Pulse Sequence Design

SpinBenchâ„¢ 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.

Features

  • Multidimensional Bloch simulation with user-selectable parameter axes
  • Real-time updating as parameters change
  • Multiple spin visualization options including 1D graph, 2D image, Fourier transform, and spin vector diagram

  • Relationships between objects are dynamically scriptable using JavaScript
  • Plugin architecture allows easy addition of new features through an Objective-C API
  • Averaging over any number of parameter axes
  • Pulse Manager can generate standard RF and gradient pulses or import from external files
  • Sequence Designer can graphically assemble sequences that vary arbitrarily from TR to TR
  • Pulse anchors allow positioning of gradient and RF pulses relative to one another
  • Support for spin motion
  • Drag-and-drop graphs into other applications
  • Animation mode shows spin progression over time
