Abstract:
1. An apparatus for X-ray photography, comprising: a first X-ray source, having a light emitting end, wherein the light emitting end is provided with a block element, the first X-ray source generates an X-ray beam through the light emitting end, the block element is used for constraining a projection field of the X-ray beam, so that the X-ray beam has a first boundary at a central line of said projection field intersecting a sella turcica of an object, an anterior half of said X-ray beam is cast onto said object, the object has a reference center and an imageable area, and the block element is a shield block for shielding a posterior half of said X-ray beam posterior to said first boundary; a first driving device, used for driving the first X-ray source to rotate around the object within an angle range with the reference center of the object as a center, wherein, in the rotation process of the first X-ray source, the X-ray beam is projected onto the imageable area, and when the first X-ray source is located at a first position, the first boundary is a boundary of the imageable area; and an image detecting device, disposed at a side of the object and facing the first X-ray source, wherein after being cast onto the object, the X-ray beam is projected onto the image detecting device, thereby forming an image on the image detecting device.
