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.
