Abstract
A cable guide for use in a nuclear magnetic resonance tomography apparatus is provided for cable for making electrical connections between devices secured to a patient bed and devices disposed outside of the examination space. The cable guide is a grounded, electrical cable channel disposed beneath the patient bed and above the lower sub-antenna of a whole-body antenna and above at least one wall of the examination space. The cable channel has a V-shape, and is rounded at an edge facing the examination space, this edge projecting beyond the height of the lower sub-antenna. The cable guide substantially protects the cable against coupling with other components. The examination space remains free of built-in units.
Claims17
In a nuclear magnetic resonance tomography apparatus having a magnet with a central opening defining an examination space and having a patient support movable into said examination space, said opening having a wall on which a whole-body antenna divided azimuthally into a plurality of sub-antennas for generating a polarized field is attached, said sub-antennas including a lower sub-antenna disposed beneath said patient support when said patient support is in said examination space, said patient support having a plurality of electrical devices attached thereto and said apparatus having a plurality of further electrical devices disposed-outside of said examination space and connected to said electrical devices on said patient support via cables, the improvement of a cable guide for said cables comprising:
- a channel adapted to receive said cables disposed beneath said patient support and above said lower sub-antenna, said cable channel disposed at said wall of said examination space and having rounded edges projecting beyond the height of said lower sub-antenna said cable channel having a shape dependent on said polarized field.
In a nuclear magnetic resonance tomography apparatus having a magnet with a central opening defining an examination space and having a patient support movable into said examination space, said opening having a wall on which linearly polarizing whole-body antenna divided azimuthally into an upper sub-antenna and a lower sub-antenna is attached, said lower sub-antenna being disposed beneath said patient support when said patient support is in said examination space, said patient support having a plurality of electrical devices attached thereto and said apparatus having further electrical devices disposed outside of said examination space and means for connecting said further electrical devices to said electrical devices on said patient support via cables, the improvement of a cable guide for said cables comprising:
- a channel adapted to receive said cables disposed beneath said patient support and above said lower sub-antenna, said channel disposed at said wall of said opening and having a V-shape with a rounded edge facing said examination space, said edge projecting beyond the height of said lower sub-antenna.
In a nuclear magnetic resonance tomography apparatus having a magnet with a central opening defining an examination space and having a patient support movable into said examination space, said opening having a wall on which a circularly polarizing whole-body antenna is disposed, said whole-body antenna formed by a plurality of sub-antennas including a lower sub-antenna disposed beneath said patient support when said patient support is in said examination space, and neighboring sub-antennas respectively disposed at opposite ends of said lower sub-antenna, said patient support having a plurality of electrical devices attached thereto and said apparatus having further electrical devices disposed outside of said examination space and means for connecting said further electrical devices to said electrical devices on said patient support via cables, the improvement of a cable guide for said cables comprising:
- a channel adapted to receive said cables disposed beneath said patient support and above said lower sub-antenna, said channel having approximately a U-shape and being disposed at said wall of said opening between one end of said lower sub-antenna and a neighboring sub-antenna, said channel having edges respectively rounded toward said lower sub-antenna and said neighboring sub-antenna, said edges projecting beyond the height of said lower sub-antenna and said neighboring sub-antenna.
