    • In a construction having a radiation tube in an envelope filled with an insulating liquid, a radiation generating apparatus which realizes a miniaturization of the apparatus, an improvement of a withstanding voltage between the envelope and the radiation tube, and a decrease in attenuation amount of the radiation and a radiation imaging apparatus using the radiation generating apparatus are provided. The radiation generating apparatus has an envelope 12 having a first window 27 for transmitting the radiation, a radiation tube 14 enclosed in the envelope 12 and having a second window 19 for transmitting the radiation at a position in opposition to the first window 27, and an insulating liquid 13 filled between the envelope 12 and the radiation tube 14. A solid-state insulating member 28 is placed between the first window 27 and its periphery and the second window 19 and its periphery.
    • 在具有填充有绝缘液体的外壳中的放射管的结构中,实现设备小型化,辐射管外壳和辐射管之间耐受电压提高的辐射发生装置,以及 提供了使用该辐射发生装置的放射线和放射线成像装置。 辐射发生装置具有外壳12,其具有用于透射辐射的第一窗口27,封装在外壳12中的辐射管14,并具有用于在与第一窗口27相对的位置处传送辐射的第二窗口19, 绝缘液体13填充在封套12和辐射管14之间。固态绝缘构件28被放置在第一窗口27及其周边与第二窗口19及其周边之间。
