X-ray examination device

An X-ray examination device (1) has an X-ray radiator (3) and an X-ray detector (4) for recording at least one X-ray image of a breast (8), and a compression unit (9) used for compression and fixationof the breast (8). A volume-variable and/or shape-variable positioning element (18) is disposed to act on the breast. The positioning element (18) has at least one chamber (30,31, and the like) and the volume-variability and/or shape-variability of the positioning element (18) can be effected by filling at least one chamber (30,31, and the like) of the positioning element (18) with a filling medium and/or by emptying at least one chamber (30,31, and the like) of the positioning element (18). 建议种X射线检查设备（1），具有X射线辐射器（3）和用于记录胸部（8）的至少个X射线图像的X射线探测器（4）；具有用于压迫和固定胸部（8）的压迫单元（9）其特征在于用于对胸部（8）进行作用的体积和/或形状可变的定位元件（18），其中定位元件（18）具有至少个腔室（30、31、...），并且其中能通过利用填充介质来填充定位元件（18）的至少个腔室（30、31、...）和/或通过排空定位元件（18）的至少个腔室（30、31、...）来引起定位元件（18）的体积和/或形状可变性。
