Abstract
Signals in an RF field, such as that of an MRI system, are communicated through an inner conductor having an outer shield with a dielectric material therebetween and an outer cable jacket. Current in the shield caused by the RF field from the transmit body coil is reduced by providing a second dielectric material around the shield conductor and a plurality of segmented shield conductor portions formed of non-magnetic braid or wrapped non-magnetic foil tape outside the second dielectric material and inside the jacket at spaced positions along the cable, with the portions being electrically separated from each other and from the shield so that the segmented shield conductor portions act to shield the outer shield conductor to reduce the generation of current thereon while the electrical separation of the segmented shield conductor portions each from the others prevents the generation of a current along the portions.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
