Abstract

Se proporcionan un dispositivo de adquisición de imágenes y un método de adquisición de imágenes capaz de adquirir los contornos internos y externos de un objeto medido con un alto grado de precisión. Un dispositivo 1 de adquisición de imágenes incluye: una primera fuente 10 de rayos X que aplica rayos X que tienen un primer tamaño de punto focal; un primer detector 20 que detecta rayos X aplicados desde la primera fuente 10 de rayos X y que han pasado a través de un objeto medido O; un primer medio 30 de generación de imágenes que genera una primera imagen de TC de rayos X sobre la base de los rayos X detectados por el primer detector 20; una segunda fuente 40 de rayos X que aplica rayos X que tienen un segundo tamaño de punto focal más pequeño que el primer tamaño de punto focal; un segundo detector 50 que detecta los rayos X aplicados desde la segunda fuente de rayos X y que han pasado a través del objeto medido O; un segundo medio 60 de generación de imágenes que genera una segunda imagen de TC de rayos X sobre la base de los rayos X detectados por el segundo detector 50; y un medio 70 de corrección de imágenes que corrige la primera imagen de TC de rayos X generada por los primeros medios 30 de generación de imágenes sobre la base de la segunda imagen de TC de rayos X generada por los segundos medios 60 de generación de imágenes.
