Title (EN) ELECTRIC IMPEDANCE IMAGING SYSTEM
(FR) SYSTEME D'IMAGERIE A IMPEDANCE ELECTRIQUE
Abstract: front page image
(EN)An electric impedance imaging system is presented in which the electrical permittivity and/or conductivity distribution is derived on the basis of magnetic resonance signals. The magnetic resonance signals are generated due to an excitation electro-magnetic field. Notably, a magnetic induction field strength is derived from the acquired magnetic resonance signals. Also the electrical field strength associated with the excitation electro-magnetic field is computed. The electrical permittivity and/or conductivity distribution is computed on the basis of the electric field strength and the magnetic induction field strength.
(FR)L'invention porte sur un système d'imagerie à impédance électrique dans lequel la répartition de la permittivité et/ou conductivité électrique est dérivée sur la base de signaux à résonance magnétique. Les signaux à résonance magnétique sont générés par un champ électromagnétique d'excitation. Il est à noter que l'intensité du champ à induction magnétique est extraite des signaux à résonance magnétique acquis. On calcule également l'intensité du champ électrique associée au champ électromagnétique d'excitation. La répartition de la permittivité et/ou conductivité électrique est calculée sur la base de l'intensité du champ électrique et de l'intensité du champ à induction magnétique.
