Architecture of a web-based DICOM viewer showing segmentations and simulations

In teleradiology doctors view the image data of a healthcare institution from a remote site. To do so they typically connect to an image repository, download the necessary data and finally view it in a locally installed DICOM viewer. Recent research activities in teleradiology [1, 2, 3, 4] focus on the implementation of ubiquitously accessible web-based DICOM viewers which simplify the access and the collaboration among radiologists. However, these solutions either have a weak performance, they run on the client side only, or they are not as feature rich as their desktop counterpart. In this contribution we present an architecture of a web based DICOM viewer which has both, good performance as well as advanced features such as the visualization of anatomical structures. On the client side only native web technologies are used. The whole architecture has been implemented and evaluated in the GoSmart environment, a planning tool for minimally invasive cancer treatment.
