Hardware optimized gradient pulses minimize TRs by optimizing gradientshapes so that at least one of the physical gradient axes operates atthe specified limits during dead-times. We demonstrate a method thatreduces the number of waveform shapes required to be designed from~1000 to 12 (i.e. two per encoding gradient pulse per axis) forscanners that can play a linear combination of two pulse shapessimultaneously on each gradient axis. The method provides a simplerimplementation for optimized pulse sequences providing increased SNRefficiency in rapid, interactive imaging and improved frame rates ininterventional real-time imaging.
