    Talk Title: Optimizing MRI Encoding Gradients with GrOpt

    Series: Medical Imaging Seminar Series

    Abstract: Gradient waveform design in MRI has traditionally been accomplished with analytical and sometimes ad hoc combinations of trapezoidal gradients. An alternative approach is to use numerical optimization techniques to find the "best" waveform for a set of imaging constraints. This optimization technique has been shown to produce shorter gradients for better scan efficiency, as well as allows for adding constraints to minimize potential imaging errors.

    In this talk we will discuss a range of applications of gradient optimization, including PNS minimization, eddy current minimization in diffusion and flow imaging, acoustic noise reduction, and general scan time improvements. The talk will also discuss and demonstrate the software package designed to generate these waveforms, GrOpt.
