Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray radiographing apparatus for radiographing a subject for medical diagnosis.

[0002]

2. Description of the Related Art A conventional general X-ray radiographing apparatus is constructed as shown in FIG. 3, and an X-ray tube 3 having an irradiation field diaphragm 2 is provided on a first support column 1, and an X-ray tube is provided. A box body 5 supported by the second support column 4 is arranged in the traveling direction of the X-ray emitted from the tube 3. The box 5 is provided with a photographing unit 6 for sequentially holding the film in a photographing state from the X-ray tube 3 side, and supply magazines 7 and 8 for individually accommodating unphotographed films of different sizes. The magazine 7 contains, for example, large-angle film, and the other supply magazine 8 contains, for example, half-cut film. Further, an identification information imprinting section 10 is provided on the upper part of the box body 5 so that the identification information of the subject S is imprinted on the film.

At the time of photographing, a film corresponding to the body shape of the subject S is selected from the supply magazine 7 or 8 and conveyed to the photographing unit 6, and X is attached in close contact with a screen (not shown).
By exposing the X-ray from the X-ray tube 3, a chest X-ray image of the subject S is photographed on the film of the photographing unit 6.

At this time, a large-angle film is generally used for chest radiography, and a half-section film is used for a subject who is tall and has a large chest. The shooting method includes one-shot shooting and continuous shooting. Single shooting is used when there are relatively few subjects, and by pressing a size selection switch (not shown),
This is a method of supplying a film having a size corresponding to the subject S to the photographing unit 6. In this case, the following procedure is taken.

(1) The subject S is put in the imaging room. (2) The name of the subject S, the identification number, etc. are written on the identification card, and this card is set in the identification information imprinting section 10. (3) The height of the box 5 is adjusted according to the height of the subject S. (4) Adjust the height of the X-ray tube 3 according to the height of the box body 5. In the device called tube interlocking, the box 5
This procedure is unnecessary because the height of the X-ray tube 3 is automatically adjusted simply by adjusting the movement of. (5) In order to prevent the subject S from being irradiated with unnecessary X-rays, the irradiation field diaphragm 2 is adjusted according to the size of the film. (6) A film selection switch (not shown) provided on the box body 5 is pressed to convey a film having a size suitable for the subject S from the supply magazine 7 or 8 to the photographing unit 6.

On the other hand, continuous photography is used when there are many examinees. In this case, a film having the same size as the film of the previous subject is automatically sent to the photographing unit 6, and the following procedure is taken.

(A) The subject S is put in the imaging room. (b) Enter the name, identification number, etc. of the subject on the identification card and set it on the identification information imprinting section 10. (c) The height of the box 5 is adjusted according to the height of the subject S. (d) Adjust the height of the X-ray tube 3 according to the height of the box 5. (e) Adjust the irradiation field diaphragm 2 according to the size of the film. (f) Check if the size of the film already sent to the shooting unit 6 is appropriate. If the size is not appropriate, the film that has already been sent is collected in the receive magazine 9, and then the film of the appropriate size is sent to the photographing section 6 from another supply magazine 8 by pressing a film selection switch (not shown).

Although the height of the box 5 and the X-ray tube 3 are adjusted according to the height of the subject S in the above-mentioned procedure, the heights of the box 5 and the X-ray tube 3 are fixed. Then, the subject S may be adjusted by moving the subject S by an elevator.

[0009]

However, in the above-mentioned conventional example, it is necessary to set the photographing condition according to the subject S when photographing, which complicates the operation and requires a long time to set the photographing condition. There is a problem.

Further, since films of the same size are sent to the shooting unit 6 in continuous shooting, if the film size is not appropriate, the film already sent to the shooting unit 6 is collected in the receive magazine 9 and a new size is newly added. However, there is a problem that the original film is wasted because the original film has to be sent to the photographing unit 6.

If the size of the film sent to the photographing section 6 is large, the irradiation field diaphragm 2 must be narrowed so that unnecessary X-rays do not hit the subject S, which is troublesome and Since a large-sized film is used for the subject S, there is a problem that it becomes uneconomical. On the other hand, in order to prevent the film from being wasted, it is sufficient to repeat shooting one image, but in this case, there is a problem that it takes a long time to shoot one person.

An object of the present invention is to solve the above-mentioned problems and to provide an X-ray imaging apparatus capable of imaging a subject in a short time using a film having an optimum size.
