In a previous issue of this journal, we published a report entitled "Creation of Stereo-paired Bone Anatomical Charts Using Human Bone Specimens for Radiation Education" To understand how the bone specimen is visualized as an X-ray image, we newly created a bone specimen stereo-paired X-ray anatomical chart by adding the X-ray images of the same bone specimen. When a bone is X-rayed, the surface structure and internal structure of the bone are visualized as a composite image of the difference in X-ray absorption, and each bone becomes a unique X-ray image. Therefore, we took stereo-paired X-ray images of the bone specimens by the same method as the stereo-paired anatomical chart of the bone specimens. Then, we arranged the stereo-paired X-ray images and surface images of the same bone specimen in the one sheet to be readily compared. Similar to the previous bone specimen anatomical charts, these data of X-ray image anatomical chart were also made into an electronic file, so that we can do the three-dimensional observation of bone X-ray images even at the place of radiological examination or at home through electronic media. Until now, none of the specialized anatomy books and pictorial books are available for stereoscopic viewing of bone specimens and bone X-ray images. However, this stereo-paired X-ray image anatomical chart enabled us to learn accurate three-dimensionalization of bones by comparing the bone surface morphology and bone X-ray images.
在本刊的上一期中，我们发表了一篇题为《利用人体骨骼标本制作立体配对骨解剖图用于放射教育》的报告。为了解骨骼标本如何呈现为X射线图像，我们通过添加同一骨骼标本的X射线图像，新制作了一张骨骼标本立体配对X射线解剖图。当对骨骼进行X射线检查时，骨骼的表面结构和内部结构会呈现为X射线吸收差异的合成图像，每块骨骼都形成独特的X射线图像。因此，我们采用与骨骼标本立体配对解剖图相同的方法，对骨骼标本进行立体配对X射线成像。然后，我们将同一骨骼标本的立体配对X射线图像和表面图像排列在同一张纸上，以便于比较。与之前的骨骼标本解剖图类似，这些X射线图像解剖图的数据也被制成电子文件，这样我们甚至可以在放射检查地点或家中通过电子媒体对骨骼X射线图像进行三维观察。到目前为止，尚无专门的解剖学书籍和图谱可用于对骨骼标本和骨骼X射线图像进行立体观察。然而，这张立体配对X射线图像解剖图使我们能够通过比较骨骼表面形态和骨骼X射线图像来准确了解骨骼的三维结构。
