[0029] refer to figure 1 , the X-ray imaging system 10 according to the first embodiment of the present invention is a portable system suitable for use at the bedside of home care patients or in emergency or natural disaster situations. The X-ray imaging system 10 is composed of an X-ray generator 11, an electronic cassette 12, a holding arm 13, a notebook PC (hereinafter abbreviated as PC) 14, a control device 15, and a cable 16 for connecting all the above components.
[0030] The X-ray generator 11, electronic cassette 12, holding arm 13, PC 14 and control device 15 are transported separately to the bedside or emergency. At the target location, by connecting cables 16 and the like, the components are easily assembled into an X-ray imaging system 10, ready for X-ray imaging.
[0031] The X-ray generator 11 includes an X-ray source 17 , a high voltage generator 18 for supplying high voltage to the X-ray source 17 , and a radiation switch 19 . The X-ray source 17 is constitu...
no. 2 approach
[0072] In the first embodiment, the fitting portion 26 a of the base stay 26 is fitted in the opening 24 a of the handle 24 of the electronic cassette 12 to integrate the holding arm 13 with the electronic cassette 12 . However, if Figure 4As shown in He 5, the base support 26 may be provided with a tripod to provide the X-ray source 17 separately from the electronic cassette 12. In this case, contrary to the first embodiment, the electronic cassette 12 and the X-ray source 17 are not integrated by the holding arm 13 . Therefore, the holding arm 51 and the electronic cassette 12 are respectively provided with levels 52 and 53 and level adjusters 54 and 55 so that the moving plane of the X-ray source 17 is parallel to the incident surface 12 a of the electronic cassette 12 . Note that in each of the following embodiments, the same reference numerals as those of the first embodiment will denote the same or similar components as those of the first embodiment, and references to ...
no. 3 approach
[0076] Such as Figure 6 and 7 As shown, the X-ray imaging system 10 according to this embodiment is provided with a rotating arm 60 capable of rotating above the center of the incident plane 12a of the electronic cassette 12 at an angle of 180° around a vertical line passing through the center of the incident surface 12a. . At this time, if Figure 7 As shown, the laser pointer 61 is provided on the rotating arm 60 at a position in the center line of rotation CL. The position of the arm body 25 is determined so that the point pointed by the pointer 61 coincides with the center of the incident surface 12a. Base struts can be as in figure 1 of the assembly type shown, or as Figure 4 The type of tripod shown. Note that an adapter type base post is convenient for positioning because all the operator has to do is fit the base post into the opening of the handle.
[0077] The X-ray source 17 is connected to a swivel arm 60 via a tilt mechanism 62 . The pivot of the pivot a...
