The invention describes an ultrasound pulse echo sensor, in the case of which, if static targets are present, the sensitivity of the sensor is reduced at exactly the relevant point on the time axis without the overall sensitivity being adversely affected. The invention in this case makes use ...
Ultrasound imaging Charles A. Sennoga, in Bioengineering Innovative Solutions for Cancer, 2020 2.5 The pulse-echo principle Although continuous waves are generated and used most commonly in basic US fetal heart monitors, the majority of US diagnostic systems employ pulse waves. Here, waves are gener...

determining a reference point of the leading body to be defined for the ultrasound inspection of the workpiece, for example an edge of the leading body, by the latter being disposed, for example, flush with the edge of a testing body and the back-face echo of this testing body being ...
d, Principle of XUV pulse shaping at the FEL FERMI. Intense seed laser pulses overlap spatially and temporally with the relativistic electron bunch in the modulator section of the FEL, leading to a modulation in the electron phase space. The induced energy modulations are converted into electron-...
