Abstract

An integration of SENSitivity Encoding (SENSE) with continuously moving table (CMT) MRI for extended field‐of‐view (FOV) acquisitions is described. In this work, the approach in which receiver coils are attached to the object and move in synchrony with the scanner table is considered. Technical issues dealing with the implementation of SENSE‐CMT are addressed, including coil calibration, correction for non‐uniform magnetic gradients, and specific reconstruction steps. An explanation of combining SENSE with gradient non‐linearity correction is given, as the latter becomes necessary in CMT acquisitions where a large sampling FOV is used. It is hypothesized that SENSE can provide at least a 2‐fold improvement in lateral spatial resolution compared to non‐accelerated CMT acquisitions. The hypothesis is tested in phantoms, where the effectiveness of both SENSE and gradient non‐linearity correction to improve spatial resolution is shown. The SENSE‐CMT technique is further demonstrated in vivo with contrast‐enhanced MR angiography of the peripheral vasculature. Magn Reson Med, 2005. © 2005 Wiley‐Liss, Inc.
