Having trouble getting date and time to get written to .dcm

[johnmann56]

Hello. I would like to know what tags or other factors are necessary for the date, time, patient name, and patient ID to be written to a .dcm file using DCMTK. I have written my own little program using DCMTK to write a DICOM file, which includes statements like

Code: Select all

status = dataset->putAndInsertUint32(DCM_StudyDate,19941016); 

and similar. The .dcm file gets written, and the image is there, but the image info, as viewed in EZDICOM and a couple other vieweres, doesn't have the date, time, etc. I've done a lot of googling looking for a table or other "simple" document which tells what's needed to get these variables to show up in the info, but no luck. Thanks.

As you can read in the documentation you have to use putAndInsertString() for the value representation DA (Date):

Code: Select all

status = dataset->putAndInsertString(DCM_StudyDate,"19941016");

Thank you Jörg, that did the trick. I also had to fix a dumb error in my program which was the REAL problem (emoticon:sheepish).
