Next, the location when using present embodiment 1 described X line photographic attachment to carry out detected person's thoracic photography describes.When carrying out detected person's thoracic photography, in order to take bigger zone with lower amplification, SID is made as 1.8m～2m.With take chest beyond SID during the position compare about 1.1m, distance is relatively large.
When taking detected person's chest, at first as shown in Figure 1, move up and down drive division 4 by support slider 4a is moved to a direction, the height adjustment that the X line is subjected to picture portion 12 is near detected person's the chest locations.Afterwards, make support 6 to the rotation of b direction, support 6 is stopped on the approximate horizontal position by support rotary driving part 5.Under this position, be arranged on the X spool portion 10 of support 6 one ends and aperture portion 11, be subjected to picture portion 12 with the X line that is arranged on support 6 other ends, be configured in the lateral outside of main body case 1a relative.Thereby can not be subjected to apparatus main body 1 to be subjected to catch detected person's photography position at the X line as the image planes 12a center that is subjected to of portion 12 with influencing.
Then, operate near the photographic attachment operating portion 14 that is arranged on the apparatus main body 1 shown in Figure 3, as shown in Figure 5, the motor 7f by being provided with on the drive division 7 before and after the X spool makes the second support 6b move to the direction of leaving preset distance from the first support 6a.So, be subjected to picture portion 12, SID is adjusted into about 1.8m～2m by making X spool portion 10 leave the X line.
And, under this state, before making detected person 20 stand in the X line as shown in Figure 7 to be subjected to picture portion 12.Operation photographic attachment operating portion 14, moving up and down drive division 4 by support moves up and down slider 4a, so that the chest of detected body 20 correctly is subjected to mode between the picture portion 12 at X spool portion 10 and X line, the X line is subjected to finely tune as the height of portion 12, and carries out the position adjustment of the adjustment, light filter etc. in the roentgen radiation x visual field that the switching by the aperture blades that is built in aperture portion 11 causes.
And, because having adjusted the X line of height is subjected to be positioned near the apparatus main body 1 as portion 12, the X line is subjected to be roughly same plane as the front of the photographic plane of portion 12 and main body case 1a, therefore is subjected between the picture portion 12 in X spool portion 10 and X line, has guaranteed not to be subjected to the competent space of main body case 1a restriction.And X spool portion 10 and aperture portion 11 are subjected to picture portion 12 relative with the X line on fully away from the position of apparatus main body 1.Therefore, detected body 20 can easily stand in X spool portion 10 and the X line is subjected between the picture portion 12, and seldom can feel constriction because of main body case 1a in photography.
As mentioned above, after being ready to complete of photography, operation photographic attachment operating portion 14 begins to carry out the photography of X line.See through detected body 20 and shine the X line and be subjected to the X line on the image planes 12a of being subjected to, be subjected to read by the X line as portion 12 as the X line image as portion 12.Afterwards, this image is handled by image processing part 17, and is presented in real time in the image-display units 18.In addition, this image is recorded in the not shown record portion, and X line generating unit 16 by not shown hospital in network when being connected to the terminal that the doctor uses, not only the location of X line generating unit 16 can be carried out, and the setting of the condition, the roentgen radiation x visual field etc. of X line can be carried out corresponding to radiographing order from the doctor.
And by the order from photographic attachment operating portion 14, control simultaneously is positioned at the rotary driving part 9 that support rotary driving part 5 on the same axle and X line are subjected to picture portion, and X line image receiving means 12 is rotated synchronously to the direction identical with the direction of rotation b of support 6.In other words, can make X spool portion and X line be subjected to the relative angle of picture portion to keep constant.So, can make X spool portion 10 with support 6 rotations, from the detected body 20 of oblique shooting keeping under the parallel state of detected body 20 and X line image receiving means 12.
On the other hand, Fig. 8 represents to use the waist side of special-purpose 21 pairs of detected bodies 20 of travelling carriage to carry out the situation that the X line is photographed.Below its action is described.
When the waist side of detected body 20 being carried out the photography of X line, at first operate photographic attachment operating portion 14, the slider 4a that support is moved up and down drive division 4 moves up and down suitable height and position.Make the clockwise direction rotation of support 6 by support rotary driving part 4 afterwards, make it state into approximate horizontal to the b direction.Afterwards, make detected body 20, move to X spool portion 10 and X line as shown in Figure 8 and be subjected between the picture portion 12 with the travelling carriage 21 that ventral decubitus or supine position carry.
At this moment, support 6 is center rotation with rotating shaft 5a, and the X line that therefore is installed in support 6 top ends is subjected to change hardly as the position of the horizontal direction of portion.Therefore the X line can't obviously be given prominence to from the positive of main body case 1a by picture portion 12.Even support 6 is positioned at the state of approximate horizontal, between being subjected to as portion 12, X spool portion 10 and X line also can guarantee not to be subjected to the sufficient space of main body case 1a restriction, by this space, travelling carriage 21 is easily moved between X spool portion 10 and the X line image receiving means 12, therefore the problem that also can avoid this moment travelling carriage 21 and main body case 1a to collide.
As shown in Figure 8, the mobile end of travelling carriage 21, the waist of detected body 20 after between X spool portion 10 and the X line image receiving means 12, operation photographic attachment operating portion 14.Photographic attachment moving part 14 moves up and down the height that drive division 4 is adjusted support 6 by support, so that the waist of detected body 20 correctly is subjected between the picture portion 12 in X spool portion 10 and X line.Meanwhile the SID between X spool portion 10 and the X line image receiving means 12 for example is adjusted into 1.1m.When taking the waist side, at first move up and down the height that drive division 4 is adjusted support 6 by support.And, by support rotary driving part 5 support 6 is remained the state of approximate horizontal, be subjected under the state of picture portion 12 relative configurations with the X line in X spool portion 10, telescope support 6 is subjected to X spool portion 10 and X line to be adjusted into distance arbitrarily as the SID between the portion 12.So, when carrying out the photography at position beyond the chest, also can position simply with an X line photographic attachment.
And, during the photography at position, have the situation of detected body 20 beyond the chest for ventral decubitus or supine position state.Support 6 is essentially the word of falling U shape or shape similar with it, when support 6 is made as level, is subjected to the support 6 of the part between the picture portion 12 at X spool portion 10 and X line, can be configured to from X spool portion 10 and X line to be subjected to project upwards as the upper surface of portion 12.Even therefore make X spool portion 10 and X line be subjected to picture portion 12 relative on the position relative with detected body 20 waists, the central part of support 6 can not contact detected body 20 yet.
