摘要：
A method for obtaining information about the position and / or orientation of a magnetic component (8) of a medical device with respect to a magnetometric detector (5), the magnetic component (8) and the magnetometric detector (5) being independently movable each other with respect to a static secondary magnetic field, the method comprising the steps of: - measuring in the presence of the combination of the magnetic field of the magnetic component (8) and the static secondary magnetic field essentially simultaneously the intensity and / or orientation of a magnetic field in at least a first position and a second spatial position associated with the magnetometric detector (5), the second position being separated from the first position； and - combining the measurements of the magnetic field to computationally eliminate the effect of the secondary magnetic field and adjusted to a magnetic field model of the magnetic component (8) to derive information about the position and / or orientation of the magnetic component (8)； characterized in that the medical device comprises as said magnetic component (8) a magnetized elongated medical device； and because said magnetic field model models the magnetic field as two separate magnetic charges, one of them being a tip of the elongated medical device.Un método para obtener información acerca de la posición y/o la orientación de un componente magnético (8) de un dispositivo médico respecto a un detector magnetométrico (5), siendo el componente magnético (8) y el detector magnetométrico (5) móviles independientemente entre sí respecto a un campo magnético secundario estático, comprendiendo el método las etapas de: - medir en presencia de la combinación del campo magnético del componente magnético (8) y del campo magnético secundario estático esencialmente de forma simultánea la intensidad y/o la orientación de un campo magnético en al menos una primera posición y una segunda posición espacial asociada con el detector magnetométri
