Extendable radiofrequency shield for magnetic resonance imaging device
First Claim
1. A radiofrequency (RF) shielding channel for a magnetic resonance imaging (MRI) device, the RF shielding channel comprising:
- at least one conductive layer having a proximal end and a distal end, the at least one conductive layer extendable in a longitudinal direction with respect to a bore of the MRI device between a first predetermined longitudinal dimension and a second predetermined longitudinal dimension; and
a connector to connect the proximal end of the at least one conductive layer to the bore of the MRI device, such that a RF shield is formed from the bore of the MRI device to the distal end of the at least one conductive layer upon extension of the at least one conductive layer to the second predetermined longitudinal dimension such that RF radiation emitting from the bore is substantially prevented from exiting the distal end of the at least one conductive layer, and RF radiation emitting from an environment external to the MRI device is substantially prevented from entering the bore.

Abstract
A radiofrequency (RF) shielding channel for a magnetic resonance imaging (MRI) device is provided. The RF shielding channel can include at least one conductive layer having a proximal end and a distal end. The RF shielding channel can include a connector to removably attach the proximal end of the at least one conductive layer to a bore of the MRI device. The at least one conductive layer can be extended in a longitudinal direction with respect to the bore of the MRI device between a first predetermined longitudinal dimension and a second predetermined longitudinal dimension, such that a RF shield is formed from the bore of the MRI device to the distal end of the at least one conductive layer. The RF shield can prevent an external RF radiation from entering the bore of the MRI device and/or an RF radiation emitted by the MRI device from exiting the bore.
