Abstract
An assembly for delivering optical signals that has a nuclear magnetic resonance system, an optical interface assembly, and a catheter assembly with a fiber optic cable assembly and an optical interface and an antenna. The catheter assembly converts electromagnetic signals received by the antenna into optical signals. The optical interface assembly converts optical signals into electrical signals and electrical signals into optical signals.
Claims42
An assembly for delivering optical signals, wherein said assembly is comprised of a nuclear magnetic resonance system, a optical interface assembly electrically connected to said nuclear magnetic resonance system, and a catheter assembly connected to said optical interface assembly, wherein:
