“…(Boersma 2000;Luhmann 2010;Davis et al 2013). El riesgo de infección asociado a la utilización de la fotogrametría es mínimo, pero esta técnica hasta ahora ha sido poco aplicable a la medición de úlceras en investigación o clínica, debido al tiempo, habilidad y coste del equipamiento necesarios para la configuración y puesta a punto del sistema, así como la toma y procesamiento de datos (Shaw and Bell, 2011, Mitchell and Newton 2002, Marjanovic et al 1998, Kecelj-Leskovec 2007.…”

Abstract:Geomatics includes techniques such as photogrammetry, remote sensing and geographic information systems, which provide applicable tools in various areas of biomedicine, for example skin ulcer measurement. In previous projects we developed procedures for acquiring data and measuring skin ulcers using a digital photo camera, a manual scanner and photogrammetry software based on correlation. We have tested our technique in a randomized clinical trial in patients with chronic leg ulcers. In the present project an application system is created with the following objectives: automate the processing of three-dimensional models of cutaneous ulcers and generate documentation that ease the interpretation of the evolution of skin ulcers by medical personnel (including PDF report, AVI animation and XOS augmented reality project). We also created a website prototype that stores the documentation, allowing registered users to upload photographs and consult or modify the database of skin ulcers. A test is performed with 50 cutaneous leg ulcers, in order to debug and improve the application system and the website prototype.Key words: Skin ulcers, Wounds, 3D Modelling, Geomatics, Photogrammetry Resumen:La geomática utiliza técnicas como la fotogrametría, teledetección y sistemas de información geográfica, que proporcionan herramientas aplicables a diversas áreas de la biomedicina como, por ejemplo, la medición de úlceras cutáneas. En proyectos anteriores desarrollamos los procedimientos de toma de datos y medición de las dimensiones de las úlceras mediante cámara fotográfica digital, escáner manual y software fotogramétrico de escaneado basado en correlación. Hemos probado nuestra técnica en un ensayo clínico aleatorizado realizado en pacientes con úlceras crónicas de la pierna. En el presente proyecto se crea un sistema de aplicaciones con los siguientes objetivos: automatizar el procesamiento de los modelos tridimensionales de las úlceras cutáneas; generar una documentación que facilite la interpretación de la evolución de la úlcera cutánea por personal médico (incluyendo informe PDF, animación AVI y proyecto de realidad aumentada XOS). También se crea un prototipo de página web que almacene la documentación, permita subir fotografías y consultar o modificar la base de datos de úlceras cutáneas. Se realiza una prueba con datos de 50 úlceras cutáneas de pierna, para depurar y mejorar el sistema de aplicaciones y el prototipo de página web.

“…For such applications, it is important that the system allows the acquisition of multiple digital images, which then would seamlessly integrate into one large image presenting the clinician with a simplified solution minimizing disruption of the clinical work flow. The proposed solution would also be helpful to address body contours where photographs may be acquired at different planes, yet the software algorithm would include stereo-photogrammetry 14 such that the physician may visualize a flat image of the large wound across different planes of the body. Second, some of the above-mentioned platforms include a digital camera equipped with lasers.…”

Background Wound assessment relies on visual evaluation by physicians. Such assessment is largely subjective and presents the opportunity to explore the use of emergent technologies. Methods Emergent and powerful noninvasive imaging technologies applicable to assess burn and chronic wounds are reviewed. Results The need to estimate wound depth is critical in both chronic wound and burn injury settings. Harmonic ultrasound technology is powerful to study wound depth. It addresses the limitations of optical imaging with limited depth of penetration. What if a wound appears epithelialized by visual inspection, which shows no discharge yet is covered by repaired skin that lacks barrier function? In this case although the wound is closed as defined by current standards, it remains functionally open, presenting the risk of infection and other postclosure complications. Thus, assessment of skin barrier function is valuable in the context of assessing wound closure. Options for the study of tissue vascularization are many. If noncontact and noninvasive criteria are of importance, laser speckle imaging is powerful. Fluorescence imaging is standard in several clinical settings and is likely to serve the wound clinics well as long as indocyanine green injection is not of concern. A major advantage of harmonic ultrasound imaging of wound depth is that the same system is capable of providing information on blood flow dynamics in arterial perforators. Conclusion With many productive imaging platforms to choose from, wound care is about to be transformed by technology that would help assess wound severity.

“…Whilst there is evidence on its use in chronic wounds [40], there is limited research on its potential as a burn wound mapping tool in pediatric populations [41]. 3D photography has the potential advantage over digital planimetry due to its ease of use at the bedside, non-invasive pointand-shoot method, increased accuracy of measurement, and its ability to store wound progression photographs.…”

“…Preliminary research has found excellent inter-rater reliability in patients with chronic wounds [40]. Additionally, a recent paper by Stockton et al [120] established the validity and reliability of 3D photography as a measure of acute burn wound surface area in children with acute burn injuries compared to the clinical gold standard digital planimetry (Visitrak™).…”

Repeatability and clinical utility in stereophotogrammetric measurements of wounds

Abstract: These preliminary findings suggest that 3D wound measurement minimises differences in wound measurement between expert and non-expert observers, suggesting it could be implemented with high reliability in health-care settings where several observers are involved in wound care management.
