coreMRI

coreMRI simulates MRI experiments by numerically solving the Bloch equations on cloud-based GPU resources to provide high-performance, realistic MRI and quantitative MR (qMR) simulations.

Key Features:

• Cloud-based GPU infrastructure: Executes simulations on scalable cloud instances equipped with GPUs to support high-performance computation.
• Bloch-equation-based simulation framework: Implements a ground-up numerical solution of the Bloch equations consistent with MR physics literature.
• Modular architecture: Employs a modular design that enables integration of the Gadgetron reconstruction framework and a Pulse Sequence Designer.
• Multi-GPU performance and scalability: Has been tested on multi-GPU configurations to reduce execution times for realistic MRI and qMR simulations.
• Pulse sequence and anatomical model integration: Integrates various pulse sequences and anatomical models into the simulation environment.

Scientific Applications:

• Virtual MRI scanner: Functions as a virtual MRI scanner and high-performance engine for advanced MR simulations.
• Simulation-based qMR method development: Supports development and testing of quantitative MR (qMR) methods.
• Pulse sequence and anatomical model design and testing: Enables design and validation of new pulse sequences and anatomical models.

Methodology:

Numerical solution of the Bloch equations; integration of various pulse sequences and anatomical models into the simulation framework; execution and testing on newer-generation GPUs and multi-GPU configurations.
