Open source/ Libre software are becoming a major part of daily usage for many users world wide, Medical/ Healthcare sector is no exception. For DICOM Viewers we have many open source Desktop clients some of them are enterprise-grade Viewers. Most of the desktop open source DICOM viewers come with platform restriction, hardware requirements, and some demand specific configuration to work. However, Web-based DICOM viewers on the other hand only requires a modern web browser as a client.

We have published here a list of Free Online Web-based/ Cloud DICOM viewers, However, we complied a list of Open source Web/ Browser-based DICOM viewers, aiming to provide some insights for developers and software engineers so as decision makers.

We have covered several DICOM viewers categories:
