Assessment of Tissue Oxygenation Using Multispectral Imaging

Descripción
The MultIspectral MObile tiSsue Assessment (MIMOSA) Imager acquires digital images to calculate anatomical details of chronic wounds (e.g. diameter, surface area, and perimeter). The device can be worn from a lanyard, and clips onto a smartphone, using natural ambient lighting to capture images of a wound. The MIMOSA also uses up to 6 near-infrared LEDs to illuminate tissue with different wavelengths of light to assess tissue oxygenation.
The Food and Drug Administration (FDA) has previously approved a near-infrared device called the Kent camera for the assessment of tissue oxygenation. The goal of this proposal is to assess tissue oxygenation in a group of healthy volunteers with both the MIMOSA near-infrared imaging device and the Kent Camera.
The investigators hope to show that the MIMOSA Imager is substantially equivalent to the Kent Camera, and as such, the investigators are modeling the investigator's experiments on data previously published by the makers of the Kent Camera. The MIMOSA Imager is a contact-less device, and differs from the Kent Camera only in that it is smaller and more portable.
