Abstract:
A typical Magnetic Resonance Imaging (MRI) environment is demanding due to high static magnetic field, high field gradients and high strength radio frequency fields. In addition, an MRI is a sensitive diagnostic tool that must not be affected by the components at the proximity of the imaging area, leading to artifacts in the diagnostic image of the scanner. Actuator solutions for usage in the MRI imaging area, in particular travelling wave piezo motors, are available commercially; however they present numerous drawbacks. In this paper, a novel motor design based on the Piezo Actuator Drive (PAD) architecture is presented. It was tested in a Siemens 3T MRI. Results are presented and discussed. The results point that the motor can be used very close to the imaging volume without significant loss of performance and without affecting the medical diagnostic image.
