, Adrian?
var
tags: TIEDICOMTags;
{...}
label1.Caption := String(tags.GetTagString(tags.IndexOf($0010,$0030))); // Date of Birth

Hi,
no unfortunately this does not show anything either (either DOB or columns,rows). The DICOM image (GE MR) does include the information, confirmed with DICOMtools software.
Kind regards,
Adrian |

Must have something to do with the image itself, Adrian. I just tested several DICOMs and have no problem retrieving the values with the code I posted above.
Can you try with a few other files? AFAIK, certain types of DICOM images are not supported, but I have no idea which ones. As I said, my test images work as expected. Maybe you could post a link to some pics as well?

Hi,
I'll try to anonymise some of the key identifier tags and see if I can attach it to a post here.
The strange thing is that the ImageEnDialog does seem to read & display the values correctly when you preview an image.
Thanks,
Adrian |
