Abstract
B037 Numerical Modeling of Magnetic Resonance Signal from water-filled Cavities Summary 1 For the Magnetic Resonance Sounding method (MRS) a water-filled karstic cavity is a typical example of 2D/3D target. For practical purposes these cavities should be localized with very high accuracy. However due to a strong dependence on the geomagnetic field MRS performance is in turn dependent on the geographical location of investigated area. Efficiency of actually available MRS system with coincident transmitting/receiving loop applied to localization of 2D/3D structures with a size smaller than MRS loop size was studied numerically. It was shown that MRS results are sensitive
