Abstract

In order to improve quality of a medical image, obtained by magnetic resonance, several factors can be modified, in particular the homogeneity of the value of the static field, the technique of acquisition with its parameters, the sensitivity of the reception antenna. On this last factor there remains progress very significant to achieve. In order to calculate with more precision the signal collected by the reception antenna, a new numerical approach is described. We use the coupling of the two methods finite elements-boundary integral to calculate the magnetic flux induced by the magnetization of the sample and receipt by the antenna. Numerical results for a tone antenna are presented
