The electronic sharing of medical imaging data is an important element of modern healthcare systems, but current infrastructure for cross-site image transfer depends on trust in third-party intermediaries. In this work, we examine the blockchain concept, which enables parties to establish consensus without relying on a central authority. We develop a framework for cross-domain image sharing that uses a blockchain as a distributed data store to establish a ledger of radiological studies and patient-defined access permissions...

Technology can assist older adults to maintain an active lifestyle. To better understand the effect that technology has on aging perception, we conducted two studies. In the first study, through supraliminal priming, we analyzed the effects of aging- and technology-related stimuli on age estimation. In the second study, we conducted a technological intervention with a group of elders who used four interactive devices and analyzed effects on perceived aging. Results showed that technology-related stimuli did not affect estimated age...

The Danish General Practitioners Database has over more than a decade developed into a large-scale successful information infrastructure supporting medical research in Denmark. Danish general practitioners produce the data, by coding all patient consultations according to a certain set of classifications, on the entire Danish population. However, in the Autumn of 2014, the system was temporarily shut down due to a lawsuit filed by two general practitioners. In this article, we ask why and identify a political struggle concerning authority, control, and autonomy related to a transformation of the fundamental ontology of the information infrastructure...
