Fig. 19. Distribution of different fuel volatility classes acquired from simultaneous two-tracer measurement in an SI engine fueled with multicomponent fuels. For each combination of tracers two single-shot image pairs are shown for each two different detection timings in the intake stroke (60 and 100°ca).

The incremental way an image is acquired in STEM is fundamentally different from the single-shot imaging...

A visualization system with illumination, either synchronized with the drop formatiOTi to produce standing pictures of the drops, or providing single short-time pulses for single-shot images... 

For ultrasonic imaging systems (B-, C- and C-scans) single-shot measurements, fast data recordings, and fast data transfer must be performed. 

Fig. 1.21 Echo Planar Imaging (EPI) pulse sequence. Gradient-echo based multiple echoes are used for fast single-shot 2D imaging. Slice selection along Gs and frequency encoding along C, are utilized. Phase encoding is realized using short blipped gradient pulses along Gp.

For a manufacturer the difficulty is to estimate future developments or trends in NMR microscopy. Based on dedicated laboratory-made hardware developed by the NMR microscopy users and on their requests for new commercial hardware and software, the following topics could become more important micro-coil applications, multiple receiver systems and multi-coil arrangements, NMR microscopy at very high magnetic fields, MAS imaging and localized 1H MAS spectroscopy and localized single-shot 2D spectroscopy. There are no clear-cut distinctions between most of the individual topics, as will be discussed in the following sections.
