MOBILE OPTICAL DEVICE AND METHODS FOR MONITORING MICROVASCULAR HEMODYNAMICS

摘要

A method implemented using a device to measure hemodynamic parameters is provided. The method includes transmitting, by the client device, a message to the server. The method includes capturing, by a camera, a first image of a plurality of images of a target region while two light emitting diode (LED) sensors emit light, via a collimated lens, on the target region. The method also includes capturing, by the camera, a second image of the plurality of images of the target region while the two LED sensors emit light, via the collimated lens, on the target region. The second image is captured a predetermined time after the first image is captured. The method further includes determining one or more hemodynamic parameters based on a difference between the first captured image and the second captured image.

1. A device to measure hemodynamic parameters, the device comprising:
a first light emitting diode (LED) sensor configured to emit light at a first wavelength (λ1); a second LED sensor configured to emit light at a second wavelength (λ2), wherein the first LED sensor and the second LED sensor are covered with a collimated lens; a camera; and a processor configured to:
control the camera to capture a first image of a plurality of images of a target region while the first LED sensor and the second LED sensor emit light on the target region;control the camera to capture a second image of the plurality of images of the target region while the first LED sensor and the second LED sensor emit light on the target region, wherein the second image is captured a predetermined time after the first image is captured; anddetermine one or more hemodynamic parameters based on a difference between at least the first captured image and the second captured image of the plurality of images.
