Acan.io, Medical Imaging (DICOM) Viewer

Acan.io is a zero-footprint medical image viewer, built on top of OHIF Viewer v3 provided by the Open Health Imaging Foundation (OHIF). It is a configurable and extensible progressive web application with out-of-the-box support for image archives which support DICOMweb.

About

Acan.io, built on top of the OHIF Viewer v3 that is for viewing medical images. It can retrieve and load images from most sources and formats; render sets in 2D, 3D, and reconstructed representations; allows for the manipulation, annotation, and serialization of observations; supports internationalization, OpenID Connect, offline use, hotkeys, and many more features.

Apart from functioning as an individual medical image viewer, the most notable feature is its utilization of Nextcloud, facilitating medical image sharing, collaboration, and security within HIPAA-compliant platform.

Almost everything offers some degree of customization and configuration. If it doesn't support something you need, we accept pull requests and have an ever improving Extension System.

Why Choose Us

Community & Experience

Acan.io is an improved version of the OHIF Viewer v3 that is a collaborative effort that has served as the basis for many active, production, and FDA Cleared medical imaging viewers. It benefits from our extensive community's collective experience, and from the sponsored contributions of individuals, research groups, and commercial organizations.

Built to Adapt

After more than 8-years of integrating with many companies and organizations, The OHIF Viewer has been rebuilt from the ground up to better address the varying workflow and configuration needs of its many users. All of the Viewer's core features are built using it's own extension system. The same extensibility that allows us to offer:

• 2D and 3D medical image viewing
• Multiplanar Reconstruction (MPR)
• Maximum Intensity Project (MIP)
• Whole slide microscopy viewing
• PDF and Dicom Structured Report rendering
• Segmentation rendering as labelmaps and contours
• User Access Control (UAC)
• Context specific toolbar and side panel content
• and many others

Can be leveraged by you to customize the viewer for your workflow, and to add any new functionality you may need (and wish to maintain privately without forking).
