Abstract

In one embodiment, a medical device includes a first optical fiber, a second optical fiber, a third optical fiber, and a fourth optical fiber. The first optical fiber is operatively coupled to a first electromagnetic radiation source and is configured to transmit electromagnetic radiation to bodily tissue. The second optical fiber is configured to receive electromagnetic radiation from the first electromagnetic radiation source scattered by the bodily tissue. The third optical fiber is operatively coupled to a second electromagnetic radiation source and is configured to transmit electromagnetic radiation to bodily tissue. The second electromagnetic radiation source is different than the first electromagnetic radiation source. The fourth optical fiber is configured to receive electromagnetic radiation from the second electromagnetic radiation source scattered by the bodily tissue.
