Abstract

El objeto principal de la presente invención se enmarca dentro del campo del diseño de bobinas magnéticas. En particular está dirigida a mejorar el diseño de bobinas magnéticas para poder alcanzar campos magnéticos elevados y muy rápidos. La presente invención mejora el diseño de uno de los componentes principales, sistema de bobinas de gradiente, de los equipos de imagen basados en la técnica de la resonancia magnética (RM). En esta invención se presenta una bobina magnética con configuración geométrica incompleta. La bobina magnética está caracterizada porque al menos uno de sus lóbulos está incompleto. El método de fabricación está basado en rellenado combinatorio. Además, la bobina magnética que se presenta en esta invención puede alcanzar gradientes magnéticos intensos y rápidos.
