This chapter discusses the concept of open-source picture archiving and communication systems (i.e. PACS), which are low cost, and easy to re-configure and to customize for the specific user needs. Opensource PACS are based on relatively low cost computational resources, and are built by integrating opensource software components that implement basic services of a PACS. These services are described in this chapter, as well as how to integrate them. As an illustration, a PACS based on open-source software components for angiographic studies is discussed. Using the open-source approach, we expect to help diffusing the PACS technology by reducing its development and maintenance costs by using components easily available (e.g. desktop PCs).

Open Source Development

This paper presents an empirical analysis of the Open Source development process from the point of view of the involvement of the developers in the production process. The study focuses on how developers contribute to projects in terms of involvement, size and kind of their contribution. Data have been collected from 53 Open Source projects and target application domains include different areas: web and application servers, databases, operating systems, and window managers. Collected data include the number of developers, patterns of code modifications, and evolution over the time of size and complexity. The results of this study show evidence that there are recurrent patterns in Open Source software development and these patterns are common to all the projects considered even if there are no superimposed processes for development, application domains are different, and there are contributions from people spread across the world.
