Abstract

In an era when it was not possible to achieve quality X-rays with short exposure times, the need to obtain chest images without movement led the French doctor Emré Hyacinthe Guilleminot to construct a machine that repeatedly emitted X-rays only when desired during the respiratory cycle. His aim was to create a satisfactory radiograph from multiple short bursts performed at the moment of inhalation or exhalation, based on Charles Bouchard's research on heart disease. He extended his idea to radiography of the heart, creating a system that enabled images to be obtained disassociating the phases of heartbeat. This article seeks to explain the basic functioning of these mechanisms, and to recover previous research papers that led to their creation. We will also retrieve biographical and personal data of the two people involved – one directly, the other indirectly – in these novel inventions.

Resumen

En una época en que no era posible conseguir radiografías de calidad con tiempos de exposición cortos, la necesidad de obtener imágenes del tórax sin movimiento llevó al médico francés Emré Hyacinthe Guilleminot a construir un aparato que disparase rayos X de manera repetida únicamente en el momento deseado del ciclo respiratorio. Su objetivo fue, partiendo de las investigaciones sobre patologías cardíacas de Charles Bouchard, componer una radiografía satisfactoria a partir de múltiples disparos cortos realizados en el mismo instante de la inspiración o la espiración. Extendió su idea a la radiografía del corazón, creando un sistema que permitía obtener imágenes disociando las fases del latido. El presente artículo pretende explicar el funcionamiento básico de aquellos mecanismos, así como recuperar los trabajos de investigación previos que motivaron su creación. También rescatará datos biográficos y personales de las dos figuras involucradas – directamente uno, indirectamente el otro – en aquellas novedosas invenciones.
