Hello,
I have to calculate the effective dose after a CT-Investigation.
An Investigation includes several pictures with the same ID.
So I would like to separate the same id’s and count them.
Please help!

    Hi,

    what you need is an aggregation. Use the Aggregate operator, group by id and specify the count of id as aggregation attribute.

    Best regards,
    Marius
