Treball Final de Grau en Medicina. Codi: MD1158. Curs acadèmic: 2020/2021 Introducción El desarrollo de la tecnología 3D está en auge desde hace unos años. En el ámbito médico, ha demostrado ser beneficiosa en diferentes sectores, siendo uno de ellos el tratamiento quirúrgico. Las intervenciones quirúrgicas más sencillas requieren destreza manual y capacidad de compresión anatómica, muchas veces alcanzables únicamente con la práctica repetida. Esta práctica se dificulta en el caso de patología sobre variantes anatómicas poco comunes en la población general o en localizaciones complejas, como ocurre en la patología de cadera. Objetivos La necesidad de planificación prequirúgica y desarrollo de habilidades manuales puede justificar la necesidad de un protocolo que permita al médico especialista de COT conocer las herramientas necesarias para obtener su propio modelo anatómico 3D y cómo utilizarlas de manera sencilla. Métodos Tras una búsqueda bibliográfica en PubMed sobre las aplicaciones de la impresión 3D (I3D) en medicina, las técnicas y materiales empleados, junto con recomendaciones y tutoriales de equipos hospitalarios con cierto recorrido en este ámbito, se realizó un protocolo para la obtención de modelos 3D a partir de imágenes TAC. Conclusiones La fabricación de modelos 3D en los servicios hospitalarios particulares es un proceso sencillo y rápido, que ha demostrado ofrecer beneficios tanto para los especialistas (mejora de habilidades prácticas) como para los pacientes (mejores resultados quirúrgicos). Introduction Development in three-dimensional (3D) technology has been on the rise for a few years now. In the medical field, it has proven to be beneficial in different areas, one of them being surgical treatment. Simple surgical interventions require manual dexterity and anatomical understanding, often achievable only with repeated practice. This practice becomes difficult in the case of pathology on uncommon anatomical variants among the general population, or in complex locations, as is the case of hip pathology. Objectives The need for pre-surgical planning and development of manual skills may justify the elaboration of a protocol allowing a specialist in orthopaedic surgery and traumatology to be familiar with the tools necessary to obtain their own 3D anatomical model as well as their usage in a simple way. Methodology A literature search in PubMed on the applications of 3D printing in medicine and its techniques and materials employed was conducted. Together with the recommendations and guidelines from hospital teams with certain experience in this field, a protocol was drawn up for obtaining 3D models from CAT images. Conclusions The fabrication of 3D models in different hospital services is a simple and fast process which has proven to offer benefits for both specialists (improved practical skills) and patients (better surgical outcomes) alike.

The methods and tools that assists during the non-invasive determination of functional regions in cases of refractory epilepsy are essential. Along with this train of thought, a new method is presented for the dynamic visualization of the electric map and its incorporation in a multimodal scene using free image processing tools, such as VTK and Python. From the electric map andgeometry generated by Brainstorm the registration is done obtaining different transformation matrices and with them three-dimensional surface files are written along with the information of the electric map. The visualization together with the rest of the patient's co-registered imaging studies can be integrated into a multimodal free viewer, such as 3D Slicer. In this work, the procedure performed is described., Special Issue dedicated to JAIIO 2018., Sociedad Argentina de Informática e Investigación Operativa
