Hi All,
What number should be used for series number(0020,0011) and instance
number(0020,0013)? I am working on a viewer which allows the user to
create structured reports. For each new structured report I create a
new series (a new Series UID) and assign each new report object a
series number of 1 and an instance number of.
In ‘Structured Reporting By David Clunie’ it states series and
instance number should not always be one. What should these numbers
be? Should I count the total number of ‘objects’ in a study and set
the series and instance number based on these counts?
Thanks

Hello KO,
these Numbers are a bit of a legacy, but are still widely used by DICOM
users as quick identification - as DICOM UIDs are hard to memorize.
You may choose whatever you want for these values, but the Series Number
should correspond to the specific Series (identified by the Series
Instance UID) and should be unique inside the Study (identified by the
Study Instance UID) which is containing the series.
Consequently, the Instance Number should correspond to the specific
Instance (identified by the SOP Instance UID) and should be unique
inside the specific Series (identified by the Series Instance UID).
I hope this makes it clearer.
If your application is working on a Study and generates a Series that
should be displayed first, assign the first Series Number to it, e. g.
"1". The Image to be displayed first in the Series (e. g. topmost of the
Image Stack) should be assigned the first Instance Number, e. g. "1".
Then the next Series may be numbered "2" and has also Instances in there
Numbered "1", "2", ... - I hope you get it, please come back to me if
you did not.
Kind regards,
