Abstract

Un motor piezoeléctrico (150) se puede afinar a un intervalo de frecuencia específico que tiene una desviación pequeña de un intervalo de frecuencia operativa de un componente del sistema de imagenología de resonancia magnética. Esto se puede realizar al aplicar una presión al motor piezoeléctrico (1509, generar por lo menos una señal a través de un tablero de control (200) y donde esta señal está a una f4recunecia especifico que aplica las señales al motor piezoeléctrico (150), medir una frecuencia de vibración del motor piezoeléctrico (150) y varia r la presión Aplicada al motor piezoeléctrico (150). La presión aplicada puede continuar siendo ajustada hasta que la frecuencia de vibración medida del motor piezoeléctrico (150) se afina de esta manera, el motor piezoeléctrico (150) se puede incorporar en un componente del sistema de imagenología de resonancia magnética.
