dc.description.abstractEl propósito de este estudio es brindar una solución de software para la prescripción eficiente de TAC en pacientes de trauma en la zona craneomaxilofacial. La utilización de las TAC es cada vez más importancia, no solo en el diagnóstico de enfermedades y patologías de los órganos internos, sino en el desarrollo de tecnologías y técnicas para realizar cirugías mucho más precisas a través de planeación o de diseño de implantes a medida. Sin embargo, se siguen presentando inconvenientes en la toma y la transmisión de las mismas y eso impacta negativamente al paciente y al sistema de salud. El estudio hace un recuento histórico sobre la incidencia de esta técnica radiológica en la salud y analiza la frecuencia con que se prescriben estos exámenes, la radiación a la que son expuestos estos pacientes y la incidencia que tiene en la radiación general de la población. Por otro lado se estudian estándares y elementos técnicos de los TAC en la bibliografía y su relación con las técnicas de reconstrucción digital. Así mismo, se analizan los metadatos de 50 tomografías de pacientes de trauma, que son candidatos para el diseño de un implante a medida, para establecer un comparativo entre estos y los estándares establecidos a través de la bibliografía. Finalmente, se realiza el diseño de una herramienta tecnológica que involucre los hallazgos de la bibliografía y el estudio de las tomografías, orientada a los profesionales involucrados en la prescripción, transmisión y toma de TAC, como médicos cirujanos y tecnólogos en radiología. Las limitaciones del estudio están dadas por la bibliografía encontrada hasta el momento y las condiciones y la cantidad de tomografías analizadas.
dc.description.abstractenglishThe purpose of this study is to provide a software solution for efficient CT prescription in craniomaxillofacial trauma patients. The use of CT scans has become increasingly important, not only in the diagnosis of diseases and pathologies of internal organs, but also for technologies and techniques to perform much more precise surgeries through planning or designing custom implants. However, problems with continue to arise in CT taking and transmitting and this negatively impacts the patient and the health system. The study provides a historical account of the impact of this radiological technique on health and analyzes the frequency with which these tests are prescribed, the radiation to which these patients are exposed and the impact this has on the general radiation of the population. On the other hand, standards and technical elements of CT scans are studied in the bibliography and their relationship with digital reconstruction techniques. Likewise, the metadata of 50 tomography scans of trauma patients, who are candidates for the design of a custom implant, are analyzed to establish a comparison between these and the standards established through the literature. Finally, the design of a technological tool is carried out involving the findings of the bibliography and the study of tomography scans, aiming to attend professionals involved in the prescription, transmission and taking of CT scans, such as surgeons and radiology technicians. The limitations of the study are given by the literature found to date and the conditions and number of tomography scans analyzed.
