How to Insert informations into image dcm?

[Thales Castro]

Hi, I have an application in which the use jpg2dcm to convert hundreds of jpg images to dcm. I do it using C and openmp, but now the problem is another: insert informations into image dcm, as patient ID, patient's name, etc ... The idea of create an xml file is good (jpg2dcm -c jpg2dcm.xml image.jpg image.dcm), but I don't know where to start. Would someone give me a suggestion and an example of xml I can use? Thanks!!

There are two methods for creating a new image DICOM.
- Use code source of jpg2dcm is used code java with the tag. (for example in my class Jpgdcm.java) In my class, in syntax following  " dicom.setString(Tag.SpecificCharacterSet, VR.CS, "ISO_IR 100");" creatre a new tag.
- Or using a file xml following  in use my code XmlDcm.java

I'm sorry, Dimitri! My inglish is not very well, maybe I was not clear! I meant tha already can convert jpg images to dcm with command jpg2dcm (https://github.com/dcm4che/dcm4che/tree/master/dcm4che-tool/dcm4che-tool-jpg2dcm), what is missing is to enter the information therein. I believe that with the command "jpg2dcm -c jpg2dcm.xml image.jpg image.dcm" I can, but I don't know how to be this xml file. Or not is possible this way? What I need is of an example of file xml. Sorry if I was unclear!

Hi, fleetwoodfc. Thanks for the help! But I have this error when I run the command ./dcm4che/bin/jpg2dcm -c jpg2dcm.xml input.jpg out.dcm:

I don't know java and I don't have a ideia what can be.

This error come in the name one or several TAGs because the methods forName return hexa of tag.

Yes you will get this error if you use the dcm4che2 tool - use the dcm4che3 version with the jpg2dcm.xml file (the dcm4che2 version uses a .properties file).

Thank you! It worked. :D

I am having same problem. Can you please explain why a .properties file causes this error?
