I am working on DICOM images in MATLAB. I want to know how to save the changed values of dicom images in MATLAB .I have read the DICOM image and performed the following steps.

dicomread('dcm_image.dcm');

info=dicominfo('dcm_image.dcm');
Value of PatinetName is Usman

info.PatientName

ans =

Usman
Now i have changed the value of PatientName to Khan

info.PatientName='Khan';

info.PatientName

ans =

Khan

Here after this step I want to know how i am going to save my changed values, So that when i >>clear the matlab and run >>dicominfo('dcm_image'); command it should show me the changed value of PatientName which will be Khan.

Regards,

Please use the function dicomwrite to write back the metadata into the image.

C#

image = dicomread('sample.dcm');
info= dicominfo('sample.dcm');
......
//Update info
......
dicomwrite(image, 'sample.dcm', info);
