Enhancing the Open Health Imaging Foundation Web Medical Imaging Framework
To develop training materials, perform software maintenance, expand outreach, and provide community support for the Open Health Imaging Foundation (OHIF) web-based medical imaging framework including its underlying libraries (e.g., Cornerstone).
The OHIF Viewer is an extensible web viewer framework for medical imaging. It offers a professionally-designed user interface that makes it easy to operate by end users, and provides basic image review functionality (e.g. image manipulation and measurement) as well as advanced visualization (e.g. multiplanar reformatting). It is written as a client-only, single-page web application which can easily be embedded into third-party applications or hosted as a standalone website. The platform provides extension points for software developers to include custom tools or visualizations and adapt the system for their workflows. It is standards compliant and relies on DICOMweb for data exchange and OpenID Connect for authentication, but can be configured to use alternatives. Additionally, the user interface (UI) components are provided in a standalone library so that developers can create custom extensions. Extensions have been built to provide support for 3D image segmentation, radiation therapy image annotations, and visualization of whole-slide microscopy images using Google Maps-style tiling (i.e. digital pathology). The core business logic, as well as community-contributed internationalization files for the UI components, can be used independently through separate NPM packages. OHIF relies on Cornerstone by default for DICOM image retrieval, decoding, rendering, and interactive tool support.
