The development of a low-cost portable MRI scanner for brain imaging could facilitate imaging in new sites with insufficient space, power, or funding for traditional scanners. To address this need, we previously established a 3D encoding method using a rotating inhomogeneous B0 field and RF phase gradients, but uncontrolled field patterns showed encoding problems near the object center. Here we show this problem can be fixed in an optimized 122 kg head-sized permanent magnet with a built-in approximately linear encoding field in 2D images with improved resolution homogeneity across the field of view.
