Abstract:
Objective To develop a magnetic resonance imaging (MRI) system for pelagic definitive treatment platforms, large support ships and ocean vessels.Methods The system was designed based on normal electromagnetic MRI technology, which was composed of six parts of gradient system, magnet system, coil system, radiofrequency system, spectrum control system and imaging system.The magnet system was developed with C-shaped open magnet,five systems were designed such as a super-stability excitation system, a super-sensitivity signal detection system, a magnetic filed dissipation precision control system, a shipborne sensitive equipment vibration control system and a software system, and a set of technical detection standards was proposed.Results The developed MRI system realized mobile imaging,gained advantages in imaging velocity,resolution,magnetic field dissipation control,ship bump resistance and environmental suitability,and thus could be used in marine mobile conditions. Conclusion The developed MRI system meets the requirements of pelagic medical treatment, and contributes to improving pelagic medical support ability of Chinese navy.
