Title:
【発明の名称】磁気共鳴検査方法および装置
Document Type and Number:
Japanese Patent JP2866080
Kind Code:
B2
Abstract:
The invention relates to a process for magnetic resonance examinations, in particular nuclear spin tomography, whereby a static magnetic field is produced in an examination zone and at least one gradient magnetic field is superposed, whereby unwanted alternating electromagnetic forces are produced, whereby by means of magnetostriction, forces opposing the electromagnetic forces are produced by the same gradient magnetic field and these forces act longitudinally and/or radially and/or around the circumference of the examination zone. Furthermore, the invention relates to a device for magnetic resonance examinations, in particular nuclear spin tomography, with a first generating unit for a static magnetic field, a second generating unit (20) for at least one gradient magnetic field and a support unit (10) for the second generating unit (20), whereby a magnetostrictive material system (11, 12) is provided on the support unit (10).
