DESCRIPTION (provided by applicant): DFIS Eden Medical, Inc. is pleased to submit this revised Phase 2 SBIR proposal to develop the infrared "Diabetic Foot Imaging Scanner (DFIS)" to demonstrate the ability to capture dynamic thermal imagery and identify hot spots associated with repetitive stress. Diabetic foot wounds are common, complex and costly. Foot areas that are likely to ulcerate are associated with increased local skin temperature due to inflammation and enzymatic autolysis of tissue. Inflammation is characterized by the cardinal signs of: degree of redness, swelling, and heat. The key focus of DFIS imaging is to provide the capability to quantify all three signs of inflammation and identify pathological changes before they result in ulceration. The key goals of the proposed Phase 2 project are to: 1) to demonstrate the ability to capture dynamic thermal imagery of the feet, identify hot spots and inflammatory patterns in patients with diabetes; 2) to assess the quantification of wound healing using wound inflammatory index (Wii), a thermal index for diabetic foot wounds; 3) to associate the temporal behavior of Wii (quantified during wound healing) with 4 degree F home monitoring criteria for temperature differences between contra lateral sites on both feet during risk assessment phase with the intent to reduce ulceration risk.

描述(由申请人提供)：DFIS Eden Medical，Inc.很高兴提交这份修订后的第二阶段SBIR建议书，以开发红外“糖尿病足成像扫描仪(DFIS)”，以展示捕获动态热像和识别与重复应激相关的热点的能力。糖尿病足的伤口很常见，很复杂，而且费用高昂。足部容易溃烂的区域与局部皮肤温度升高有关，这是由于炎症和组织的酶促自溶。炎症的主要特征是：发红、肿胀和发热。DFIS成像的关键是提供量化所有三种炎症迹象的能力，并在导致溃疡之前识别病理变化。拟议的第二阶段项目的主要目标是：1)展示捕捉足部动态热图像的能力，识别糖尿病患者的热点和炎症模式；2)使用伤口炎症指数(Wii)来评估伤口愈合的量化，Wii是糖尿病足伤口的温度指数；3)将Wii的时间行为(在伤口愈合期间量化)与4华氏度家庭监测标准相关联，以降低溃烂风险。
