Open BirdcageBuilder

Motivation: Currently the well-known BirdcageBuilder software tool for providing a first prediction of capacitor values for Birdcage Coil design is available only as an app for Android devices. Goal(s): We introduce an Open-source version of BirdcageBuilder available for the MR community to use and improve on GitHub. Approach: From Java code for BirdcageBuilder Mobile, we developed a version in JavaScript. The GUI is an HTML web page, so the webapp runs in any modern web browser on any device. Outputs were validated against the original publication and the Mobile version. Results: The software and code are available to all for use and improvement. Impact: A freely-available open-source version of the BirdcageBuilder software facilitates rapid design of birdcage coils and allows improvement by the MR community. Additional functionalities could include prediction of all resonances of a coil, noncylindrical coils, and output of a CAD model.
