Abbreviations: (2D) two-dimensional, (3D) three-dimensional, (app) application, (EMR) electronic medical recordKeywords: diabetic foot, imaging, technology, wound healing, wounds AbstractA significant arising complication in the care of patients with diabetes is increased susceptibility to chronic wounds, including diabetic foot ulcers and pressure sores. This is driven by, e.g., neuropathy and peripheral arterial disease. It is well recognized that best practice in wound care requires wound assessment, including measurement, on presentation and regularly throughout the treatment program. Proper assessment is necessary to ensure that the most appropriate and cost-effective therapy is used at all times, with quantitative measurement necessary to track the efficacy of the chosen approach. A documented assessment can also assist patient-clinician dialog and discussion within the multidisciplinary team. Remote evaluation and assessment of the wound is also of increasing importance and practicality through the use of a telemedicine approach. There has been considerable progress in the space of imaging for wounds, including systems that include threedimensional measurement and telemedicine features. This literature review examines the available options and reviews the clinical evidence for measurement accuracy, scope for remote assessment, and published user feedback on the systems. J Diabetes Sci Technol 2013;7(5):1190-1194 SYMPOSIUMFoot ulcers are one of the most common complications of diabetes, affecting up to 25% of patients during their lifetime 1 and frequently resulting in hospitalization. 2-4Diabetic foot ulcers are also associated with significant morbidity and mortality, 5 with 80% of all diabetes-related lower extremity amputation being preceded by a foot ulcer. 6 Together with prevention strategies, proper management must be a mainstay in the approach to curbing the burden associated with foot ulcers.Accurate recognition and monitoring of ulcer characteristics facilitates benchmarking therapeutic response. Further, if research into new agents/interventions for wound healing should continue to inform practice, it is essential that ulcer characteristics are well defined in order to (i) enable comparison between studies, (ii) determine which patients/ulcers derive the most benefits from a particular therapeutic approach, and (iii) allow accurate monitoring of wound healing in order to guide clinical decision making.

The importance of effective surgical wound care cannot never be underestimated. Poorly managing surgical wounds may cause many serious complications. Thus, it raises the necessity to develop a patient-friendly self-care system which can help both patients and medical professionals to ensure the state of the surgical wounds without any special medical equipment. In this paper, a surgical wound assessment system for self-care is proposed. The proposed system is designed to enable patients capture surgical wound images of themselves by using a mobile device and upload these images for analysis. Combining image-processing and machine-learning techniques, the proposed method is composed of four phases. First, images are segmented into superpixels where each superpixel contains the pixels in the similar color distribution. Second, these superpixels corresponding to the skin are identified and the area of connected skin superpixels is derived. Third, surgical wounds will be extracted from this area based on the observation of the texture difference between skin and wounds. Lastly, state and symptoms of surgical wound will be assessed. Extensive experimental results are conducted. With the proposed method, more than 90% state assessment results are correct and more than 91% symptom assessment results consistent with the actual diagnosis. Moreover, case studies are provided to show the advantage and limitation of this system. These results show that this system could perform well in the practical self-care scenario.Index Terms-Artificial intelligence (AI), classification, health care service systems.

“…Many researchers simply neglected the scattering effect as they estimated wound tissue topography using various 3-D imaging techniques such as multiview imaging, laser scanning, and structured light illumination. [17][18][19][20] By using polarized light and combining multiple imaging modalities, it is possible to acquire only the surface reflectance of biological tissue for reducing imaging distortion in 3-D reconstruction and for obtaining other pathophysiologic information of biological tissue. 14…”

Accurate and in vivo characterization of structural, functional, and molecular characteristics of biological tissue will facilitate quantitative diagnosis, therapeutic guidance, and outcome assessment in many clinical applications, such as wound healing, cancer surgery, and organ transplantation. We introduced and tested a multiview hyperspectral imaging technique for noninvasive topographic imaging of cutaneous wound oxygenation. The technique integrated a multiview module and a hyperspectral module in a single portable unit. Four plane mirrors were cohered to form a multiview reflective mirror set with a rectangular cross section. The mirror set was placed between a hyperspectral camera and the target biological tissue. For a single image acquisition task, a hyperspectral data cube with five views was obtained. The five-view hyperspectral image consisted of a main objective image and four reflective images. Three-dimensional (3-D) topography of the scene was achieved by correlating the matching pixels between the objective image and the reflective images. 3-D mapping of tissue oxygenation was achieved using a hyperspectral oxygenation algorithm. The multiview hyperspectral imaging technique was validated in a wound model, a tissue-simulating blood phantom, and in vivo biological tissue. The experimental results demonstrated the technical feasibility of using multiview hyperspectral imaging for 3-D topography of tissue functional properties.
