Area of Science:

  • Medical Imaging
  • Software Engineering

Background:

  • Developing magnetic resonance imaging (MRI) applications requires complex pulse sequence programming.
  • Existing text-based tools can have a steep learning curve.

Purpose of the Study:

  • To introduce a novel graphical pulse sequence programming tool for MRI applications.
  • To enhance the ease of use, flexibility, and hardware independence in MRI software development.

Main Methods:

  • A three-module system was developed: a graphical sequence editor, parameter management, and a sequence compiler.
  • The tool utilizes a two-step compilation strategy for hardware independence.
  • Graphic elements are combined with text expressions for enhanced flexibility.

Main Results:
