Abstract
Abstract. We report three-dimensional spin noise imaging (SNI) of nuclear spin density from spin noise data acquired by Faraday detection. Our
approach substantially extends and improves the two-dimensional SNI method
for excitation-less magnetic resonance tomography reported earlier
(Müller and Jerschow, 2006).
This proof of principle was achieved by taking advantage of the particular
continuous nature of spin noise acquired in the presence of constant
magnitude magnetic field gradients and recent advances in nuclear spin noise
spectroscopy acquisition as well as novel processing techniques. In this
type of projection–reconstruction-based spin noise imaging the trade-off between signal-to-noise ratio (or image contrast) and resolution can be
adjusted a posteriori during processing of the original time-domain data by iterative image reconstruction in a unique way not possible in conventional
rf-pulse-dependent magnetic resonance imaging (MRI). The 3D SNI is demonstrated as a proof of concept on a commercial 700 MHz high-resolution NMR spectrometer, using a 3D-printed
polymeric phantom immersed in water.
