Abstract

The aim of this thesis is to introduce a web-based and open source DICOM viewer. Web technologies have already been successfully used in medical informatics. Since software used for medical applications is commonly proprietary and mostly restricted to certain operation systems, the combination of web technologies together with the DICOM standard is a natural next step. For this reason, this Bachelor's Thesis attempts to lay the basis for such an open source project. Digital Imaging and Communication in Medicine (DICOM) is an established and nonproprietary standard for the storage and the exchange of information in medical imaging. DICOM defines not only a data format, but it specifies also a network protocol based on the ISO/OSI-model. This work provides first an overview of the DICOM's history and describes its main concepts. Health Level 7 (HL7) is an industry standard for the data exchange between different hospital information systems. Integrating the Healthcare Enterprise (IHE) is an initiative that aims to harmonize the exchange of data between information systems in health by promoting common standards such as DICOM and HL7. Based on a clinical workflow, the interaction of DICOM and HL7 by using IHE is shown. The DICOM Web Viewer was designed as a "Rich Internet Application" and developed in JavaScript, HTML5 and CSS3. To create an easy to use user interface, state-of-the-art DICOM viewers were investigated and a common set of features were identified. DICOM files are parsed directly in the browser using JavaScript and then visualized using the HTML5 element. In the appendix the source code is described in detail and all third-party libraries get listed. The implementation shows, that web technologies are well suited to view DICOM images in a web browser. Especially its cross-platform usability makes the DICOM Web Viewer even more promising for the future and may replace traditional proprietary software.
