Provided is a circular pole piece that contributes to simplification of work and a reduction in costs and that has no gap created among adjoining blocks. A circular pole piece is manufactured by circularly arranging laminate blocks each having numerous hexagonal directional magnetic steel sheet tiles layered. Since heteromorphic soft magnetic material tiles are unnecessary, work can be simplified and the cost of the circular pole piece can be reduced. Moreover, the laminate blocks can be arranged substantially circularly without a gap among adjoining blocks.

Circular pole piece, laminate block manufacturing method, and MRI system

The temperature of permanent magnet blocks embedded in several positions in permanent magnets and base yokes will be adjusted by device of a heater to improve the static field uniformity.

Static field controlling method and MRI apparatus

For the purpose of always keeping the positional relationship fixed between a support section for supporting a supported object and a base section for receiving the support section, the present apparatus comprises: a support section for horizontally supporting a supported object; a base section having a horizontal plane on its top; and a position adjusting section provided between the support section and the base section, for moving the support section forward/backward between a position above the horizontal plane and a position off the horizontal plane while keeping the support section at a level higher than the horizontal plane, and for moving the support section upward/downward between a position higher than the horizontal plane and a position lower than the horizontal plane at the position off the horizontal plane.

Magnetic resonance magnet system and imaging apparatus with extendable patient support arms

In order to facilitate appropriate biopsy puncture in magnetic resonance imaging, a puncture needle support tool has a base member attached to an RF coil a slider attached to the base member movably in parallel to the axis of the RF coil, and a puncture needle guide having a puncture needle through hole and an MR marker disposed in parallel to the through hole, capable of linearly moving in a direction perpendicular to the sliding direction on the slider and of rotatively moving in a plane perpendicular to the axis of the RF coil.

Puncture needle support tool, RF coil, magnetic resonance signal measuring apparatus, and magnetic resonance imaging apparatus and method

The present invention is directed to joint motion imaging and provides a vertical magnet type MRI system comprising a vertical magnet unit ( ) having a pair of opposite vertical magnets ( ), a movable table ( ) provided with wheels ( ) for traveling and a cradle ( ) to carry a specimen laid down thereon, and capable of being moved into and moved out of a space between the pair of opposite vertical magnets ( ), table locking devices ( ) for locking the movable table ( ) with the cradle ( ) being in place between the pair of opposite vertical magnets ( ), a movable chair ( ) provided with wheels ( ) for traveling and capable of being moved into and moved out of the space between the pair of opposite vertical magnets ( ), and a chair locking device ( ) for locking the movable chair ( ) in place between the pair of opposite vertical magnets ( ).

Diagnostic system with a chair and table movable on rails provided on vertical magnets thereof

In order to prevent the extremity ends of the flexible members from striking against the side surfaces of the inspected body mounting table when the flexible members are developed, there is provided a radio frequency coil having a pair of flexible base plates FXB in which the cylinder is formed under a state of free ends of these pair of flexible base plates and they are developed into a sheet under a state of not connecting the free ends from each other, wherein there are provided the shape defining members FRM installed at a side inside the cylinder from the fixed ends of the flexible base plates to their free ends, and the sheet ENV applied at the inner side of the cylinder from the fixed ends to the free ends of the flexible base plates.

Radio frequency coil

In order not to nip the clothes or skin of a subject between the joining portions of coil members when a detecting coil for a magnetic resonance diagnostic apparatus is fitted around a region of the subject such as the leg or neck, the detecting coil 100 for a magnetic resonance diagnostic apparatus, which can be separated into an upper coil member 10 and a lower coil member 20 and has an annular shape when these members 10, 20 are integrally joined, is provided at the joining portions of the lower coil member 20 with guards 27, 28 of a silicone rubber having a hardness of Hs80.

Detecting coil for magnetic resonance diagnostic apparatus

For the purpose of supporting the subject's head corresponding to the motion of the subject's neck, there is provided a neck fixing apparatus comprising a base disposed on a surface on which the subject is mounted, an arm extending along the body axis of the subject to be mounted and pivotally attached to the base, and a head rest 82 for mounting the subject's head, movably attached to the arm and movable along the arm 60.
