Selective excitation using Multix and Active contouR Technique

Selective excitation using Multix and Active contouR Technique (SMART) proposed here, is an optimization framework for the joint design of k-space trajectories and radio frequency pulses. The combination of active contour and the multix has been done for the first time which allows the use of arbitrary k-space trajectories. SMART has been prospectively implemented on two channel 3T Philips Ingenia system for different geometric shapes and organs to demonstrate arbitrary volume selective excitation and has shown improved excitation profile. Current and future work involves implementation on in-vivo studies.
