Weasis is a multipurpose web-based viewer with a highly modular architecture. It has been designed to meet several expectations of clinical information systems and their future evolution regarding medical imaging: providing a web-based access to radiological images, as well as offering multimedia capabilities.

Weasis can be easily interfaced to any PACS supporting WADO via a web portal or as an XDS-I consumer in an IHE (Integrating the Healthcare Enterprise) environment (not yet fully implemented). It has been successfully interfaced to dcm4chee and commercial PACS.
