Pulse Sequence Design
SpinBench™ is a software environment designed for the rapid prototyping and analysis of magnetic resonance imaging experiments. MRI pulse sequences can be easily defined and simulated in a variety of ways, all through a graphical user interface. SpinBench is also useful as a teaching tool for courses covering MRI spin physics.
- Graphical interface
- Growing library of sequences
- Plugin APIs
While most sequences can be implemented without significant coding, additional modules can be added to provide unique capabilities. Sequences can be graphically simulated quickly, reducing development time.
SpinBench™
