We propose a new method of spatial encoding using a transmit-array system, called TRansmit Array Spatial Encoding (TRASE), that provides a new way of sampling k-space without the need for phase encode gradients. MRI simulations of a standard GE pulse sequence and an equivalent GE-TRASE pulse sequence show nearly identical k-space data and MR image for both methods. TRASE may provide faster data acquisition, reduce acoustic noise, enable shorter TE thus higher SNR, eliminate dB/dt in phase direction and reduce eddy current and motion artifacts. The TRASE method offers many possibilities for novel k-space trajectories.
