    • A radiographic apparatus detector and method therefore obtains an image having excellent recognition without the effect of body movement. A single composite image is generated by connecting strip images in the movement direction of a radiation emitter, which are extending in a direction orthogonal to an emitter movement direction. A flat panel detector (FPD) moves so that an incident radiation region in the FPD follows the shooting. A transmissive image with an improved visual recognition is obtained since shooting the strip image in the FPD is conducted by using an unused part.

    • To automate positioning operation of an X-ray tube so as to reduce the inspection time. Anatomical program selection means selects a surgery method/imaging object portion so that an imaging condition stored as an anatomical program in advance is called out and set in an X-ray generation device. Here, when an operation switch is pressed, control means moves drive means built in X-ray irradiation means parallel movement holding means and X-ray irradiation means rotation holding means so as to obtain the positional relationship between an X-ray tube and an FPD stored in correspondence with the anatomical program (such as SID and incident angle). The position of the FPD should be matched with the examinee. However, since the positional relationship between the X-ray tube and the FPD is almost constant in accordance with the surgery method/imaging object portion, it is possible to reduce the time required for positioning the X-ray tube by using this configuration.
    • 自动化X射线管的定位操作,以减少检查时间。 解剖程序选择装置选择手术方法/成像对象部分,使得在X射线产生装置中调出并设置作为解剖学程序预先存储的成像条件。 这里,当按下操作开关时,控制装置移动内置在X射线照射装置平行移动保持装置和X射线照射装置旋转保持装置中的驱动装置,以获得X射线管和FPD之间的位置关系 存储与解剖程序相对应(如SID和入射角)。 FPD的位置应与受检者相匹配。 然而,由于X射线管和FPD之间的位置关系根据手术方法/成像对象部分几乎是恒定的,所以可以通过使用这种配置来减少定位X射线管所需的时间。
