Magnetic resonance imaging device

摘要

The magnetic resonance imaging device of the present invention includes a gantry and a bed part comprising a top panel, the gantry comprises a circumferential panel covering outer circumference of a tunnel-shaped static magnetic field space, and a front panel having an opening serving as entrance of a bore for the static magnetic field space, this front panel comprises an arc-shaped outer panel extending from an upper part of the opening serving as entrance of the bore to the ground plane via both sides of the opening, and an inner panel disposed inside the outer panel, a portion connecting the outer panel and the inner panel constitutes a top surface protruding forwardly, and the inner panel is formed in a recessed shape with a concave curved surface extending from the top surface to the opening serving as entrance of the bore.

主权项

1. A magnetic resonance imaging device comprising:
a gantry containing a static magnetic field generating source for forming a static magnetic field space; and a bed part having a top panel for placing a subject and inserting the subject into the static magnetic field space, wherein the gantry includes a front panel having an opening serving as an entrance of an open-part for the static magnetic field space, and at least a portion of the front panel around the opening is formed in a recessed shape, wherein the front panel comprises an arc-shaped outer panel extending from a position above the opening and passing around both sides of the opening to a ground plane, and an inner panel disposed inside the arc-shaped outer panel, and wherein a forwardly protruding top surface connects the outer panel and the inner panel, and the inner panel has a concave curved surface extending from the top surface to the opening to define the recessed shape of the front panel around the opening.
