摘要:
A nuclear magnetic resonance imaging device has a magnetic structure which defines a cavity for housing at least part of the body of a patient with a magnetic field which permeates at least part of the cavity, an opening provides access to the imaging cavity from outside of the magnetic structure and electrically conductive and electrically grounded shielding provided at the opening is movable between a first inactive configuration wherein the opening is substantially open and an active configuration in which the opening is at least partially closed by the shielding

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.

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:
An examination table, particularly in Nuclear Magnetic Resonance image detecting machines of the so-called dedicated type, i.e. designed for detecting images of specific body parts, has an at least one-degree-of-freedom constraint (5, 6) to the machine (1), and has supports (6, 7, 12, 402, 302) which allow the examination table (2) to be moved in at least one, preferably two or more degrees of freedom. Advantageously, the examination table (2) is mounted in such a way as to be able to slide (7, 6) on a stationary guide (5) which is fixed with a predetermined orientation with respect to the detection cavity (101) of the machine (1) and it may be further translated in both senses (6, 7) along said guide (5) and rotated (11, 12) about an axis (402) perpendicular to the direction it follows while sliding on the guide (5).

The invention relates to a patient support device, for use with Magnetic Resonance imaging apparatuses, comprising a support surface (7) adapted to accommodate at least a part, particularly the whole of the patient body. According to the invention, this device comprises at least one, receptacles (307) for holding and/or removably coupling a coil (13′) adapted to receive signals from an anatomic region particularly from the spinal region, which receptacle (307) is arranged over the surface (7) of the patient support device in areas corresponding to the position of the anatomic region to be imaged. The invention also relates to a Magnetic Resonance imaging apparatus comprising a magnet structure (2) which delimits a cavity to receive at least a part of the patient body, in which an imaging volume is created. In accordance with the invention, the apparatus comprises a patient support device as defined in the invention and as described above. The invention further relates to a Magnetic Resonance imaging method providing the use of the apparatus and the patient support device according to the invention.
