Abstract

La presente invención se relaciona con un aparato y método para alterar y/o detectar partículas magnéticas en un campo de visión (28), en particular para examen de pacientes humanos. El aparato comprende: i) un medio de selección y enfoque (120) para generar un campo de selección y enfoque magnético (50), en donde por lo menos un conjunto de bobinas de campo de selección y enfoque comprenden: - por lo menos una bobina de campo de selección y enfoque interna (113, 115) que está conformada como un circuito cerrado alrededor de un eje de bobina interno (115a), primera bobina de campo de selección y enfoque interna (115) - un grupo de por lo menos dos bobinas de campo de selección y enfoque externas (116 a 119) distribuidas a una distancia más grande de los ejes de bobina internos (115a) en comparación con por lo menos una bobina de campo de selección y enfoque interna (113, 115) y en posiciones angulares diferentes, cada una está conformada como un circuito cerrado alrededor de un eje de bobina externo asociado (116a a 119a), y ii) un medio impulsor (120) que comprende una unidad generadora de señal de campo de impulsión (122) y bobinas de campo de impulsión (124; 125, 126, 127) para cambiar la posición en el espacio y/o el tamaño de las dos sub-zonas (52, 54) en el campo de visión (28) por medio de un campo impulsor magnético de manera que la magnetización del material magnético cambie localmente.
