Cyclone3 project is a platform that enables you to create robust, well integrated and specialized applications of all kinds, not just Web/XHTML based applications.

All applications are based on open standards and technologies, primarily Perl and XUL.

What is a framework ?

Framework is an software infrastructure that is composed of various standard compliant software libraries, programs and utilities which are used in many of our software development projects. This ensures that all project behave according to standards and share the same unified basic structure.

Application framework

Set of standards and libraries which define common behavior and code for applications and enable seamless interaction between them.

Content management framework

CMF is an abstract Application Program Interface (API) which is used for content management purposes.

Multimedia framework

Comprehensive set of libraries, protocols and programs dedicated to sharing of multimedial content over computer networks. These include high quality and intuitive APIs for easy manipulation of many media formats.

Software framework

Software framework is a design concept and an API that is common for a type of software products. For example a third party "billing" system can be supplied by various software vendors but these systems often differ significantly. Software framework ensures that inside our applications they will behave identicaly.

Frameworks are used in every software development process as the interfaces they provide are often well tested and reliable. Also, features such "user management" provided by the framework can be easily customized and used in many projects. This reduces development time and costs.

openDICOM.NET software implements a new approach towards DICOM (Digital Imaging and Communications in Medicine) libraries. DICOM is a worldwide standard in Medical IT and is provided by the National Electrical Manufacturers Assocation (NEMA). This standard specifies the way medical images and meta data like study or patient related data is stored and communicated over different digital medias. Thus, DICOM is a binary protocol and data format.

The openDICOM# Class Libary, main part of the openDICOM.NET project, provides an API to DICOM in C# for Mono and the .NET Framework. It is a completely new implementation of DICOM. In contrast to other similar libraries the intention of this implementation is to provide a clean classification with support of unidirectional DICOM data streaming. Another implemented goal is the support of DICOM as XML. This is not standard conform but very use- and powerful within software development, storage and manipulation. Currently, full read support of DICOM output stream and full write support to XML is supposed to be provided. The entire DICOM content can be accessed as sequence or as tree of class instances. Latter is the default representation of DICOM content by the library.

The openDICOM.NET Utils are a collection of console tools for working with the needed data dictionaries in different data formats (binary and textual), query of ACR-NEMA (prior DICOM standard) and DICOM files and transcoding them into image formats like JPEG and XML files. These utils are written in C# for Mono and the .NET Framework and are using the openDICOM# API for processing.

Last but not least, the openDICOM.NET Navigator recapitulates the openDICOM.NET Utils in form of a GTK# GUI. It provides different views with focus on DICOM data sets and visualization. Connectivity to GIMP is also given for image processing purpose as well as the possibility to run through multi-frame images like a movie.
