ABSTRACT
The study on cadavers, although considered fundamental in the teaching of human anatomy, is limited in several universities, mainly due to the acquisition and manipulation of cadaveric material. Throughout history, several artificial anatomical models have been used to complement the real anatomical pieces. The present study offers a new alternative: the making of three-dimensional models from Computed Tomography (3D-CT) patient image acquisition. CT images from the USP University Hospital database were used. Patients underwent examinations for reasons other than the present study and were anonymized to maintain confidentiality. The CT slices obtained in thin cross-sections (approximately 1.0 mm thick) were converted into three-dimensional images by a technique named Volume Rendering for visualization of soft tissue and bone. The reconstructions were then converted to an STL (Standard Triangle Language) model and printed through two printers (LONGER LK4 Pro® and Sethi S3®), using PLA and ABS filaments. The 3D impressions of the thigh and leg muscles obtained better visual quality, being able to readily identify the local musculature. The images of the face, heart, and head bones, although easily identifiable, although seemed to present lower quality aesthetic results. This pilot study may be one of the first to perform 3D impressions of images from CT to visualize the musculature in Brazil and may become an additional tool for teaching.
ABSTRACT
Unclaimed corpses were for many years the supply of human material for the study of human anatomy. However, due to improved quality of life and technology, there has been the surround these. Faced with these circumstances, and the impossibility of total replacement of this material by others in training future professionals and the endless dissection technique, the Donation Voluntary Bodies for Anatomical Study is presented as an alternative to capture corpses or who wish to donate your body or part of it to research institutions and scientific study, without obtaining any pecuniary gain. Thus, the present study aimed to gather information about the knowledge and belief of the population of anatomists and freshmen, on the subject; obtain information on the importance of discipline and dissection for professional practice and reliability of the general population, and develop Donation Program Voluntary Bodies for Anatomical Study (pdvcea) for University of São Paulo (DA-ICB/USP). Regarding the importance of dissection for vocational training is considered, for the general population, such as reliability factor in professional medical surgeon, the possibility of donating Bodies is not unknown to the majority of the population studied, which do not necessarily set in potential donors. The pdvcea is created, institutionalized, but still in the process of acquiring gravesite tributes to the institution; dependent for its dissemination, clarification and placement in mass media, to decrease the time of drafting the seat of death, without financial loss to the relatives of the donors.
Los cadáveres no reclamados fueron durante muchos años la fuente de material humano para el estudio de la anatomía humana. Sin embargo, debido a la mejora de la calidad de vida y la tecnología, ha habido una disminución de éstos. Frente a estas circunstancias, y la imposibilidad de la total sustitución de este material por otros en la formación de futuros profesionales y de la técnica de la disección, la donación voluntaria de cuerpos para el estudio anatómico se presenta como una alternativa a los cadáveres no reclamados o quienes desean donar su cuerpo o parte de este a instituciones de investigación y estudio científico, sin obtener ningún beneficio pecuniario. Así, el presente estudio tuvo como objetivo reunir información sobre el conocimiento y la creencia que tiene los anatomistas y estudiantes de primer año, sobre el tema; De esta manera se pretende obtener información sobre la importancia de la disciplina y la disección para la práctica profesional y la confiabilidad de la población en general, y desarrollar el Programa de Donación Voluntaria de Cuerpos para Estudio Anatómico (pdvcea) para la Universidad de São Paulo (DA-ICB / USP). Respecto a la importancia de la disección para la formación profesional se considera, para la población en general, como el factor de fiabilidad en el profesional médico cirujano, la posibilidad de donar órganos no es desconocida para la mayoría de la población estudiada, que no necesariamente se establece en donantes potenciales. El pdvcea fue creado e institucionalizado, pero todavía está en proceso de adquirir recursos para la institución; dependiente para su difusión, aclaración y colocación en los medios de comunicación, para disminuir el tiempo de redacción de la causa de muerte, sin pérdida económica para los familiares de los donantes.
