Mtrk-A flexible environment for developing open-source MRI pulse sequences.

ABSTRACT:

Purpose

To introduce mtrk, a new open-source tool based on modern software-engineering principles that simplifies pulse-sequence design, implementation, and dissemination.

Methods

The mtrk framework is vendor-agnostic and relies on a compact and human-readable descriptive language. Users can design pulse sequences using either a Python-based programming interface or an intuitive graphical interface. The graphical interface also allows for visualizing pulse-sequence diagrams. A driver sequence was developed to run mtrk sequences on MR scanners. A spin-echo sequence was designed with mtrk and converted to Pulseq for comparison. Both versions were compared to an equivalent vendor sequence in phantom and in vivo experiments.

Results
