Description

X-ray system

Technical field

The present invention relates to x-ray system, the special multi-functional X-ray system using suspention bulb.

Background technology

X-ray system has two kinds usually, and a kind of is adopt single bulb to coordinate the simple and easy sick bed of breast photograph shelf or function without spin to carry out digital radiography (DR) system of making film.Another kind is perspective general x-ray imaging (fluoro) system adopting rotatable sick bed and install bulb based on this sick bed lathe bed body.But this examinating couch does not have elevating function usually, patient's bunk bed difficulty, due to bulb and examinating couch relative position comparatively fixing, the full source of gamut that also limit Image chain is at a distance of the application of (SID).

Summary of the invention

The object of this invention is to provide a kind of x-ray system, it can provide the X ray image of illuminated object diverse location and different angles, and easy to operate, and structure is simple, stable.

The invention provides x-ray system, comprise the examinating couch and that a suspention bulb, can launching X-ray can carry x-ray bombardment object and be installed on examinating couch and the video receiver of X ray image can be recorded.Examinating couch comprises a bed body and four can the support bar of supporting bed body, and each support bar telescopically is articulated with a body, and four end points of any two adjacent supports bars can form an isosceles trapezoid, and two support bars are two waists wherein.

In a kind of exemplary embodiment of x-ray system, support bar is the extensible member driven by hydraulic pressure or linear electric motors, and it can be connected by universal joint articulated with bed body.

Alternatively, described support bar can be connected by universal joint articulated with described bed body.

In the another kind of exemplary embodiment of x-ray system, video receiver is flat receiver, and the part of the bed body installation flat receiver of examinating couch is provided with slide rail, and flat receiver can move along slide rail, to adapt to the irradiation position suspending bulb in midair.

Alternatively, described slide rail is line slide rail or decussation slide rail.If line slide rail is longitudinally arranged, so video receiver can vertically move along line slide rail; If line slide rail horizontally set, so video receiver can along line slide rail at transverse shifting.If adopt decussation slide rail, so video receiver can move along this decussation slide rail at vertical and horizontal.

Alternatively, wherein said video receiver can upwards overturn an angle in one end of slide rail, thus can meet various irradiation position and the angle of irradiation object.

Detailed description of the invention

In order to the technical characteristic to invention, object and effect have understanding clearly, now contrast accompanying drawing and the specific embodiment of the present invention is described, accompanying drawing only understands the present invention for helping, not the practical structures of representative products and actual proportions, and label identical in the various figures represents identical part.

In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, embodiment is interpreted as a kind of preferred or have more the technical scheme of advantage.In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".

As depicted in figs. 1 and 2, x-ray system comprises suspention bulb 10, examinating couch 20 and a video receiver 30.Suspend bulb 10 in midair in order to launch X-ray, for the illuminated object 40 on examinating couch 20 carries out fluoro imaging and SID film making.Video receiver 30 is installed on examinating couch 20, in order to record X ray image.

Examinating couch 20 can carry x-ray bombardment object 40, examinating couch 20 comprises a bed body 22 and four can the support bar 24 of supporting bed body 22, support bar 24 telescopically is articulated with a body 22, as shown in the figure, four end points of any two adjacent supports bars 24 can form an isosceles trapezoid, and two support bars 24 are two waists wherein.This trapezoidal climbing structure of support bar, can ensure planar stability and the bed body space stability of adjacent two support bars.Those skilled in the art are to be understood that, four end points of said any two adjacent supports bars 24 can form an isosceles trapezoid above, be not that four end points limiting any two adjacent supports bars 24 always form an isosceles trapezoid, and be only define their one of them states.

In addition, the bed body 22 of examinating couch 20 can be longer than the bed body of traditional examinating couch, thus meet the scanning space needed for RAD film making.

In a kind of exemplary embodiment of x-ray system, support bar 24 is the extensible member driven by hydraulic pressure or linear electric motors, and it can be connected by universal joint articulated with bed body 22.Support member can elongate or shorten with under the effect of universal joint flexible simultaneously, and the entirety realizing examinating couch raises or declines, to facilitate the upper and lower examinating couch of illuminated object.As shown in Figure 3, after four support bars 24 shorten simultaneously, the position in figure shown in solid line is adjusted in bed body 22 position shown in dotted line from figure of examinating couch 20.

When needs irradiate different piece, each support bar 24 can also adjust respectively as Fig. 4 or Fig. 5, make a body 22 along the vertical or horizontal inclination of illuminated object 40, the position of now adjustment suspention bulb 10 and angle, make the irradiated site of suspention bulb 10 and illuminated object 40 and video receiver 30 adapt.Fig. 4 and Fig. 5 only schematically illustrates two diverse locations of examinating couch, in actual use, examinating couch can adjust position according to different needs, substantially can the roll, pitching etc. of actual illuminated object, commonly uses and special attitude pendulum position to realize stomach and intestine machine.

In the another kind of exemplary embodiment of x-ray system, video receiver 30 is flat receiver, and the part of the bed body 22 of examinating couch 20 being installed flat receiver is provided with slide rail.This slide rail can be line slide rail, and as shown in Figure 6, flat receiver can move along described slide rail, as moved to the solid line position in figure from the dotted line position in Fig. 6, can expand the image receiving area of x-ray system like this.Although illustrate only video receiver 30 vertically moving along illuminated object 40 in Fig. 6, it will be understood by those skilled in the art that video receiver 30 also can along the transverse shifting of illuminated object 40.This slide rail can also be decussation slide rail, and so video receiver 30 can move along this decussation slide rail at vertical and horizontal.

As shown in Figure 7, in another exemplary embodiment of x-ray system, the slide rail place that video receiver 30 not only can install flat receiver on bed body 22 moves, video receiver 30 upwards can also flip an angle in one end of slide rail, and make it and suspend bulb 10 in midair and cooperatively interact, meeting various irradiation position and the angle of illuminated object 40.

Be to be understood that, although this description describes according to each embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.

A series of detailed description listed is above only illustrating for possible embodiments of the present invention; they are also not used to limit the scope of the invention; allly do not depart from the skill of the present invention equivalent embodiments done of spirit or change; as the combination of feature, segmentation or repetition, all should be included within protection scope of the present invention.
