RODRIGUEZ PENA, Alina Dolores  e  SILVA ROJAS, Luis Guillermo. Software Architecture for the Vismedic medical visualization system. RCIM [online]. 2016, vol.8, n.1, pp. 75-86. ISSN 1684-1859.

In recent years, Software Architecture has become a discipline that tries to counter the negative effects that may arise during software development, occupying a significant role in the business strategy of an organization that bases its operations on software. This paper proposes a software architecture based on the integration of the architectural styles: Component-based architecture, Layers based architecture and Pipes and Filters, for the Vismedic medical visualization system, with the objective of reducing the problems of extensibility, reusability and dependencies of the previous architecture. In order to develop the proposal was becoming necessary to study the concepts related to Software Architecture, the architectural features of three established products in the image processing and viewing field, they were: Volume Rendering Engine (Voreen), Visualization Toolkit (VTK) and Insight Toolkit (ITK), and the OSGi specification for component-based development. The proposed architecture integrates the main features of the libraries mentioned above and incorporates the use of plugins to extend its functionalities. The architecture was validated through the Prototyping based evaluation technique and the application of the Architecture Tradeoff Analysis Method (ATAM). The evaluation allowed us to identify the risks of the proposal and to determine that the architecture satisfies the quality attributes defined for this investigation.
