Planar meander-line coils have been proposed as ideal surface coils because they should, theoretically, create highly uniform fields over planes of essentially unlimited area. Experimentally, however, field uniformity of planar meander-line coils is often worse, not better, than even simple loop surface coils. This presentation shows why existing predictions of meander-line coil fields and imaging performance are misinterpreted and how coil geometries can be simply corrected to better match theory. In particular, it is shown how a single extra turn of wire can increase field uniformity by at least an order of magnitude, allowing for uniform, large-area near-surface imaging.
