Title:
MEDICAL INSTRUMENT FOR MRI
Document Type and Number:
WIPO Patent Application WO/2023/199936
Kind Code:
A1
Abstract:
In MRI, the current trend is for gantry magnetic fields to become increasingly stronger in order to enhance the detection accuracy. Thus, it is assumed that even objects referred to as non-magnetic, if electroconductive, may receive an unexpected force due to the magnetic field and perform a dangerous movement. This medical instrument for MRI used in an MRI diagnosis room has a leg in which plate-shaped components are placed upright and combined to form a cylindrical space, a column inserted into the cylindrical space, a leg wedge inserted between the column and the cylindrical space in a direction perpendicular to the direction in which the column is inserted into the cylindrical space, and a head that is fixed to the column and that is constituted from a stage plate and a body obtained by combining plate-shaped components in a grid pattern. The leg, the column, the leg wedge, and the head are non-metallic and insulating bodies. The medical instrument for MRI does not exhibit magnetization not only caused by a magnetic field but also caused by an eddy current, and can therefore be used safely in a strong magnetic field.
