Exams larger than media

Hi,

I wonder if there's some work in progress regarding handeling of exams
larger than available medias?

Today, it's quite common that a single CT exam exceeds the 700-800 MB
that can be burned on CD. And a patient may have multiple exams of that
size that makes even a DVD too small.

Is it possible (or has it been considered) according to the standard to
give references to multiple medias (CDs) within the DICOMDIR? (generate
a suite of CDs/DVDs that's referenced from DICOMDIR on disc #1.)

Or is the only clean solution to manually create a number of discs,
each with it's own DICOMDIR? This may be quite time consuming in the
worst case scenario.

Probably not the hottest topic in this group this week, but still
interesting.

Thanks,

Anders

Nothing of this is handled in the standard. The only "clean" solution
would be to create multiple media with separate DICOMDIRs, or to use
a storage medium with larger capacity. DICOM does support DVD-R
and that should be sufficient for a while, unless you start archiving
functional MR studies.

Hi Marco & Anders

You are right Marco.

But when one generates separate CDs with one DICOMDIR on each medium,
and that you have a KOSD/KIN or a SR object on a CD that references
data located on another one, it's not really convenient for the reader
:-)
DVD burning would then be the best solution to handle this.

Have a nice day

Gilles
