Details in this [publication](http://dx.doi.org/10.1002/mrm.22260) Code can be found in the [repo](https://github.com/mriphysics/water_selective_pulses). The release contains example test data (B0/B1 field maps from 3T PTx system). <a name="ampulse"></a> ## [Amplitude Modulated Multi-band pulses](https://github.com/mriphysics/AM_multiband/#readme) Simple [script](https://github.com/mriphysics/AM_multiband) to compute optimized slice phase offsets for minimum peak amplitude AM only multi-band RF pulses. As presented at [ISMRM 2015](https://kclpure.kcl.ac.uk/portal/files/35847819/mb_AM_submitted.pdf) <img src="images/MB_screenshot.png" width="30%"> <a name="cpmg"></a> ## [Phase Relaxed Localized Excitation pulses for CPMG sequences](https://github.com/mriphysics/phase_relaxed_CPMG_excitation/#readme) <img src="images/square_excitation.jpg" width="60%"> Pulse design method for use with localized excitation in CPMG fast spin echo sequences. Selective violation of the CPMG condition is used as a means for improving background suppression. See [this publication](http://onlinelibrary.wiley.com/doi/10.1002/mrm.25996/abstract) for more details. Code is [here](https://github.com/mriphysics/phase_relaxed_CPMG_excitation/). <a name="reverse"></a> ## [Gradient Impulse Response corrected VERSE](https://github.com/mriphysics/reverse-GIRF/#readme) <img src="images/girf.png" width="50%"> VERSE based pulse design with additional inclusion of gradient impulse response function. See the [readme](https://github.com/mriphysics/reverse-GIRF/#readme) for detailed information.
