Abstract
A standing wave barrier, particularly for use in a magnetic resonance tomography device, has a body and an opening in the body that is fashioned to accommodate a cable, the opening being formed as an externally open groove along a longitudinal direction of the standing wave barrier, and is shaped so that the cable can glide in and out along the standing wave barrier through the groove.
Claims15
A standing wave barrier to suppress standing waves on an electrically conducting cable, said standing wave barrier comprising:
- a body having an opening therein;
- and
- said opening in said body being shaped as an externally open groove in said body extending along a longitudinal direction of said body and having a shape to allow an electrically conductive cable in said groove to glide in and out of said body through said groove.
A magnetic resonance tomography apparatus comprising:
- a magnetic resonance data acquisition device comprising at least one cable in which a standing wave is produced during operation of said magnetic resonance data acquisition device;
- and
- a standing wave barrier comprising a body having an opening therein shaped to accommodate said cable therein, said opening being formed as an externally open groove extending a longitudinal direction of said body and having a shape to allow said cable to glide in and out along said standing wave barrier through said groove.
A magnetic resonance tomography apparatus as claimed in 10 wherein said transmission antenna has an effective length, and wherein said first standing wave barrier and said plurality of additional standing wave barriers, in combination, have a sum length that is at least as long as said effective length of said transmission antenna.
