Abstract

From the perspective of marketing, it is of high interest to install a 3 Tesla Magnetic Resonance Imaging system in a mobile trailer. At present, the imaging performance in mobiles is not as good as in static setups. One reason for this is the unfavorable floor-borne vibration environment for the mobile magnet. Ambient vibration levels and frequencies vary between different sites, with additional sources of vibration from trailer facilities (e.g. air conditioning units and water chiller).

Feet Locks for a Mobile MRI-System

Idea: Neil Tigwell, GB-Oxford; Stephen Trowell, GB-Oxford; Jeremy Williams, GB-Oxford

From the perspective of marketing, it is of high interest to install a 3 Tesla Magnetic Resonance Imaging system in a mobile trailer. At present, the imaging performance in mobiles is not as good as in static setups. One reason for this is the unfavorable floor-borne vibration environment for the mobile magnet. Ambient vibration levels and frequencies vary between different sites, with additional sources of vibration from trailer facilities (e.g. air conditioning units and water chiller).

Currently, it is not possible to mount mobile magnets on anti vibration mounts since the magnets would move excessively during transit.

We propose to use the anti vibration mounts as used on static sites on mobile systems, by including a locking device that clamps the OVC foot to the floor of the trailer via bump-stops whilst the system is in transit. Before imaging starts, the clamp will be disengaged.

To ensure that the system cannot be moved without the clamps engaged, a preferred embodiment will include interlocks coupling the clamps to the vehicle immobilizer. The clamps may be arranged to release automatically when power for the imaging process is connected.
