Another object of the invention is to provide a device for the distant viewing of radioscopic images in which the observer may be stationed in an undarkened room so that the time period otherwise necessary for the adaptation of the eyes of the observer to the dark room“ is eliminated, and the observation of the position of the patient and all his movements is facilitated. Still another object of the invention is to provide an arrangement for the distant viewing of ,radioscopic images, obtained on a ?uorescent screen, from a patient placed in contact with a radiologic table regardless of whether such table 6 10 15 20 ‘ 1 ‘Referring now to the drawings, and first to Figs. 1 to 4, I is an X-ray tube mounted on the rear of the radiologic table 2, which latter is piv oted in a frame 2a and in Figs. 1 to 4 is adjusted to a vertical position. A ?uorescent screen 3 is mounted at a distance in front and parallel to the radiologic table 2 and connected with the lat ter by lateral brackets to. A telescopic frame 1 extends forwardly from the ?uorescent screen 3 at substantially right angles to the latter and Supports an cXpa’nding bellows t3- A mirror bOX 5 is mounted on the front end .of the bellows 4 and contains two lenses 6d disposed at right . angles to one another and a mirror to disposed at an angle of 45° to the ‘Optical aXiS 0f the dc vice so as to de?ect light rays entering the box 5 through One Of the 1611865 5a at all angle of 99°, whereupon said light rays are emitted through the Second 18115 6a- v ' " and ?uorescent screen are placed in a horizontal The entire X-I‘aY equipment, including the position or in a vertical position_ I radiologic table, the X-ray tube, the ?uorescent A still further object of the invention is to screen, ‘the telescope frame, thebenows and the ‘provide an arrangement which permits of modi- 25 mirror bOX may be tilted ‘in the frame 2a and fying the size of the ?eld of radioscopic vision adjusted either to a position in which the radio on the ?uorescent screen in accordance with the logic table and ?uorescent screen extend in ver magnitude of the desired enlargement, depend- tit-‘1&1 planes and the telescope ‘frame and 1061 ing upon the organ of the patient to be observed so lows project horizon/tally (see Figs. 1 ‘and 2), 01' and diagnosed. to a position in which the radiologic table and These and other objects, which will appear ?uorescent screen are disposed in horizontal more clearly as the speci?cation proceeds, are planes and the telescope frame and bellows pro accomplished according to the present invention ject vertically upwardly from the ?uorescent by the arrangement and combination of elescreen (see Fig- 5) ments set forth in the following detailed descrip- 35 The telescope frame and bellows may be ex tion, defined in the appended claims and illustended to various lengths, the least extended po tratively exempli?ed by the accompanying sition being shown in full lines in Figs. 2 and 5, drawings in which, each of which shows two further extended posi Fig. 1 is an end View of the arrangement ac- 40 tions in broken lines. cording to the invention With the radiologic table 8 is an upright lead sheet covered partition wall and ?uorescent screen in o vertical position. disposed in a plane parallel to the optical axis of Figs. 2 and 3 are separate side views respecthe X-ray equipment and provided with a hori tively 0f the X—1‘ay equipment including the zontal slot l3, the longitudinal edges of which radiologic table, X-ray tube, the ?uorescent 4c are equidistantly spaced from the horizontal screen and a mirror box connected to the ?uorescent screen by means of a bellows; and of the plane containing the optical axis of the Y-ray apparatus when the latter assumes the position protective Wall in which part of the viewing in which its optical axis extends horizontal (see equipment is slidably supported.
