    • An apparatus for spatial modulation of an x-ray beam has a number of planar attenuation elements for x-ray radiation that are disposed in a grid on a carrier and can be pivoted or tilted by a piezoelectric actuator, independently of one another, between at least two positions. One or more sensors with which a piezoelectrically-caused length and/or width and/or position change of the piezoelectrically influenced regions can be detected, are arranged on piezoelectrically influenced regions of the attenuation elements or the actuators. A significant dose reduction and/or dynamic adjustment thereof can be achieved with the apparatus by image adaptation in many areas of x-ray imaging, since a precise determination of the position of each attenuation element in real time is enabled.
    • 用于x射线束的空间调制的装置具有多个用于x射线辐射的平面衰减元件,其被布置在载体上的栅格中,并且可以彼此独立地由压电致动器枢转或倾斜,处于 至少两个职位。 能够检测压电影响区域的压电引起的长度和/或宽度和/或位置变化的一个或多个传感器被布置在衰减元件或致动器的压电影响区域上。 由于能够实时精确地确定每个衰减元件的位置,所以可以通过在x射线成像的许多区域中的图像适应来实现该设备的显着剂量减小和/或动态调整。
