摘要:
The invention relates to a Faraday cage, particularly for Nuclear Magnetic Resonance applications, having walls which delimit a room, said walls being at least partially made of an electrically conductive material and connected to the ground or to a predetermined potential. According to the invention, the Faraday cage has a floor which rests at least partly on the ground and has such a construction that the weight is spread all over its surface. According to a further characteristic, the floor wall is load-bearing and preferably consists of crossed load-bearing beams and load bearing panels therebetween. The floor is electrically conductive and is connected at least electrically to the other walls of the cage.

A magnetic resonance imaging apparatus including a magnetic structure having two opposite and spaced apart poles and a column or wall transverse to the poles and connecting the poles; the poles defining two opposite walls delimiting a patient-imaging space, the two opposite walls extending along substantially parallel planes which are substantially parallel to a vertical plane; and a patient positioning table which is slidably connected to a supporting frame between the two poles; the table being positioned with its longitudinal axis substantially parallel to the two opposite parallel walls of the poles and the table being oriented with its transverse axis perpendicular to at least one of the two opposite walls.

A magnetic resonance imaging apparatus includes a magnet having a two poles and a wall connecting the poles; the poles delimiting a patient-imaging space; and a table which is slidably connected to one of the two poles between the two poles and which table extends substantially parallel to the two poles; a drive for displacing the table relative to the magnet; a lock for locking the table in a selected position relative to the magnet; a drive for rotating the magnet about the axis; the table connected to the magnet such that the table rotates with the magnet when the magnet rotates about the axis; the magnet and the table being rotatable from a position in which the poles and the table are horizontal to a position in which the table and the poles are vertical.

摘要:
Nuclear Magnetic Resonance imaging apparatus of the type for imaging specific parts of the body, the device including a magnetic structure (1), having a cavity (101) for accommodating the limb part to be examined, which may be accessed from the outside, and in which, or at least in one part of which (V) the necessary magnetic fields are generated. The magnetic structure (1) is supported in such a manner as to be able to oscillate (O) about a horizontal axis, which is parallel to the static magnetic field, whereas the axis of oscillation (O) is staggered with respect to the central axis, which is parallel thereto and passes through the cavity volume (V), wherein the static magnetic field has the characteristics required for valid imaging, to such an extent that the relevant volume (V) moves from an uppermost position to a lowermost position, the two extreme positions as well as those intervening therebetween being adjusted to the head and/or neck and/or upper limbs level in the standing and/or sitting positions of the patient and to the lower limbs level in the standing and/or sitting positions of the patient respectively.

摘要:
A patient table is used in combination with a biomedical apparatus such as a magnetic resonance imaging machine. The table includes a supporting surface sized to accommodate at least a part of the patient's body. At least one recess is formed in one or more areas of the supporting surface, these recesses being open at the peripheral edge of the supporting surface. The table is formed of first and second parts that can be angled relative to one another. The table can be swung horizontally to relative positions relative to the machine and locked in selected ones of the positions.
