摘要：
An extraoral system for obtaining dental images by X-rays, to obtain a partial or partial 3D CT image of a region of interest of an object, the system comprising: a) a source (2102) of X-rays for exposure to X-rays an object, so that images of the object can be obtained during exposure, b) a device (2101) for obtaining X-ray images suitable for producing multiple irradiated image frames during at least part of the exposure； c) a manipulator (2105) to move the imaging device and the X-ray source along a path between plural positions corresponding to plural image frames irradiated during exposure, the manipulator allowing movement of both the source X-ray as the imaging device by selective translation and selective rotation around at least one axis (2106) of rotation located between a focal point of the X-ray source and the device for X-ray imaging； characterized in that it additionally comprises d) an additional manipulator (2103) for moving or rotating the imaging device for at least part of the exposure with respect to the axis of rotation, and e) an additional manipulator (2104) for moving or rotating the X-ray source for at least part of the exposure with respect to the axis of rotation.Un sistema extraoral para obtención de imágenes dentales por rayos X, para obtener una imagen de TC parcial o 3D parcial de una región de interés de un objeto, comprendiendo el sistema: a) una fuente (2102) de rayos X para exponer a rayos X un objeto, de modo que se puedan obtener imágenes del objeto durante la exposición, b) un dispositivo (2101) para obtención de imágenes por rayos X adecuado para producir múltiples fotogramas de imagen irradiados durante al menos parte de la exposición； c) un manipulador (2105) para mover el dispositivo de obtención de imágenes y la fuente de rayos X a lo largo de una trayectoria entre posiciones plurales correspondientes a fotogramas plurales de imagen irradiados durante la exposición, permitiendo el manipulador el movimiento tanto de la fuent
