[Insight-users] Dicom Image : How to access to all the tags

[Gomez, Alberto]

Hi,

I have had the same problem but I think that there is no solution. It 
depends on the manufacturer of the US acquisition system, and whether 
the tags are private or not, and the data encrypted. Anyway, if you find 
a solution, I will be very much interested.

Thanks,

Alberto
