Abstract
An improved imaging technique and apparatus for direct temporal encoding of spatial information of an object is presented. The signal collected from the object after application of excitation energy in a magnetic field is directly representative of the spatial position of the object without the need for the signal to undergo mathematical transformation. This is a result of the excitation scheme that generates transverse magnetization across the field of view that is a function of X (read-out) and Z (slice select) positions, resulting in a two-dimensional phase profile that, upon application of a constant gradient along the Z axis, elicits a signal that is directly attributable to the spatial position along the read-out dimension without application of mathematical transformation.
