摘要： A shielding means for an X-ray machine or the like comprised of a base plate which removably receives shielding members masking out selective portions of the base plate to control the passage of X-rays therethrough. The shielding members are of various types and are provided with adjustable and removable securing means to position the shields on the base plate. Removable mounting means position and maintain the shielding means on the X-ray machine.

摘要： A shielding means for an x-ray machine comprised of a base plate which removably receives overlays masking out selective portions of the base plate to control the passage of the x-rays therethrough. The overlays are generally identical and provided with co-operating removable securing means to permit the same to be stacked one on the other to vary the thickness thereof. Removable mounting rails position and maintain the shielding means on the x-ray machine.
摘要翻译： 一种用于X射线机的屏蔽装置，其包括基板，该基板可移除地接收覆盖基板的选择部分的覆盖层，以控制x射线通过其中。 覆盖层通常是相同的并且具有可配合的可移除固定装置，以允许它们彼此层叠以改变其厚度。 可移动的安装导轨将X光机上的屏蔽装置定位和保持。

摘要： A shielding or masking device for use in conjunction with an X-ray radiation generating source comprised of radiopaque material having a vertically oriented opening having a broader portion twice the width of the upper, narrower portion nearer its distal or lower end to block entirely or confine radiation dosage to a specific area of a subject under observation or inspection and to prevent unnecessary and excessive radiation dosages to the subject during full spine radiographs.
摘要翻译： 用于与X射线辐射发生源结合使用的屏蔽或掩蔽装置，该X射线辐射发生源由不透射线材料组成，具有垂直定向的开口，该开口具有较宽部分的两倍宽的上部较窄部分，其较远部分的远端或下端完全阻挡 在观察或检查下对受试者的特定区域的辐射剂量，并且在全脊柱X光照片期间防止对受试者的不必要和过量的辐射剂量。
