Indocyanine Green Sensor
Group 17
Abstract
Indocyanine Green Dye has a property that causes it to fluoresce under a specific range of
wavelengths, and is used in conjunction with a medical device, the SPYE camera system. The SPYE
Camera is a device used in surgery to allow surgeons to view the patient’s blood vessels. ICG is
injected into the patient, and the SPYE collects a specific wavelength of light from the ICG as it
fluoresces. This allows the SPYE to display a real time image of the patient’s blood vessels for the
surgeons to use as necessary. Our ICG Sensor is a miniaturization of the SPYE camera system, a
handheld sensor-emitter system that excites the ICG and displays the magnitude of fluorescence in
both numerical and graphical representations. This functionality can be used for measuring the
volume of blood flow, the decline in ICG concentration, or other useful data points.
