INJECTOR WITH PIEZO MOTOR SYSTEM WITH WAVE FORM TUNING

摘要

A piezo motor (150) may be tuned to a specific frequency range having a small deviation from an operational frequency range of a magnetic resonance imaging system component. This may be done by applying a pressure to the piezo motor (150), generating at least one signal via a control board (200) and where this signal is at a selected frequency within the specific frequency range applying the signals to the piezo motor (150), measuring a vibration frequency of the piezo motor (150), and varying the applied pressure to the piezo motor (150). The applied pressure may continue to be adjusted until the measured vibration frequency of the piezo motor (150) is at a resonant frequency for the piezo motor (150). After the piezo motor (150) is tuned in this manner, the piezo motor (150) may be incorporated into a magnetic resonance imaging system component.
