First Claim
Patent Images
1. A radio frequency (RF) coil assembly for magnetic resonance imaging in an intraoperative setting, comprising:
- an absorbent member comprising an absorbent material;
an RF coil coupled to the absorbent member;
a connecting element comprising a wired connector operatively engaged with the RF coil, wherein the wired connector communicates signals between the RF coil and an RF controller, and maintains a visual indication of a location of the absorbent member relative to tissues adjacent the absorbent member;
wherein the absorbent member comprises a first layer and a second layer; and
wherein the first layer is composed of a first absorbent material and the second layer is composed of a second absorbent material, and wherein the RF coil is disposed between the first layer and the second layer.

Abstract
Radio frequency (“RF”) coil assemblies for use in local magnetic resonance imaging (“MRI”) of tissues in a subject or patient in an intraoperative setting are provided. One or more RF coils are coupled to an absorbent member. A connecting element is coupled to the RF coil(s) or the absorbent member. When connected to the RF coil(s), the connecting element includes a wired connector that communicates signals between the RF coil(s) and an RF controller. The RF coil assemblies can be made to be disposable.
