    • A method of determining the magnification of an x-ray image of an object, or a portion of an object, comprising: (i) providing to the object to be x-rayed; (ii) providing a first posterior x-ray marker having pre-determined dimension; (iii) providing anteriorly to the object to be x-rayed, a second x-ray marker having predetermined dimensions; (iv) recording an x-ray image of the object and the first and second x-ray markers; and (v) comprising a dimension of the first x-ray marker recorded on the image, a dimension of the second x-ray marker recorded on the image to a pre-determined value for the object x-rayed, to estimate the magnification of the image of the object.
    • 一种确定物体或物体的一部分的X射线图像的放大倍数的方法,包括:(i)提供待被X射线的物体; (ii)提供具有预定尺寸的第一后置x射线标记; (iii)向前放置待被X射线的物体,具有预定尺寸的第二x射线标记; (iv)记录物体和第一和第二X射线标记物的X射线图像; 以及(v)包括记录在图像上的第一x射线标记的尺寸,记录在图像上的第二x射线标记的尺寸为x射线物体的预定值,以估计 对象的图像。

    • Methods, devices, and kits for determining the magnification of an x-ray image of an object, or a portion of an object are described. An exemplary method comprises the steps of providing an object to be x-rayed, providing a first posterior x-ray marker having a pre-determined dimension, providing anteriorly to the object to be x-rayed, a second x-ray marker having predetermined dimensions, recording an x-ray image of the object, the first posterior x-ray marker, and second x-ray markers, and comparing a dimension of the first posterior x-ray marker recorded on the x-ray image, and a dimension of the second x-ray marker recorded on the image to a pre-determined value for the object x-rayed, to estimate a magnification of the x-ray image of the object.
    • 描述用于确定物体的X射线图像或物体的一部分的放大率的方法,装置和工具包。 一种示例性方法包括以下步骤:提供要被X射线的物体,提供具有预定尺寸的第一后X线标记,在待被X射线的物体的前方提供;具有预定的第二X射线标记 记录物体的X射线图像,第一后X射线标记物和第二X射线标记物,以及比较记录在x射线图像上的第一后X光标记的尺寸和尺寸 将记录在图像上的第二X射线标记作为x射线物体的预定值来估计物体的x射线图像的放大倍率。
