DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data terminal device used in a radiographic image reproduction processing device, and in particular to an imaging device that irradiates a stimulable phosphor with radiation that has passed through a subject to accumulate and record a radiographic image of the subject. A radiation image including a reading device W1'' that later irradiates the stimulable phosphor with excitation light and reads the accumulated and recorded radiation image, and an image reproduction device that generates a radiation image based on the read electric signal. The present invention relates to a data terminal device used in a reproduction processing device.

The low photosensitivity of stimulable phosphor sheets makes it difficult to optically record identification information as is used in conventional silver halide radiographic systems. Therefore, each fluorophore is given a unique identification code, e.g. one of a series of numbers, which is associated with the patient's name, date of birth,
Data specific to the patient such as gender, that is, subject data, as well as imaging data such as date of imaging, imaging conditions, and area of imaging, are recorded on a slip and sent to the image processing room, where individual phosphor sheets are processed. When reproducing stored images, there is a method of manually inputting these data into an image reproducing converter based on a slip corresponding to the fluorescent note. However, in such a system that centrally manages a large number of phosphor sheets of various sizes, the amount of work involved is enormous, and the possibility of operational errors is considerable.

Therefore, the present invention overcomes these conventional drawbacks, and makes it possible to input these data reliably in correspondence with individual stimulable phosphor sheets, with a relatively simple operation and a low possibility of error. The object of the present invention is to provide a data terminal device for use in a radiographic image reproduction processing device that can perform the following steps.

It can also be obtained by inputting the output of an X-ray irradiation amount detection element (not shown) disposed on the back side of the phosphor sheet 408 as described in Japanese Patent No. 46. Or 1981
As disclosed in patent applications (1), (2), and (3) dated October 16th (applicant Fuji Photo Film Co., Ltd., agent Masashi Yanagida and one other person), before reading and reproducing stored images, Image data such as accumulation amount distribution may be obtained by pre-reading.

FIG. 2 is a block diagram showing the device configuration of the identification information terminal 202 installed in each of the photographing rooms 200A to 20ON in FIG. 1. The identification information terminal 202 includes a magnetic recording head 214 for recording an identification code (14) on a magnetic recording medium label 410 attached to a stimulable phosphor sheet, and a lead 216 thereon.
The identification code recording section 212 is connected to the identification code recording section 212. The identification code recording section 212 is a drive circuit for the head 214. The head 214 is a Sumo wrestler Soto 400 in the cassette type photographing stand 204.
In the cassetteless photographing stand 206, the phosphor sheet 408 is placed in the We feed path from the magazine 402, facing the magnetic recording medium label 410, at the position where the magnetic recording medium label 410 is inserted.

In the cassette type photographing table 204, the label 410 comes into contact with the head 214 through an opening 414 in a part of the cassette 400. The recording section 212 is connected via a lead 218 to an identification information control section 224, which will be described later.

The identification information terminal 202 in FIG. 2 is used as an input device for inputting the aforementioned subject data and imaging data.
- a card 220 and a card reader 222. Keyboard 220 basically has numeric keys and letter keys
However, it is advantageous to also include a card reader (such as a magnetic card reader or punch card reader) and/or a mark sheet reader that can directly read the identification card or medical record of the patient 210. For example, a magnetic An identification card having a recording strip is magnetically read by a card reader 222, and the above-mentioned subject data can be entered.The imaging data such as the date of imaging and the tube voltage are entered using the keyboard 220, In the X-ray imaging operation device 250 of 204, imaging condition data is inputted from the dials and switches set by the radiographing technician, and these values are inputted from the sensor 252 provided on the imaging platform 204, especially the above-mentioned accumulation amount distribution of captured images, etc. Image data may also be obtained.

A keyboard 220 and a card reader 222 are connected to an input 226 of the identification information control section 224. The identification information control unit 224 is a control device that controls the entire identification information terminal 202, and may be realized by, for example, a microconbeater. Its important function is to generate a unique identification code to be assigned to the phosphor sheet 408 for each shot and send it to the identification code recording section 212, and to receive it from the keyboard 220, card reader 222, etc. by the read 226. The purpose of this process is to associate the input data generated with the internally generated identification code. Therefore, these identification codes and input data are temporarily stored, and are provided with a soter or memory, and are uniquely stored in response to a trigger signal ST given to the lead 228 by the operation of the radiographing operator from the X-ray imaging operation device 250 of the imaging stage 204. It has a circuit, for example, a counter, that uniquely generates an identification code. The unique identification code for the phosphor sheet 408 may, for example, consist of one of a series of numbers and include a fixed portion and a variable portion. The fixed part is, for example, a code unique to the identification information terminal device 2024 or one of the photographing rooms 200A to 20ON, and is semi-fixedly set in the identification information control unit 224 by, for example, program setting. The variable part may be a serial number within the identification information terminal 202, such that, for example, the upper digit corresponds to the daily number, and the lower digit (17) indicates one of the serial numbers assigned on the day corresponding to the date. You can also do this.

As the signal ST, a shot signal from an X-ray photographing button (not shown) in the operating device 250 of the photographing table 204 or a transmission signal of the phosphor sheet 408 can be used. When the trigger signal ST is activated, the identification information control unit 224 sends the generated identification code to the identification code recording unit 212 to have the head 214 record it on the magnetic recording medium label 410, and also records this identification code and the above-mentioned input data. to output 230.

A display unit 240 that displays the overall operating status of the identification information terminal 202 is connected to the identification information control unit 224. For example, a cathode ray tube (CRT) display or the like is advantageous, but a display unit 240 that is integrated with the keyboard 220 is also suitable. It can also be a writer. This allows the operator to grasp the progress status of the entire system, and the sensor 214 of the identification code reader 212,
Alternatively, instructions on how to input data can be obtained from the keyboard 220, card league 222, or the like. In addition, the phosphor sheet 4 is displayed without any data being input.
In order to prevent erroneous operations such as image recording, i.e., shooting, being performed on the 08, if the minimum required data, such as the patient code, is not entered, a display indicating "Shooting allowed" is displayed on the display unit 240. It may be configured so that it is not displayed or audibly displayed. In order to do so, the identification information control unit 22 checks whether the minimum necessary data has been input.

Receivers 3028 to (22) 302N and reception control units 3068 to 306N may be omitted to perform metallic parallel transmission.

Output 308 of each of these reception control units 306A to 306N
8 to 308N are connected to the input of the transmission network control unit 310,
It also houses a data entry terminal 350. The data input terminal 350 is a keyboard 31 that manually inputs the identification code, subject, and imaging data of the sheet 408 from the imaging room where the identification information terminal 202 is not installed based on the slip or memo.

Although blocks 310 and 316 are shown in FIG. 3 as functionally separate blocks, physically they can be implemented as one by a microprocessor. In addition to this, the overall control unit 316 performs various controls of the overall control system 300 as described later.

The file storage unit 318 is a storage device for storing the identification code of the phosphor sheet 408 and files of the corresponding subject data and imaging data, and is preferably a semiconductor memory. However, since semiconductor memory is volatile, a backup file 320 is provided so that even if the stored data is destroyed when the overall control system 300 goes down, it can be effectively dealt with during subsequent failure recovery. This is, for example, a non-volatile mass storage device such as a floppy disk device or a magnetic bubble memory, and has a redundant configuration that always has a copy of the stored contents of the file storage section 318.

For example, input data including necessary subject data, imaging data, and image data is input from the keyboard 220, card reader 222, and sensor 252 of the identification information terminal 202 to the identification information control unit 224, and then the operating device 250
When the X-ray photography button (not shown) is operated and X-ray photography is performed, a bird generated on the lead 228 (30) responds to the signal ST, and the identification information control unit 224 controls the transmission control unit 1232, 1236 and the communication line 404 to the overall control system 300 along with a code for identifying the identification information terminal 202. An example of this data formant is shown in FIG. 7(A).

The overall control section 316 of the overall control system 300 shown in FIG.
Transceivers 1302A-1302N.

When these input data are received via the transmission control units 1.306A-1306N and the transmission network control unit 310, the information unique to this data string, that is, unique to the identification information terminals 202A to 202N that transmitted the input data, is transmitted. An identification code unique to Naware/ζxal photography is created and sent back to the identification information terminal 202 through a route opposite to that of receiving the input data. This sign month form is the 71st number (B
). This identification code is used for identification information terminals 202A to 202
If it is configured to include 2N identification codes, it will be convenient for input data analysis processing, etc.: However, it is not necessarily necessary to include such codes, and the overall control system 300 can be configured as one. Serial numbers may be assigned sequentially. To this end, the overall control unit 316 includes a table or counter in memory for assigning identification codes.

Note 4 returned to identification information terminals 202A to 202N
The identification code 08 is recorded on the magnetic recording medium label 410 of the fluorescent sheet 408 via the identification code recording unit 212 and the recording head 214 under the control of the identification information control unit 224.
recorded in

In this embodiment, the overall control unit 316 uniquely determines the identification code regardless of the individual identification information terminals 202A to 202N in response to the generation of a request for an identification code from each identification information terminal 202A to 202N, that is, the reception of input data. Since the identification codes of the sheets 408 can be sequentially assigned,
The storage area of the file storage unit 318 can be used efficiently. That is, each time the overall control unit 316 receives input data from the identification information terminals 2028 to 202N, it suffices to sequentially allocate a storage area in the file storage unit 318 to store this input data, and it is sufficient for later retrieval using the sheet identification code. can also be done easily and quickly. Note that the magnetic recording medium label 410 in the embodiment of the present invention is not limited to a label. The phosphor sheet may be coated with a magnetic recording medium at a predetermined position, or any material may be used as long as the phosphor sheet is provided with a magnetically recordable portion.

The data terminal device used in the radiographic image reproduction processing apparatus according to the present invention is configured in this way, so that data related to 4'jl'i types of images can be sent to the data processor for image processing each time radiography is performed in each radiographing room. Since input can be performed in real time, there is no need for manual input due to batch processing of large amounts of data in the image processing room as in the past, and data input is easy, reducing the workload and reducing the possibility of operational errors. stomach. Therefore, in the image processing room, which is an image processing center, it is possible to centrally manage a large number of stimulable phosphor sheets of various types and to perform individual processing (33) of accumulated images according to individual shooting conditions quickly and reliably. can be done.
