“…The calibration of diagnostic and technological tools is a social and technical process in medicine and global health, involving tensions between standardization and localization. 3 Moreover, calibration is often analyzed from epistemological, socio-historical, and analytical perspectives, 4 but in the case of CAD technologies, through the adjustments to this calibration, another aspect emerges, a socio-political one. In the first part, we will shed some light on the results of our survey, showing how the calibration of CAD tools continues to be uncertain regarding the specificities of TB.…”

Computer-aided detection algorithms based on artificial intelligence are increasingly being tested and used as a means for detecting tuberculosis in countries where the epidemic is still present. Computer-aided detection tools are often presented as a global solution that can be deployed in all the geographical areas concerned by tuberculosis, but at the same time, they need to be adjusted and calibrated according to local populations’ characteristics. The aim of this article is to analyze the tensions between the standardization of computer-aided detection algorithms and their local adaptation and the political issues associated with these tensions. We undertook a qualitative analysis of practices associated with tuberculosis detection algorithms in different contexts, contrasting the perspectives of various stakeholders. Algorithms embed the promise of standardization through automation and the bypassing of variable human expertise such as that of radiologists, they are nonetheless objects of local practices that we have characterized as “tweaking.” This work of tweaking reveals how the technology is situated but also the many concerns of the users and workers (insertion in care, control over infrastructure, and political ownership). This should be better considered to truly make computer-aided detection innovative tools for tuberculosis management in global health.

En el sector industrial, la metrología permite respaldar la calidad de los procesos, debido a que, en todos estos, intervienen magnitudes físicas que influyen sobre cada etapa de estos y cuyos efectos se ven reflejados en la calidad del producto final. Estas magnitudes deben ser medidas para tomar acciones de control y garantizar que su efecto no será negativo en los requerimientos de los productos. Los instrumentos de medición, así como la confiabilidad metrológica de su calibración, a partir de uso de softwares y sistemas computarizados, se tornan grandes desafíos para la metrología industrial. En ese orden de ideas, el objetivo principal de este trabajo es explicitar la metodología para el diseño de un software que permita generar certificados de calibración en metrología térmica. El trabajo fue motivado debido a desafíos impuestos por Laboratorios Acreditados para optimizar sus procesos. La metodología adoptada, basada en la programación de algoritmos computacionales en un lenguaje C-Sharp (C#) posibilitó: (i) realizar un complejo análisis de incertidumbre (GUM); (ii) estimar la curva de calibración ajustada a partir de la teoría consagrada de los mínimos cuadrados ordinarios y (iii) validación a partir de datos experimentales realies. Los resultados consolidados permitieron concluir que el software desarrollado se encuentra alineado a las exigencias de la ISO/IEC 17025:2017, además de constituirse una herramienta eficaz para el aumento de la confiabilidad metrológica de los procesos industriales, contribuyendo así, al avance del conocimiento en la metrología.
