AMI Medical Imaging (AMI) JavaScript ToolKit for building Web-based 2D/ 3D DICOM apps

AMI Medical Imaging (AMI) Toolkit is a JavaScript toolkit for building medical imaging DICOM-ready apps with 2D/ 3D visualization. It combines a set of JavaScript libraries & Three.JS for WebGL 3D rendering.

AMI Toolkit is featured in our list as one of medical imaging development tools that use WebGL for complex browser-based 3D/ 2D visualization. You can review our list  15 WebGL Medical Visualization Projects.

AMI toolkit is developed by Fetal-Neonatal Neuroimaging Developmental Science Center at Boston Children's Hospital, which has several developers & researchers, They have released several open source medical imaging projects available at their Github.

The project is currently in active development, its adding new set of functions and features on every major release. The developers provided a list of tutorials packed with code samples. AMI toolkit comes With simple one page tutorial at the on how to use AMI, install the requirement Three.JS, & use the package manager/ build system, which is enough for experienced developers.

AMI Viewer

Ami-viewer takes an array of data organized by series/stacks/frames (provided by the Ami-loader and displays it.
