Provided is a radiographic imaging device wherein a treatment tool such as forceps can be correctly positioned, under a transparent image, at a prescribed section of a lesion or similar that was detected using an observation tool such as an EBUS inserted into a subject, said observation tool having been removed in said transparent image. This radiographic imaging device comprises: a radiation source that irradiates a subject with radiation； a radiation detector that detects radiation passing through the subject； and a data processing unit that generates a transparent image of the subject on the basis of the quantity of radiation detected by the radiation detector, wherein the radiographic imaging device is characterized by further comprising a characteristic section extraction unit and a display processing unit. The characteristic section extraction unit extracts the location, in a first image, of a characteristic section of an observation tool that detects a prescribed section, said first image being a transparent image from when the observation tool has been inserted into the subject. The display processing unit displays an object in a second image on the basis of the location extracted by the characteristic section extraction unit, said object being referenced when positioning a treatment tool that is inserted into the subject, and said second image being a transparent image from when the observation tool has been removed from the subject.L'invention concerne un dispositif d'imagerie radiographique dans lequel un outil de traitement tel qu'une pince peut être correctement positionné, sous une image transparente, au niveau d'une section prescrite d'une lésion ou similaire qui a été détectée à l'aide d'un outil d'observation tel qu'une sonde d'EBUS insérée dans un sujet, ledit outil d'observation ayant été retiré dans ladite image transparente. Le dispositif d'imagerie radiographique comprend : une source de rayonnement qui expose un sujet à un rayonnement ； un dét
