A technique has been developed, based on a planar B0-coil, to reduce artefacts in MRI caused by respiratory motion in patients. This should enable sub-millimetre resolution images to be detected using a MEMS microcoil. The microcoil, subject of a separate publication, was developed for catheter mounting and deployed in an endoscope for MR imaging of cholangiocarcinomas. The B0-coil has been designed to generate 1 mT, parallel to the main field of MRI scanner, with 80 Apk and to be homogenous to within 1% in a 150 mm DSV.
