BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray diagnostic apparatus,
In particular, it relates to an X-ray diagnostic apparatus having a spot shot mechanism.

[0002]

2. Description of the Related Art There are two types of spot shot mechanisms for an X-ray diagnostic apparatus, a so-called front loading type and a rear loading type.

In the front loading type, a feed magazine containing an X-ray film (raw film) for photographing and a take-up magazine containing an already photographed X-ray film are arranged below the bed, and the loading side of each magazine is set. It is provided in front of the bed, that is, on the side opposite the gantry.

On the other hand, in the rear loading type, a feed magazine and a take-up magazine are arranged on the back surface of the bed.

The front loading type has a high operability and is easy to use since the magazine can be loaded and unloaded in front of the bed. Furthermore, since there is no protruding portion on the back surface of the bed, the installation area can be small.

[0006]

However, since a space for loading and unloading the magazine must be secured in front of the bed, when performing medical procedures other than X-ray diagnosis, for example, ultrasonic diagnosis or catheter examination. However, there has been a problem that it is difficult to keep medical devices related to these devices near the bed.

Further, when the X-ray tube and the image intensifier are moved in the longitudinal direction of the bed, the stroke of the longitudinal movement is shortened by the width of the magazine, and as a result, the diagnostic area is narrowed. Was occurring.

In order to solve such a problem and secure a predetermined photographing area, the top of the bed may be moved longitudinally, but this is an extra burden on the patient and causes troubles in catheter examination and the like.

On the other hand, in the rear loading type, since the magazine is loaded and unloaded from the back of the bed, the problems of the front loading type do not occur, but the operability is poor and it is difficult to use. In addition, there is a problem that the installation area becomes large because the protruding portion is present on the back surface of the bed.

The present invention has been made in consideration of the above-mentioned circumstances, and it is possible to secure a predetermined imaging region without moving the top plate and to perform various medical procedures other than X-ray diagnosis in parallel with X-ray diagnosis. It is an object of the present invention to provide an X-ray diagnostic apparatus equipped with a spot shot mechanism that can be carried out as a whole and that can easily handle a magazine.

Further, in the X-ray diagnostic apparatus of the present invention, the predetermined size is a four-section (10 inches × 12 inches).

[0015]

In the X-ray diagnostic apparatus of the present invention, the first spot shot portion and the second spot shot portion can be freely selected according to the film size and the contents of inspection. That is, the first spot shot section is made by using a small size X-ray film that is relatively frequently used.
Radiographing is performed, and the second spot shot section mainly uses a large-format X-ray film that is relatively infrequently used.

In a general medical examination or the like, a small-sized X-ray film contained in the feed magazine of the first spot shot section is sent to the photographing area by the transport mechanism. After the shooting is finished, the taken X-ray film is collected in the take-up magazine by the transport mechanism.

Here, since the loading side of each magazine is in front of the bed, an X-ray technician or the like removes each magazine,
It can be installed easily.

When using a large-sized X-ray film such as a large-format or large-angle format, the large-size X-ray film is sent from the feed magazine of the second spot shot section to the photographing area by the transport mechanism. After the shooting is finished, the taken X-ray film is collected in the take-up magazine by the transport mechanism.

Here, since the loading side of each magazine is on the gantry side, that is, on the back of the bed, ultrasonic diagnosis, catheter examination, etc. are performed separately from the X-ray diagnosis, and medical devices related to them are placed in front of the bed. Even when the magazine is placed in the magazine, the magazine can be easily attached and detached with each medical device left as it is.

Further, when it is desired to carry out continuous photographing using a small size X-ray film, a magazine capable of accommodating the small size X-ray film is loaded in the second spot shot section and the first spot shot section and It is possible to alternately supply a small size X-ray film to the photographing region from the second spot shot section and continuously perform X-ray photographing in a short time.
