A persistent issue with MRI scanners is inadequate vibration isolation. The objective of this work is to implement vibration isolation in a prototype MRI scanner base to minimize stringent and costly structural requirements for MRI suites. To first use a computational model of an MRI base as an analysis tool, modal analysis has been conducted to validate the model. Furthermore, analysis of a pneumatic isolator has been completed to assess its suitability to the MRI application. Testing demonstrated adequate performance of the isolator under most expected loading cases. Computational analysis of an idealized isolator model supports the experimental results.
