Spatial Localization with Single-Sided NMR Sensors

Mobile single-sided NMR

“…44a), and the time-dependent degradation of the sample can be followed (Fig. 44b) [215,242,573,574]. However, in originally homogeneous samples, the aging process may generate layer structures as oxygen diffuses into the sample or if one surface is exposed to UV light (Fig.…”

“…(c) Gradient coil arrangement mounted in the gap of the unilateral MRI magnet of Fig. 7c (left) and slice-selective NMR image of a defect in a textile fibre reinforced rubber tube (right) [76,216,241,242]. The acquisition time for the 50  50 pixel image with a field of view of 4 cm  4 cm was 2 h [241].…”

“…Strain effects in rubber have also been studied by double-quantum NMR (Fig. 21), T 2 instead of T 2eff , and T 1q , as well as by unilateral NMR imaging [242].…”

“…39d). Similar quality images were obtained as cross-sections through a finger [242,494] and the mandibula of a rat head in vitro [478]. But despite CPMG detection and echo addition, the imaging time is still too long for routine use in medicine.…”

Time-Resolved Study of the Photo-Curing Process of Dental Resins with the NMR-MOUSE

“…In the characterization of polymers, unilateral NMR has been successfully used in the investigation of aging and cross-link density as a function of depth in elastomers and polyethylene [21][22][23][24][25]. The profile NMR-MOUSE Ò is made of four parallel magnets in a proper arrangement affirming that the NMR signal is collected from a thin and flat sensitive volume at a fixed distance above the magnet [26,27].…”
