TRANSMISSION TYPE RADIATION GENERATING SOURCE AND RADIOGRAPHY APPARATUS INCLUDING SAME |
摘要 |
A transmission type radiation generating device includes an electron emitting source; a substrate that transmits radiation; a target provided on a surface of the substrate facing the electron emitting source and configured to generate radiation when electrons emitted from the electron emitting source are applied thereto; a shield member having a radiation passage that allows the radiation transmitted through the substrate to pass therethrough, the shield member being connected to the substrate and including at least a forward shield portion that protrudes in a direction away from the electron emitting source with respect to the target; and an insulating fluid in contact with the forward shield portion. The shield member includes a low-melting-point metal or a low-melting point alloy provided at least in the forward shield portion. |
