A big data approach to explore medical imaging repositories based on DICOM
Santos, Milton; Rocha, Nelson PachecoMedical imaging repositories based on the DICOM format such as Picture Archiving and Communication Systems have a huge potential from a big data perspective. The study reported by this paper aimed to verify on how the big data lifecycle processes, from production to consumption might be implemented to take advantage of the DICOM standard and respective data sources. After identifying the different processes (i....
Applying the nominal group technique for the conceptual validation of ehealth s...
Rosa, Ana Filipa; Martins, Ana Isabel; Cerqueira, Margarida; Santos, Milton; Silva, Anabela G.; Rocha, Nelson PachecoThe development of ehealth applications is a complex task, not only in technological terms, but also in the understanding of both the users' needs, expectations and contexts, and the business models. Therefore, initial conceptual validations might be essential to verify whether the proposed solutions are adequate, sustainable, and worth to be developed. The study reported by this paper applied the nominal group...
