Abstract/OtherAbstract:
The effectiveness of solid-echo and magic-echo phase-encoding solid-state magnetic resonance imaging methods was tested to determine possible improvement of sensitivity and spatial resolution for investigation of various types of solid polymers. The dipolar interaction refocusing pulse sequences have been used to elongate the possible phase-encoding period and to improve the signal sensitivity. The comparison of both dipolar refocusing techniques with conventional single point imaging method was made. The optimization of the phase-encoding time and magnetization recovery periods were performed basing on (1)H spectra and longitudinal relaxation measurements, respectively. The influence of imaging artifacts (intrinsic for each technique) on image quality was investigated. The effectiveness of the artifacts suppression methods was tested.
