title: Single sided imaging sensor.
abstract: A portable single sided sensor to render depth profiles of MR signal non-invasively is presented. The device utilizes a tailored permanent magnet array producing flat sensitive volumes up to 40 mm from the mobile inspection head. Automated slice selection is performed using a set of switched capacitors in the tuning and receiver circuits. A single channel spectrometer drives the multi-slice acquisition. The RF coil and magnet array geometries have been tailored to house gradient sets to further extend the image rendering capabilities for in-plane spatial resolution (2D and 3D MRI). The probe has been tested acquiring moisture profiles in concrete and porous rocks and measuring diffusion parameters on a phantom sample.
