About 500,000 Americans seek treatment for burns annually, but burn depth, used to create treatment plans and determine whether surgery is needed for treatment, is only correctly found about 50-80% of the time in the US. In the UK and other countries, clinicians have used laser doppler imaging (LDI) with clinical evaluation to increase diagnostic accuracy, however US based physicians tend to just use clinical evaluation, citing cost and difficulty of use as reasons for not using this technology. The purpose of this thesis is to present an innovative, cheap, and easy to use device that can be used to evaluate burn depth in a non-contact modality. When researching the pathophysiology of burn injuries, I found Jackson’s thermal wound theory, postulating that besides the degradation of proteins in the immediate environment, poor fluid flow is the next biggest challenge, without fixing more tissue will die. LDI uses this idea to look for fluid movement, while I planned to use this by finding water. The macro scale seemed to support this as well, burn victims with a significant amount of skin area burned lose so much fluid that they require IV fluid resuscitation for recovery. Based on this detection method, I created a device with a pair of LEDs that emit light at 910 and 970 nm, where 970 nm is a water absorption peak. To ensure that the device meets standards, a mathematical model was created and tested.
