Abstract
An inverse, current density mapping (CDM) method has been developedfor the design of elliptical cross-section MRI magnets. The method provides arapid prototyping system for unusual magnet designs, as it generates a 3Dcurrent density in response to a set of target field and geometricconstraints. The emphasis of this work is on the investigation of newelliptical coil structures for clinical MRI magnets. The effect of theelliptical aspect ratio on magnet performance is investigated. Viable designsare generated for symmetric, asymmetric and open architecture ellipticalmagnets using the new method. Clinically relevant attributes such as reducedstray field and large homogeneous regions relative to total magnet length areincluded in the design process and investigated in detail. The preliminarymagnet designs have several novel features.
