| 摘要 |
A method and medical device for detecting signals that detects emitted light scattered by a volume of tissue delivered along a first pathway and a second pathway different from the first pathway, detects emitted light scattered by a volume of tissue delivered along a third pathway and a fourth pathway different from the third pathway, determines a first uniformity corresponding to the emitted light detected along the first pathway and the second pathway, determines a second uniformity corresponding to the emitted light detected along third pathway and the fourth pathway, determines a total uniformity in response to the determined first uniformity and the determined second uniformity, and alters sensing by the device in response to the determined total uniformity.
