Abstract

La présente invention concerne un appareil d'imagerie médicale (100) comportant une sonde plane (104) configurée pour se placer sur une surface anatomique. Cette sonde est conçue, d'une part pour créer dans ce tissu un champ électromagnétique, et d'autre part pour acquérir des signaux permettant de cartographier la conductivité électrique du tissu.
