A CLEAR PICTURE
The images produced by an SFDI surgical camera show parameters such as oxygen saturation, water content and total hemoglobin. Despite advances in technology, burns remain difficult to treat, and CCCRP is exploring new ways to speed healing and reduce infection. (Photos courtesy of UC Irvine)
wait to take action, the infection rate goes way up over a few days. Te risk of scarring and all the nightmares that go along with scarring go up, too.” Accord- ing to the current standard of care, it can take up to three days after a burn for laser Doppler imaging to be performed, which determines whether the injured tissue is structurally sound enough to be reconstructed. So Durkin’s team devel- oped the cutting-edge spatial frequency domain imaging (SFDI) camera to assess the reconstructive potential of the tissue involved in burns and other wounds.
Te SFDI camera uses diffuse optical spectroscopy to take a snapshot of an affected burn area, with the resulting image providing an almost real-time visual map of parameters such as oxy- gen saturation, water content and total hemoglobin for each pixel. Clinicians can then evaluate
tissue viability in
wounded areas and determine whether that tissue is a suitable candidate for reconstructive surgery, all within just a few hours. “We think we can buy a couple of days that can dramatically decrease the risk of scars and infection,” Durkin said.
In addition to being a noninvasive technology, the SFDI can differentiate
between superficial partial thickness burns and deep partial thickness burns, a relatively muddy area of wound des- ignation within the medical community, according to Durkin. Te SFDI, which is being developed and commercialized by California-based Modulated Imaging Inc., recently received a grant to perform a tissue viability analysis in a variety of wounds relevant
to the military. As a
result, Durkin’s team has received FDA approval for its technology for research purposes and began efforts to secure FDA clearance for a miniature version of the same device at the end of 2017.
CONCLUSION Te fruits of the CCCRP’s military medi- cal mission often translate to the civilian world, and the lactate monitor is no exception. “Te diabetes community has caught on to what I’m doing,” Botvinick said, “and they’re very interested in knowing if lactate can help them safely control sugar and exercise routines in dia- betes patients.”
For as much effort and investment goes into the CCCRP’s litany of products and projects, so many of those same efforts— tourniquets, a balloon-tipped catheter that stops bleeding known as the REBOA and many knowledge products—have
gone on to improve and save the lives of countless American citizens.
While that is not the stated priority of the CCCRP and its associated technologies, it is a substantial benefit to the taxpaying public. After all, if a resilient military can help develop a resilient population which, in turn, continues to fuel an even more resilient military—that’s the very defini- tion of achievement.
