Abstract

PURPOSE:To use both an X-ray film and a storage type fluorescent plate by providing a conveyor unit which is used for both the X-ray film and storage type fluorescent plate. CONSTITUTION:When the X-ray film is selected with a selection switch, the unexposed X-ray film 8 is taken out of a supply magazine 2 and sent in between intensifying screens 9a and 9b in a carriage 6. At this time, a contacting mechanism 12 provided to the carriage 6 bring the X-ray film and intensifying screens into mutual contact. Then, the carriage 6 carries the X-ray film 8 to a photographic position with a photography switch. The X-ray film after photography is stored in a receiving magazine 3 through the reversing of a conveyor roller. Then, when the storage type fluorescent image plate (IP) is selected with the selection switch, an unexposed IP 13 is taken out of a supply magazine 14 and sent in between front surfaces of the intensifying screens in the carriage 6. Then, photography is carried out in the same process with the X-ray film and the IP is stored in a receiving magazine 15.

Description

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

The present invention relates to an X-ray flash photography device used in X-ray fluoroscopic diagnosis.

(b) Conventional technology The classic intensifying screen-film X-ray imaging system places intensifying screens on the front and back sides of an X-ray film, holds them in close contact with each other, and After taking an X-ray image, the X-ray film is developed and viewed to make a diagnosis. In contrast, snow-covered fluorescent plates (Imaging Plate, or I
A new radiographic method has been developed that performs XtaS imaging using P). This new method uses an IP as an X-ray detector, reads X-ray image data from the IP after X-ray imaging, performs image processing, and displays it on an RT monitor or captures it on recording film. It is used for diagnosis.

(c) Problems that the invention aims to solveHowever, it continued the features of the conventional intensifying screen-film system and also made possible a new X-ray imaging method using IP. There is no existing X-ray rapid photography apparatus that has an imaging medium transport unit to which this method is applied.

In the conventional intensifying screen-film type X-ray imaging system, close contact between the X-ray film and the intensifying screen is essential, and such close contact *n4 is provided in the film transport unit. On the other hand, there is no need for a bottle stand or intensifying screen using IP, and there is no need to provide a close contact mechanism in the film system.

The present invention takes into consideration the links in both of these systems and provides an X!
The purpose is to provide a snapshot photographing device.

(d) Means for solving the problem The purpose or solution of the problem is to provide a means for picking up and transporting X-ray film from an X-ray film supply magazine; a means for picking up and transporting the IP from the supply magazine for phosphor plates (IP); and a close contact means for feeding the taken out X-ray film between the intensifying screens so that they come into close contact with each other; XI film and IP are sent to the shooting position, and at that time, the IP is in front of the intensifying screen or X! ! At can be achieved by having a combination device with a carriage arranged on the tube side.

(e) Function The film transport means and the IPIII transport means are placed apart from each other, for example, in opposing positions, and only the film transport means is connected to the intensifying screen-film contact means, and the carriage is attached to the front surface of the intensifying screen. on the one hand, and the IPi on the other hand.
l They are interlocked with the sending means. With such a combination configuration, both X-ray film and IP can be used arbitrarily.

Kube) Example A preferred embodiment of the invention will be explained based on the drawings.

Fig. 1 is a front view showing one embodiment, Fig. 2 is a schematic cross-sectional view of Fig. 1, and Fig. 3 is a -! II! I
It is a schematic cross-sectional view.

The snapshot frame 1 includes a supply magazine 2 for storing unexposed X-ray film, a receive magazine 3 for storing exposed film, a supply magazine 4 for storing unexposed IP, and a receive magazine 5 for storing exposed IP. are arranged as shown. A carriage 6 that can hold both X-ray film and IP and transports them to an imaging position is fixed at a position where it can receive and deliver X-ray film or IP from each magazine.

Each X-ray film or IP is provided with a separate suction cup 7.17 for removal.

In addition, 7a is the duct for XfIiA film, 7b and 70
and 7d are pinch rollers for X-ray film, 17a is a duct for IP, 17b, 17c, and 17d are pinch rollers for IP, and the xtti film and IP are separated from each other by eight conveyor machines.

For example, when an X-ray film is sent using an external selection switch (not shown), the unexposed X-ray film is taken out from the supply magazine 2, and the X-ray film 8 is placed in the darkness of the intensifying screen 9, 9' in the carriage 6. sent to. An X-ray film feed roller 10 and an IPIII feed roller 11 are installed on the carriage 6 and rotate at the same time.

When the X-ray film 8 is fed into the intensifying screen 9,9', a contact mechanism 12 attached to the carriage 6 brings the X-ray film and the intensifying screen into close contact with each other. Then, by pressing an external photographing switch (not shown), the carriage 6 transports 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 transport roller 10.

Next, when you clean the IP with the selection switch, the unrecorded IP
is taken out from the supply magazine 4 and fed into the carriage 6 by the IPill feed roller 11. At this time, IP13 is required in front of the intensifying screen (XIi tube device side)
sent to. After this, as with X-ray film,
Moved to the X-ray imaging position, X-ray imaging is performed, and the imaged IP
is stored in the receive magazine 5.

(G) Effects of the Invention According to the present invention, it is possible to use both X-ray film and IP, and by changing the switch, X! ! Film and IP can be used selectively, and in this case, the features of the IP-based X-ray imaging method include digitization of images, low temperature with exposure < FA, high-density filing of diagnostic information, and hospital networking. This effect is achieved.
