Abstract
Various methods and systems for photoacoustic patient monitoring are provided. A photoacoustic system includes a light emitting component that emits one or more wavelengths of light into an interrogation region of a patient and an acoustic detector that detects acoustic energy generated by the interrogation region of the patient in response to the emitted light. The system also includes an optical detector that detects the emitted light and provides a signal that is used as an input to remove noise from the signal generated by the acoustic detector.
