Detailed ways

The utility model will be further described below in conjunction with accompanying drawing. the

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of digital X-ray machine placement automatic recognition device comprises X-ray simulation host 1, X-ray simulation human 2 and control circuit; Frame 11, rotating frame 12, X-ray tube model 14, machine head 15, image intensifier model 18, point light source 16, camera 19 and scanning bed 17 constitute, rotating frame 12 is fixed on the fixed frame 11, machine The head 15 and the image intensifier model 18 are respectively connected and fixed on the upper end and the lower end of the rotating frame 12 by the frame arm 13, an X-ray tube model 14 is connected above the head 15, and a point light source 16 and a camera 19 are arranged inside the head 15 , the scanning bed 17 is overhead between the head 15 and the image intensifier model 18; the X-ray positioning simulator 2 is composed of various parts of the simulated human body; the computer system is mainly composed of a hardware system, a digital X-ray machine computer software system and image acquisition The X-ray simulation host 1 is electrically connected to the computer system, and the camera 19 inside the X-ray simulation host 1 communicates with the digital X-ray machine computer software system in real time through the image acquisition card. the
