Abstract
En una modalidad de ejemplo, una herramienta de adquisición de registros por resonancia magnética nuclear (RMN) comprende un arreglo de uno o más imanes que genera un campo magnético estático (B0) en un cuerpo material. Un par de primera y segunda bobinas de antena se une a la herramienta alrededor de un núcleo de antena, en el que las espiras de la primera y la segunda bobinas de antena no se encuentran alineadas con un eje longitudinal de la herramienta o un eje ortogonal sustancialmente transversal a este. Un circuito acciona el par de la primera y la segunda bobina de antena en conjunto para producir un campo de radiofrecuencia (B1) en el cuerpo material. En una modalidad, las espiras en la primera bobina de antena se encuentran separadas de las espiras correspondientes en la segunda bobina de antena enrollada en sentido opuesto por un ángulo (a). En una modalidad de ejemplo, se selecciona el ángulo (a) para minimizar un consumo de energía de la herramienta o maximizar uno o más de SNR/eco, (I), SNR/tiempo o (II) de la herramienta para una configuración predeterminada del arreglo de imanes y el núcleo de antena de la herramienta.
