The meeting was called to order at 09.00 Central Time. The participants introduced

This conference is planned to be held in connection with the University of Pennsylvania
(UPenn) PennApps Fall 2015 Hackathon event. (www.pennapps.org .) This event is held in
The Spring and in the Fall of each year.
Mitt Coats and Jim Gee of UPenn joined WG-27/29 members by web/phone connection with
C. Kahn of U Penn in attendance..
The DICOM members presented to their UPenn colleagues DICOM’s proposal for a
synchronized and integrated program and activities. UPenn representatives described the
Hackathon in detail including the selection of the participating engineering students, the
increasing healthcare content, and the role of the sponsors. This description is well explained
on the pennapps.org web site referenced above.


the DICOM traditional conference presentations. Discussed that the format is
different from the traditional DICOM International Conference formats. It was
decided to name the event:” DICOMweb 2015”
