Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an X-ray imaging device used with an X111 diagnostic device, and in particular to an X-ray imaging device for transmitting an X-ray image to a remote location.
This article relates to an X-ray imaging 1rtA device that makes it possible to perform X-ray imaging.

[Technical Background of the Invention] Conventionally, when transmitting an X-ray image, that is, an X-ray transmission image to a remote location, X-rays from an X-ray tube pass through a subject in an X-ray diagnostic device, and This X-ray transmission image sandwiches the subject and
The image is taken on the X-ray film of the X-ray imaging device facing the ray tube, and this decoy tRX-ray film is developed. It was transferred by.

This transfer means electronically scans the developed film, converts the gradation information of the image into the intensity of an electrical signal, and then transmits this electrical signal using a telephone line or the like. There is thing-C.

[Problems with the Background Technique] Such conventional X-ray image transfer requires: (1) It takes time to develop the exposed X-ray film.

(2) It is necessary to make a 1lfl shadow on the X-ray film, which requires an expensive X-ray film, which is disadvantageous in terms of performance.

(3) Legend;! i (transfer) must be made into an electrical signal, which requires time to sequentially convert the gradation information of the image into the intensity of the electrical signal.

There are drawbacks such as.

The present invention is used with an X-ray diagnostic device,
In an X-ray imaging device that can transmit the X-ray transmission image obtained by the i-device to a remote location, by directly transmitting the X-ray transmission information of the X-ray transmitted through the object.
U. It is an object of the present invention to provide an X-ray image @ device which is characterized by transmitting an X-ray diagnostic image faster, more accurately, simply, and visually.

[Summary of the Invention] The X19 image @ device according to the present invention receives transmitted X-rays from an X-ray source that have passed through a subject, and temporarily stores and retains the X-ray transmitted image. a first scanner for reading image electrical signals corresponding to each pixel constituting the X-ray transmission image from the radiation detector using two predetermined scanning methods; 1 transmission path for transmitting the image electrical signal read out from the detector,
In addition to this transmission line, there is also a recording converter (connected to 'Mf) that converts the transmitted serial image electric signal into parallel secondary-brother pixel signals for constructing a secondary-brother image;
A second scanner scans and reads out an image signal corresponding to each pixel from this recording converter using a predetermined scanning method in synchronization with the first scanner, and an image signal read out from this recording converter. Based on the above, the apparatus is composed of a recording device for recording the X-ray transmitted image on recording paper.

[Embodiments of the Invention] The present invention will now be described in detail with reference to FIGS. 1 and 2.

X-rays emitted from an X-ray generator 1 including an X-ray tube in an X-ray diagnostic device are transmitted through a subject 2, and the transmitted X-rays are transmitted to, for example, a solid-state radiation detector cell (not shown). are arranged two-dimensionally and output 80A to the lc X-ray detector 3.

Each solid-state radiation detector cell corresponds to one pixel of the X-ray transmission image, and the detector cell covers X-rays equivalent to one pixel of human θ].
This is to obtain an image electrical signal that is proportional to the required X-ray dose equivalent to one pixel. The X-ray transmission image 18 obtained by this X-ray detector 3 is synchronized with J? t +V output from signal generator 4 (scanner 5 operated by No. 3 is
By sequentially scanning and reading out the H radiation detector cells constituting the signal, the signal is transferred to one end of the transmission path 6 of a telephone line, for example. The X-ray image signal, which is an electrical signal input to one end of the transmission line 6 in this way, is transmitted to the other end of the transmission line 6, which is a remote location, through the transmission line 6. It is input to a recording transducer 7 connected to the end. Specifically, by operating the scanner 8 operated by the clock signal from the synchronization reference signal generator 4,
The X-ray image signals serially sent through the transmission line 6 are sequentially input to the recording converter 7 using pixel signals corresponding to each pixel constituting a parallel two-dimensional image. In this recording converter 7, the incident number Ql of each transmitted pixel
After converting the X-ray transmission image electricity (No. 8) corresponding to the line into energy for other recording, such as light or heat, it is output to the recording device 9. Yes,
The device sequentially records images corresponding to the X-ray transmitted image on recording paper (not shown) in accordance with the output signals output from the recording converter 7.

Another embodiment of the present invention will be described with reference to FIG.

Similarly to the first embodiment, the X-rays emitted from the X-ray generating device 1 including the X-ray tube in the X-ray diagnostic apparatus are transmitted through the subject 2, and the transmitted X-rays are transmitted to the X-ray image recording medium. 10 is input to the X-ray detector 3' to the right.
