Journal ArticleDOI
Ultra-fast imaging.
TL;DR: Including ultra-fast MR imaging techniques into the armamentarium of the radiologist will likely require changes to many aspects of theMRI practice, from expanded involvement with the scan process to management of the increased data load, and may lead to dramatic changes in the scope of the MRI practice.
Journal ArticleDOI
Cardiac Mechano-Electric Coupling: Acute Effects of Mechanical Stimulation on Heart Rate and Rhythm
T. Alexander Quinn,Peter Kohl +1 more
TL;DR: The power of computational modelling is demonstrated in developing a more comprehensive understanding of 'what makes the heart tick' and the implications of MEC in health and disease in human are presented.
Journal ArticleDOI
Occupational exposure in MRI
TL;DR: Modelling of induced electric fields from the imaging gradients shows that ICNIRP-induced field limits are unlikely to be exceeded in most situations; however, movement through the static field may still present a problem.
Journal ArticleDOI
Peripheral nerve stimulation by time-varying magnetic fields
J Abart,K. E. W. Eberhardt,H Fischer,Walter J. Huk,E Richter,Franz Schmitt,T Storch,Bernd Tomandl,E Zeitler +8 more
TL;DR: The hypothesis that orthogonal to the y-axis the body has its largest conductive loop, resulting in the strongest peripheral stimulation is supported.
Journal ArticleDOI
Closed-chest cardiac stimulation with a pulsed magnetic field.
G. A. Mouchawar,Joe D. Bourland,John A. Nyenhuis,Leslie A. Geddes,Kirk S. Foster,James Thomas Jones,George P. Graber +6 more
TL;DR: The threshold for cardiac stimulation by an externally-applied magnetic field is determined for 11 anaesthetised dogs and a margin of safety for devices that use pulsed magnetic fields is established and to design therapeutic devices employing magnetic fields to stimulate the heart is designed.

The specific resistance of biological material—A compendium of data for the biomedical engineer and physiologist
L. A. Geddes,L. E. Baker +1 more
TL;DR: The paper traces the history of, and tabulates determinations of the electrical resistivity of blood, other body fluids, cardiac muscle, skeletal muscle, lung, kidney, liver, spleen, pancreas, nervous tissue, fat, bone, and other miscellaneous tissues.
Journal ArticleDOI
Magnetic stimulation of the human brain and peripheral nervous system: an introduction and the results of an initial clinical evaluation.
TL;DR: The results of the first clinical study using magnetic stimulation show clear central motor pathway slowing in multiple sclerosis patients, and the technique is compared with conventional electrical stimulation.
Journal ArticleDOI
Myocardial stimulation with ultrashort duration current pulses.
TL;DR: A practical stimulus duration for minimum charge in the dog should be no longer than about two‐tenths of a millisecond, although shorter duration stimuli are equally effective this minimum charge criterion provides the minimum drain on the stimulator power supply.
