Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention is used in the fields of X-ray imaging apparatuses and film carriers.

The present invention relates to an X-ray rapid photography apparatus used for X-ray fluoroscopic diagnosis.

(B) Conventional technology In the conventional classical intensifying screen-film type X-ray photography method, intensifying screens are arranged on the front and back surfaces of the X-ray film, and they are held in close contact with each other to make X-ray After photographing and X-ray photographing, the X-ray film is developed, and it is diagnosed by looking at this. On the other hand, a new X-ray imaging method has been developed in which X-ray imaging is performed using a stimulable phosphor (Imazing Plate or IP). This new method uses the IP as an X-ray detector, reads the X-ray image data from the IP after X-ray imaging, performs image processing, displays it on a CRT monitor, or images it on a recording film for diagnosis. It is something to do.

(C) Problems to be solved by the invention However, the characteristics of the conventional intensifying screen-film system are inherited as they are, and a new X-ray imaging method using IP is also possible, that is, imaging using both methods. There is no X-ray photography apparatus having a medium transport unit.

In the case of the conventional intensifying screen-film system X-ray photographing system, the close contact between the X-ray film and the intensifying screen is indispensable, and such a close contact mechanism is provided in the film transport unit.
On the other hand, when IP is used, the intensifying screen is not necessary and it is not necessary to consider the adhesion mechanism in the film system.

An object of the present invention is to provide an X-ray quick photographing apparatus provided with a transport unit that can be used for both X-ray film and IP in consideration of the difference between these two methods.

(D) Means for solving the problems The above-mentioned purpose is to have an X-ray film supply magazine, pick up the X-ray film from there, and send it to the carriage by the conveying means, and adhere the X-ray film to the intensifying screen. In the X-ray rapid radiographing apparatus, the carriage holds and waits, and the carriage reciprocates between the standby position and the photographing position.
Supply magazine and IP from this supply magazine
And a holding means provided at a standby position for the carriage of the IP carried on the front surface of the intensifying screen, and a means for carrying the X-rays by the carriage. This is achieved by selectively moving the film and the IP back and forth between the standby position and the shooting position.

(E) Function The film transporting means and the IP transporting means are separated from each other, for example, arranged at opposite positions, and only the film transporting means is connected to the intensifying screen-film contacting means. So that it can be fed in, on the one hand the film transport means and the contact means, and on the other hand the IP transport means,
Each is linked. With such a combined configuration, both X-ray film and IP can be used arbitrarily.

(F) Embodiment A preferred embodiment of the present invention will be described with reference to the drawings.

1 is a front view showing the first embodiment, FIG. 2 is a schematic sectional view taken along line II-II in FIG. 1, and FIG. 3 is a schematic sectional view taken along line III-III in FIG.

In the quick-shooting frame 1, a supply magazine 2 for storing an unphotographed X-ray film, a receive magazine 3 for storing a photographed film, and a supply magazine 14 for storing an unphotographed IP,
... The receive magazine 15 is arranged as shown. A carriage 6 capable of holding both the X-ray film and the IP and transporting them to the photographing position is fixed at a position where the X-ray film or IP can be transferred from each magazine.

The X-ray film or IP is provided with independent suction cups 7 and 17, respectively. Note that 7a is an X-ray film duct, 7b, 7c and 7d are X-ray film pinch rollers, 17a is an IP duct, and 17b, 17c and 17d are IP pinch rollers, and the X-ray film and IP are And each transport mechanism are isolated.

For example, when an X-ray film is selected by an external selection switch (not shown), the unphotographed X-ray film is taken out from the supply magazine 2, and the X-ray film 8 is sent between the intensifying screens 9a and 9b in the carriage 6. Be done. The carriage 6 is provided with an X-ray film carrying roller 10 and an IP carrying roller 11, which are rotating at the same time.

When the X-ray film 8 is fed between the intensifying screens 9a and 9b,
The X-ray film and the intensifying screen are alternately brought into close contact with each other by the close contact mechanism 12 attached to the carriage 6. Then, by pushing an external photographing switch (not shown), the carriage 6 conveys the X-ray film 8 to the photographing position.

The X-ray film that has been photographed is stored in the receive magazine 3 by reversing the conveying roller 10.

Next, when the IP is selected by the selection switch, the unphotographed IP is taken out from the supply magazine 14 and fed into the carriage 6 by the IP transport roller 11. At this time, IP13 is always sent to the front surface of the intensifying screen (X-ray tube device side). After this, the X-ray film is moved to the X-ray imaging position, as with the X-ray film.
The line is photographed and the photographed IP is stored in the receive magazine 15.

(G) Effect of the Invention According to the present invention, both the X-ray film and the IP can be used, and the X-ray film and the IP can be selectively used by switching the switch. It has the effects of being able to digitize images, reduce exposure dose, high-density filtering diagnostic information, and create a network in hospitals.
