Embodiment Construction
[0023] The device structure and imaging method of the present invention are described in conjunction with the accompanying drawings.
[0024] The device structure of the present invention is as figure 1 Shown:
[0025] The detector 1 is placed on the detector base 2, and a long pole 3 is installed at a distance of 50 cm from the detector. The other end of the long pole 3 is equipped with a crossbar 4, and the X-ray source 5 is fixed on the crossbar 4. The ray source 5 is provided with collimating facilities to ensure that the X-rays emitted by the X-ray source 5 exit in the form of a single beam and face the detector 1 . And the cross bar 4 can slide on the long bar 3, thereby adjusting the distance from the X-ray source to the detector. During the sliding process of the crossbar, the X-ray source is always kept facing the detector, and the adjustable distance from the X-ray source to the detector ranges from 300mm to 700mm. A Z-direction stepping motor 6 is fixed on the l...
