✦ Synopsis

A modified spiral imaging technique is presented, in which the allowing easier implementation on scanner hardware (8). conventional sinusoidal gradient waveforms are replaced by trape-The current gradient waveform provides the desired reduczoidal ones. In addition to allowing a reduced data acquisition tion in ramping duty cycle, without significant reduction in time, the new waveforms circumvent specific hardware restrictions scan duration or sampling uniformity of k-space. on the minimum scan repetition time.

## Abstract The tradeoff between gradient performance factors, size of the imaging region, and physiological factors such as nerve stimulation typically leads to compromises in gradient design and ultimately suboptimal imaging performance. Local gradient systems can add some performance flexibility

## Abstract Field inhomogeneity and susceptibility variations, coupled with a long readout, can result in image blurring in spiral imaging. Many correction methods based on a priori off‐resonance information, such as an acquired field map, have been proposed in the literature. Automatic off‐resonan

Phase-contrast magnetic resonance imaging (MRI) is used to image particle displacements arising from a 0.515-MHZ focused ultrasound (US) field. The technique used a phase-locked, self-resonant gradient matched to the US frequency in conjunction with a spin-echo sequence to generate phase images of U
