Abstract

Se describen técnicas para controlar los componentes de un sistema de formación de imágenes por resonancia magnética (IRM) con un solo controlador, como una matriz de puerta programable de campo (FPGA), instruyendo dinámicamente al controlador para que emita comandos a los componentes utilizando un procesador acoplado al controlador; según algunos aspectos, el controlador puede emitir comandos a los componentes del sistema de IRM mientras recibe activamente comandos del procesador para luego ser enviados a los componentes.
