Numerical and Experimental Study of Pacemaker Safety under MRI
… issue of pacemaker/defibrillator with MRI RF (radio frequency) coil and human body model, novel techniques for the evaluation of MRI-induced heating or induced voltage in the vicinity of implanted metallic lead have been developed based on the reciprocity theorem. The measurement configurations …

Biomedizinische Anwendungen der NMR-MOUSE
… magnetic field is generated above the probe. A radio-frequency coil is placed in the gap between the magnets for excitation and reception of the NMR signal. The tissue sample is either directly placed on top of the probe surface, or the NMR-MOUSE is fixed to a freely rotatable holding device, by …

Entwicklung und Charakterisierung von mikrostrukturierten Planarspulen für Kernspinresonanz-Anwendungen
… low field devices, commonly based on solenoid coils of conventional copper wire, have already been developed to analyse centimetre-sized objects. However, the demand for a portable device, which enables a millimetre-sized structure analysis, was not fulfilled, especially to image small …

Time resolved electrical injection of coherent spin packets through a Schottky barrier
… to be taken into account for the design of high-frequency spintronic devices. Electrical injection by repetitive voltage pulses leads to interference of the injected spins yielding resonant spin amplification (RSA), if the Larmor frequency is in resonance with the pump repetition frequency. …
