Hi Mr. Ramon,
I'm also with patients problems :-(
So far I discovered that these problems have to do with the StorageScp service, in particular with the attribute "PatientMaching". This rule indicates how to use the demographic information:
pid,issuer?,[familyname,givenname,middlename?,birthdate]
The info about this attribute is a bit complicated for me, but the important thing is that a fied with '?' mark implies that a missing value on this attribute in the received DICOM objects wil match with any existing value in existing patient records.
Maybe you could try removing some demographic fields or use the '?' mark .
I'm sorry I cant help you any further in this matter.
If you get more information maybe you could help me ;-))
Regards
