AI Technical Summary

Technical Problem

In existing transportation solutions for magnetic resonance imaging equipment, gradient coils are prone to rotation or displacement due to vibration, leading to component damage. Furthermore, existing fixing solutions are complex in structure and difficult to install.

Method used

The limiting assembly consists of an air cushion unit and a sensor. When the air cushion is inflated, it compresses the gradient coil and magnet, preventing them from moving. The sensor monitors the air pressure and displays the air pressure value through an indicator, simplifying the installation process.

Benefits of technology

It effectively prevents the gradient coil from rotating and shifting during transportation. It has a simple structure, is easy to install, and reduces the risk of component damage and operational difficulty.

Abstract

A limiting assembly for transporting a magnetic resonance imaging device includes an air cushion unit. The magnetic resonance imaging device includes gradient coils and a magnet. The gradient coils are spaced apart within a magnet bore of the magnet, and the air cushion is positionable in a gap between the gradient coils and the magnet. The air cushion is configured such that, in an inflated state, two surfaces of the air cushion are able to press against the gradient coils and the magnet, respectively, to inhibit movement of the gradient coils relative to the magnet during transport. A sensor is mountable to the air cushion to monitor air pressure within the air cushion and generate a signal related to the air pressure. The limiting assembly is simple in structure and easy to install.
