摘要

#CMT# #/CMT# The system has a basic field generating device (9) for generating basic magnetic field, and a gradient field generating device (8) for generating gradient field. The basic field generating device and the gradient field generating device are arranged in an evacuated low-pressure housing (2). A transmitter antenna (6) is arranged at an outside part of the low-pressure housing. Field screen elements (13) are provided between the basic field generating device and the gradient field generating device. The basic field generating device has smaller radius superconductive helium cooled solenoid coils. #CMT#USE : #/CMT# MRI system for investigating object i.e. patient. #CMT#ADVANTAGE : #/CMT# The basic field generating device is provided with smaller radius superconductive helium cooled solenoid coils so as to reduce outside dimensions and weight of the MRI system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a MRI system. 2 : Evacuated low-pressure housing 6 : Transmitter antenna 8 : Gradient field generation device 9 : Basic field generating device 13 : Field screen elements.
