Radial xSPEN for Non-Fourier Single-Sided MRI

Motivation: Developing methods for rapidly imaging in an inhomogeneous magnetic field is necessary for the general adoption of single sided MRI, which would bring MR imaging into the doctor's office. Goal(s): We aim to develop a fully spatiotemporal pulse sequence for collecting images with a single sided scanner. Approach: A hyperbolic phase is imparted to the magnetization which results in a time domain signal that is a profile of the phantom. The angle of this profile is rotated to produce an image. Results: Images with no Fourier encoding were produced and the images could be cropped without aliasing. Impact: This novel technique allows for rapid imaging in an inhomgeneous magnetic field. Furthermore, this technique allows for improved resolution because the field of view of the images collected with it can be smaller than the object without aliasing.
