摘要： Systems and methods for determining physiological parameters of a subject using a sensor array. In an embodiment, a sensor array may contain sensor elements for determining multiple physiological parameters. A combination of sensor elements and the physiological parameters determined may be selected based on signals obtained from the sensor elements of the sensor array. A sensor array may be connected to a monitoring device that may select an optimal sensor element or combination of sensor elements and one or more physiological parameters to be determined. The monitoring device may then determine physiological parameters using the selected combination of sensor elements and display information associated with the parameters on a monitor for use, for example, in monitoring a medical patient.

摘要： The present disclosure describes systems and methods that use spatial modulation to focus continuous wave light into a localized region of interest such as an individual blood vessel. In certain embodiments, intensity modulation techniques, such as linear frequency modulation, are used in conjunction with spatial modulation to achieve more precise measurements through otherwise scattering medium. The focused beam of continuous wave light is capable of penetrating several centimeters of tissue to deliver measurements and images associated with individual blood vessels and other discrete vascular components.

摘要： A physiological monitoring system may perform an optical measurement of a subject to assist a photoacoustic analysis of the subject. For example, an oblique-incidence diffuse reflectance measurement, photon density wave measurement, or other optical measurement may be used to determine one or more optical properties of a subject. Accordingly, the one or more optical properties may be used to determine an optical fluence at a region of the subject. In some arrangements, a physiological monitoring system may include an oximeter, and may use a calculated blood oxygen saturation value to assist a photoacoustic analysis. Photoacoustic analysis may include determining one or more physiological parameters based on a detected acoustic pressure response of a subject to a photonic signal via the photoacoustic effect.
