Stakeholder Workshop. On February 23 2026 a hybrid IPIS Stakeholder Workshop took place with in person site at the Dipartimento di Matematica, Università di Bologna. Six start-ups participated in this workshop:
Bioretics srl
Healthropy srl
Nuvia Health srl
Telemedico srl
Spici srl
Quantum2Pi srl
The technological focus of these start-ups is directly or indirectly related to the field of imaging. The workshop provided an opportunity to present a series of medium-TRL demos (TRL 3 through 5) inspired by computational methods developed within the IPIS project. It also served as a forum for discussion, both to explore possible directions for increasing the TRL of these technologies and to establish potential new collaborations in the context of future PRIN Synergy calls.
