Radiological Society of North America (RSNA) 3D printing Special Interest Group (SIG): Guidelines for medical 3D printing and appropriateness for clinical scenarios

Este número da revista Cadernos de Estudos Sociais estava em organização quando fomos colhidos pela morte do sociólogo Ernesto Laclau. Seu falecimento em 13 de abril de 2014 surpreendeu a todos, e particularmente ao editor Joanildo Burity, que foi seu orientando de doutorado na University of Essex, Inglaterra, e que recentemente o trouxe à Fundação Joaquim Nabuco para uma palestra, permitindo que muitos pudessem dialogar com um dos grandes intelectuais latinoamericanos contemporâneos. Assim, buscamos fazer uma homenagem ao sociólogo argentino publicando uma entrevista inédita concedida durante a sua passagem pelo Recife, em 2013, encerrando essa revista com uma sessão especial sobre a sua trajetória

A man from San Juan: facial approximation within anthropology

Dentro de la antropología y la identificación forense, la aproximación facial (también conocida como "reconstrucción facial") se presenta frecuentemente como un hecho consumado, con evidencia mínima de las investigaciones y los métodos usados para alcanzar los resultados. Este trabajo presenta un panorama detallado de la investigación y los métodos usados para realizar una aproximación facial grafica en 2D de un hombre prehistórico del valle de Jachal, provincia de San Juan, Argentina. Se entiende que corresponde a un miembro del extinto grupo Huarpe. El cráneo del individuo muestra numerosos rasgos morfológicos que son consistentes con lo que se conoce acerca de este grupo de agricultores tempranos americanos. Debido a que muchos de los métodos utilizados en esta reconstrucción facial aun no han sido verificados y aquellos que han sido debidamente probados se basan en promedios estadísticos de la variación humana, los resultados presentados deben ser vistos como indicativos de la posible apariencia facial del individuo dado el nivel actual de conocimiento, más que como un resultado definitivo.Within both anthropology and forensic identification, a facial approximation (also known as "facial reconstruction") is often presented as an accomplished fact, with minimal, or no evidence of the research and methods used to achieve the result. This paper presents a detailed overview of the research and methods used for a 2D computer graphic facial approximation of a prehistoric man unearthed in the Jachal Valley, San Juan Province, Argentina. Understood to be a member of the extinct Huarpe, this individual's skull displays many of the morphological features that are consistent with what is known about this group of early Amerindian farmers. Because many of the recommended methods that inform this facial approximation have yet to be verified, and those that have been appropriately tested are based on statistical averages of human variation, the results need to be viewed as indicative of this individual's possible facial appearance using current levels of knowledge, rather than as a definitive result.Asociación de Antropología Biológica de la República Argentin

Radiological Society of North America (RSNA) 3D printing Special Interest Group (SIG): guidelines for medical 3D printing and appropriateness for clinical scenarios

Abstract Medical three-dimensional (3D) printing has expanded dramatically over the past three decades with growth in both facility adoption and the variety of medical applications. Consideration for each step required to create accurate 3D printed models from medical imaging data impacts patient care and management. In this paper, a writing group representing the Radiological Society of North America Special Interest Group on 3D Printing (SIG) provides recommendations that have been vetted and voted on by the SIG active membership. This body of work includes appropriate clinical use of anatomic models 3D printed for diagnostic use in the care of patients with specific medical conditions. The recommendations provide guidance for approaches and tools in medical 3D printing, from image acquisition, segmentation of the desired anatomy intended for 3D printing, creation of a 3D-printable model, and post-processing of 3D printed anatomic models for patient care.https://deepblue.lib.umich.edu/bitstream/2027.42/146524/1/41205_2018_Article_30.pd
