Overview:
This 2-hour tutorial is designed to provide an introduction and demonstration of cutting-edge tools for vendor-agnostic sequence development and image reconstruction. To increase statistical power, multi-site studies collect MRI data from different scanners. However, multi-site data cannot be naively pooled together for analysis due to large inter-scanner variability. This variability is due to differences in vendor-specific acquisition sequences, hardware performance, and reconstruction algorithms, thereby contributing to the “reproducibility crisis.” Furthermore, sequence development involves a huge learning curve for new students and researchers alike where they are expected to learn the entire software of a particular vendor.

To address these challenges, Pulseq, VENUS, and gammaStar are three sequence development platforms that have been developed. These platforms provide the building blocks for developing any advanced sequence. The purpose of this tutorial is to demonstrate and educate the MR sequence development community about the immense possibilities offered by these platforms for vendor-independent sequence development and their unique functionalities. Unified image reconstruction will also make the obtained images more reproducible across scanners, along with providing open access to the code. Through examples and open-source tutorial code, the attendees will be able to learn the basics as well as advanced sequence programming on these vendor independent platforms

Target Audience:
Researchers interested in pulse sequence programming and vendor-independent data reconstruction.

As a result of attending this course, participants should be able to:
- Describe the three vendor-agnostic pulse sequence development platforms;
- Describe workflow for vendor-independent and unified data reconstruction pipelines;
- Explain the basic building blocks through concrete programming examples; and
- Explain vendor-agnostic pulse sequence programming using open-source code examples from the presenters.
