1. A surgical drape for use during magnetic resonance imaging comprises:
- a sheet of sterile flexible material having a mechanism for adhering said sterile sheet to skin of a patient, and having an area through which an incision is made during an operation on the patient; and
a flexible radio frequency coil tuned to a Larmor frequency of the magnetic resonance imaging and attached to said sterile sheet and surrounding the area.

Abstract
A radio frequency coil for an magnetic resonance imaging system is integrated into a disposable surgical drape to permit imaging during a surgical procedure. The drape is formed by two sheets of flexible material with an adhesive applied to an exposed surface for adhering the drape to skin of a patient. A flexible radio frequency coil, tuned to the Larmor frequency, is sealed between the two sheets and surrounds an area of the drape through which an incision is made during surgery on the patient. A layer of material that is resistant to penetration by surgical instruments covers and protects the radio frequency coil during surgery.

8. A surgical drape for use during magnetic resonance imaging and intended to be disposed of after a single use, said surgical drape comprising:
-
a first sheet of flexible material having first and second major surfaces with adhesive applied to the first major surface for adhering said first sheet to skin of a patient; a flexible radio frequency coil tuned to a Larmor frequency of magnetic resonance and applied to the second major surface of the first sheet and surrounding an area on the second major surface through which an incision is to be made during surgery on the patient; a layer of material that is resistant to penetration by surgical instruments covering exposed surfaces of said radio frequency coil for protection against accidental penetration; and a second sheet of flexible material bonded to said first sheet with said radio frequency coil being sandwiched in between the first and second sheets. - View Dependent Claims (9)
