changing dicom-dict.txt has no effect

5 visualizzazioni (ultimi 30 giorni)
Hi,
I have MR images with a large amount of dicom private tags. I have copied and edited the dicom-dict.txt file to include as the final line
(2005,10A9) UT DistortionCorrection 1
and saved this as dicom-dict-copy.txt, which I had to manually import into the toolbox folder given the permissions on my pc.
I set dicom-dict-copy.txt as the new dictionary using dicomdict('set',filepath)
this is confirmed with dicomdict('get') = 'C:\Program Files\MATLAB\R2021b\toolbox\images\iptformats\dicom-dict-copy.txt'
However, the tag I have set is not recognised when i call inf.DistortionCorrection (inf = dicominfo(image)). Does anyone know why this does not work?

You may refer to the following and try to create a new DICOM tag and write it to a new DICOM image.
After that, the DICOM header in the new image should contains your required information.
filename = 'Original.dcm';
I = dicomread(filename);
header = dicominfo(filename);
header.(dicomlookup('2005', '10A9'))='1';
newname = 'New.dcm';
dicomwrite(I,newname,header,'CreateMode','copy','WritePrivate',true);
new_header = dicominfo(newname);

Brilliant, thanks very much. I am now able to access the information I'm after. I will need to revisit the topic of editing the dicom dictionary though. I'm sure this will be handy in the future.
