Abstract

In an X-ray imaging device (1) according to the present invention, an ID sticker printing unit (21) prints an ID sticker. The ID sticker is to be applied to a triage tag that is attached to a subject and the ID sticker bears a subject ID issued by an ID issuing unit (19). The subject ID identifies the imaged subject of a formed X-ray image. Thus, reference to the subject ID on the ID sticker applied to the triage tag enables identification of the imaged subject of the X-ray image. In addition, since the ID sticker bearing the subject ID is applied to the triage tag, the subject ID issued by the ID issuing unit (19) does not need to be hand-written onto the triage tag. Thus, a step of writing the subject ID can be omitted and a human error in doing so can be avoided. Therefore, the subject and the X-ray image acquired with respect to the subject can be efficiently and reliably associated.

Description

X-ray equipment

The present invention relates to an X-ray imaging apparatus that performs X-ray imaging on a patient, and particularly relates to a technique for associating a patient with X-ray image data acquired for the patient in a disaster or the like.

A medical institution is equipped with an X-ray imaging apparatus for irradiating a patient with X-rays and acquiring an X-ray image. When it is determined that a patient needs to be diagnosed with an X-ray image, the patient's identity information is usually newly obtained from a hospital information system (HIS: Hospital Information System) or a radiation information system (RIS: Radiology Information). Register to System).

The Hospital Information System (HIS) handles all information related to hospital management such as patient information (patient name, ID number, etc.) and accounting-related information. The Radiation Information System (RIS) receives an X-ray imaging request from the clinical department, and manages information related to X-ray imaging conditions such as the patient to be X-rayed, the site to be X-rayed, and the equipment to be X-rayed. , Send a radiography request to the radiology department. In the radiology department, X-ray imaging is performed based on the X-ray imaging conditions requested for imaging to acquire an X-ray image. In recent years, there has been reported an X-ray imaging apparatus that is connected to an HIS or RIS online for efficient medical treatment and directly receives the contents of an imaging request from a clinical department (for example, Patent Document 1).

On the other hand, when a large number of unidentified victims occur during a disaster, it is difficult to quickly issue and manage patient information such as ID numbers using the HIS. For this reason, it is not possible to issue an imaging request by RIS. In addition, it is necessary to appropriately treat and transport each of a large number of injured persons under circumstances where supplies and human resources are limited. In such a case, an identification tag called a triage tag is used in order to identify a large number of victims and quickly determine the treatment priority of the victims (see, for example, Patent Documents 2 and 3).

The triage tag is a paper medium with a marker that displays the classification of treatment priority (triage classification) of the victim. Information about the victim's name and address, or when the victim is injured and is accommodated in a hospital, etc. Can describe information about the medical institution. Therefore, conventionally, the temporary patient ID issued by the X-ray imaging apparatus is handwritten and transferred to a triage tag on a paper medium, thereby associating the patient with the X-ray image.

The conventional example will be specifically described with reference to the flowchart of FIG. In the X-ray imaging apparatus according to the conventional example, after performing X-ray imaging for the patient at the time of a disaster (S1), the X-ray image is acquired and a temporary patient ID for identifying the patient is issued. (S2). Then, the surgeon manually transcribes the temporary patient ID automatically issued by the X-ray imaging apparatus to the triage tag possessed by the victim (S3).

Then, after the provisional patient ID is transcribed, the surgeon makes a diagnosis using the X-ray image (S4). Then, the temporary patient ID issued when the X-ray image is acquired is matched with the temporary patient ID recorded on the triage tag possessed by the victim. In this way, a victim who has the triage tag to which the provisional patient ID has been transcribed is identified (S5), and a therapeutic action is performed based on the information obtained by the diagnosis of the X-ray image (S6).

However, the conventional example having such a configuration has the following problems.
That is, in the conventional X-ray imaging apparatus, since the provisional patient ID issued by the X-ray imaging apparatus is transferred to the triage tag by hand, it takes time and effort to transfer, and a human error occurs during the transfer. . For this reason, it may be difficult to efficiently and accurately associate the patient with the acquired X-ray image data.

The present invention has been made in view of such circumstances, and can efficiently and reliably associate a subject and X-ray image data acquired for the subject in an emergency such as a disaster. An object of the present invention is to provide an apparatus.

In order to achieve such an object, the present invention has the following configuration.
That is, an X-ray imaging apparatus according to the present invention includes an X-ray source that irradiates a subject with X-rays, an X-ray detection unit that detects X-rays irradiated from the X-ray source and transmitted through the subject, An image forming unit that forms an X-ray image based on a detection signal output from the X-ray detection unit, and a subject that issues subject identification information that identifies a subject related to the X-ray image formed by the image forming unit. A specimen identification information issuing means; a storage means for storing the X-ray image and the subject identification information in association with each other; and the subject identification information issued by the subject identification information issuing means; And a sticker paper printing means for printing the tag sticker paper to be attached to the triage tag attached to the head.

According to the X-ray imaging apparatus of the present invention, the sticker paper printing unit prints the tag sticker paper on which the subject identification information issued by the subject identification information issuing unit is described. The tag affixing paper is affixed to a triage tag attached to a subject and describes subject identification information. The object identification information specifies the object related to the formed X-ray image. Therefore, by referring to the subject identification information described on the sticker attached to the triage tag, the subject whose X-ray image is taken can be specified.

In addition, since the tag sticker on which the subject identification information is described is attached to the triage tag, it is not necessary to hand-write the subject identification information issued by the subject identification information issuing means to the triage tag. Therefore, the step of transferring the subject identification information can be omitted, and it is possible to avoid the occurrence of an artificial error during the transfer. Therefore, it is possible to efficiently and reliably associate the subject with the X-ray image acquired for the subject.

Further, in the X-ray imaging apparatus according to the present invention, it is preferable that the tag sticker paper printed by the sticker paper printing means is a seal type.

According to the X-ray imaging apparatus of the present invention, since the tag sticker is in a seal form, the operator can triage the subject identification information by a simple operation of sticking the sticker constituting the tag sticker on the triage tag. Can be attached to a tag. Therefore, the subject and the X-ray image acquired for the subject can be associated more efficiently and reliably.

The X-ray imaging apparatus according to the present invention further includes triage classification input means for inputting a triage classification determined based on the X-ray image formed by the image forming means, and the sticker sheet printing means performs printing. In addition to the subject identification information, the tag affixing paper preferably describes the triage classification input by the triage classification input means.

According to the X-ray imaging apparatus of the present invention, the sticker sheet printing means prints the tag sticker sheet on which the object identification information and the triage classification are described. In this case, the triage classification described on the tag sticker is a triage classification newly determined based on the X-ray image formed by the image forming means. Therefore, it is possible to determine the treatment priority and the like based on the triage classification newly determined by referring to the X-ray image, not the triage classification determined before X-ray imaging. Therefore, it is possible to perform a treatment action based on a more appropriate priority order for the victim at the time of disaster.

Further, the X-ray imaging apparatus according to the present invention preferably further comprises a print instruction means for instructing printing of the tag sticker paper by the sticker paper print means.

According to the X-ray imaging apparatus of the present invention, the tag sticker paper is printed by the sticker paper printing means under the instruction of the print instruction means. That is, the tag sticker can be printed at an arbitrary timing by operating the print instruction means. Further, there are cases where it is not necessary to print the tag affixing paper on which the subject identification information is described, for example, the identity of the subject is already known. In this case, by not instructing the printing instruction means to print the tag sticker, it is possible to reduce the labor and cost for printing the tag sticker.

Moreover, it is preferable that the X-ray imaging apparatus according to the present invention further includes a carriage on which the X-ray imaging apparatus main body is mounted and a drive mechanism that moves the carriage.

According to the X-ray imaging apparatus according to the present invention, the X-ray imaging apparatus includes the carriage on which the X-ray imaging apparatus main body is mounted and the drive mechanism for moving the carriage, so that the operator can move the X-ray imaging apparatus. In an emergency such as a disaster, a simple examination room is often constructed outdoors or in a refuge using an X-ray imaging apparatus that enables movement, and X-ray imaging is often performed in the constructed simple examination room. In such a case, by using a mobile X-ray imaging apparatus equipped with a sticky paper printing means, the relationship between the patient and the X-ray image can be efficiently and reliably obtained under more diverse conditions during a disaster. It becomes possible to record.

A printing unit 21, an input unit 23, a storage unit 25, a print instruction unit 27, and a main control unit 29 are attached.

The X-ray irradiation control unit 11 is configured to output a high voltage to the X-ray tube 5. And based on the high voltage output which the X-ray irradiation control part 11 gives, the X-ray dose which the X-ray tube 5 irradiates, and the timing which irradiates X-rays are controlled. The detector control unit 13 controls the operation of reading the electrical signal converted by the X-ray detector 9, that is, the X-ray detection signal.

The X-ray image forming unit 15 is provided after the X-ray detector 9 and forms an X-ray image of the subject M based on the X-ray detection signal output from the X-ray detector 9. The monitor 17 displays the X-ray image formed by the X-ray image forming unit 15. The X-ray image forming unit 15 corresponds to an image forming unit in the present invention.

The ID issuing unit 19 is provided in the subsequent stage of the X-ray image forming unit 15. The ID issuing unit 19 issues image identification information for identifying the formed X-ray image and a subject ID for specifying the subject of the X-ray image. The ID sticker printing unit 21 prints a sticker on which the subject ID issued by the ID issuing unit 19 is described. The ID issuing unit 19 corresponds to the subject identification information issuing unit in the present invention, and the ID sticker printing unit 21 corresponds to the sticker printing unit in the present invention.

The storage unit 25 stores the X-ray image formed by the X-ray image forming unit 15, the image identification information issued by the ID issuing unit 19, the subject ID, and the like in association with each other. The printing instruction unit 27 transmits a control signal to the ID sticker printing unit 19 to print a sticker on which the subject ID is described. The main control unit 29 controls the X-ray irradiation control unit 11, the detector control unit 13, the X-ray image forming unit 15, the ID issuing unit 19, the storage unit 25, and the print instruction unit 27. The storage unit 25 corresponds to a storage unit in the present invention.

<Description of Operation According to Example 1>
Next, the operation of the X-ray imaging apparatus 1 according to the first embodiment will be described. FIG. 3 is a flowchart for explaining an operation process of the X-ray imaging apparatus 1 according to the first embodiment.

Step S1 (X-ray image formation)
First, the subject M is placed on the top 3 as shown in FIG. Next, the operator operates the collimator 7 to adjust the X-ray irradiation field. The operator then operates the input unit 23 to instruct conditions relating to X-ray irradiation, such as the number of X-ray images to be taken and the values of tube voltage and tube current. The information input to the input unit 23 is transmitted to the main control unit 29, and the main control unit 29 outputs a control signal to the X-ray irradiation control unit 11 based on the transmitted information. The X-ray irradiation control unit 11 irradiates the subject M with X-rays 5a from the X-ray tube 5 based on the control signal. X-rays 5 a irradiated from the X-ray tube 5 pass through the subject M and are detected by the X-ray detector 9.

The X-ray detected by the X-ray detector 9 is converted into an electric signal. The electrical signal converted in the X-ray detector 9 is read out by the detector control unit 13. The read electrical signal is output to the X-ray image forming unit 15 as an X-ray detection signal. The X-ray image forming unit 15 forms an X-ray image based on the output X-ray detection signal. The formed X-ray image is displayed on the monitor 17. The X-ray image forming unit 15 forms the number of X-ray images corresponding to the information input to the input unit 23.

Step S2 (issue of subject ID)
When the X-ray image is formed, the ID issuing unit 19 issues image identification information and a subject ID for each of the formed X-ray images. The image identification information is information for identifying each X-ray image determined based on a standard such as DICOM (Digital Imaging and Communications in Medicine), and is different information for each image. On the other hand, since the subject ID is information for identifying the subject of the X-ray image, the same subject ID is issued for a plurality of X-ray images acquired for the same subject. The subject ID corresponds to subject identification information in the present invention.

As an example, a case where three X-ray images are taken for the subject M will be described with reference to FIG. The operator inputs to the input unit 23 that three X-ray images of the subject M are to be captured. The X-ray image forming unit 15 forms three

X-ray images

15a, 15b, and 15c based on the control signal.

At this time, the ID issuing unit 19 issues the image identification information 19a and the subject ID 19M to the X-ray image 15a. The X-ray image 15b and the X-ray image 15c are images different from the X-ray image 15a, but the imaging target is the same subject M. Therefore, the ID issuing unit 19 issues image identification information 19b and a subject ID 19M to the X-ray image 15b. Then, the ID issuing unit 19 issues image identification information 19c and a subject ID 19M to the X-ray image 15c. Each of the issued image identification information and subject ID is transmitted to the storage unit 25 together with the X-ray image and stored in association with each other.

Step S3 (ID seal printing)
After the image identification information and the subject ID are issued for all the X-ray images, the ID sticker on which the subject ID is described is printed. In other words, the operator operates the input unit 23 to input a command for printing the ID sticker. The command input to the input unit 23 is transmitted to the main control unit 29, and the main control unit 29 outputs a control signal to the print instruction unit 27 based on the transmitted information.

The printing instruction unit 27 outputs a signal instructing the ID sticker printing unit 21 to print the ID sticker on which the subject ID is described based on the control signal. The ID sticker printing unit 21 prints the ID sticker 31 based on the signal. The print instruction unit 27 corresponds to the print instruction means in the present invention, and the ID seal 31 corresponds to the tag sticker in the present invention.

Step S4 (Attach ID sticker to triage tag)
As shown in FIG. 5A, the printed ID sticker 31 includes an ID character string 31a that makes the subject ID readable and an ID barcode 31b that makes the subject ID barcode. Yes. The operator can confirm the subject ID by viewing the ID character string 31a. Further, the operator can confirm the subject ID more reliably by reading the ID barcode 31b using a barcode reader.

And as shown in FIG.5 (b), the ID seal | sticker 31 is a seal | sticker type. The operator peels off the ID sticker 31 from the mount 31 c and attaches it to the triage tag 33 attached to the subject M.

Step S5 (diagnosis of X-ray image)
After attaching the ID seal 31 to the triage tag 33, the operator makes a diagnosis on the subject using the formed X-ray image. As an example, X-ray image data is transmitted to a server connected to the X-ray imaging apparatus 1 using a radiological image information system (PACS) or the like. In the examination room, X-ray image data is received from the server, and a precise diagnosis is performed based on the image data.

Step S6 (identify triage tag with ID sticker)
A subject ID is attached to the X-ray image data transmitted to the server together with the image identification information. When an X-ray image is diagnosed and a treatment policy or the like is determined, the operator specifies the triage tag 33 in which the same subject ID as the subject ID attached to the X-ray image data is written. That is, the patient who has the triage tag 33 to which the ID seal 31 on which the same subject ID is described is attached is specified.

Step S7 (treatment based on diagnosis of X-ray image)
The injured person specified in step S6 is the subject M who has performed the X-ray image in step S1. Therefore, an appropriate treatment is performed on the subject M based on the diagnosis result performed in step S5. Through such a process, in an emergency situation such as a disaster, the subject and the X-ray image acquired for the subject can be reliably associated and appropriate treatment can be performed.

<Effects of Configuration of Example 1>
Here, effects obtained based on the configuration according to the first embodiment will be described. In an X-ray imaging apparatus having a conventional configuration, a provisional patient ID for identifying a sick person is issued for an X-ray image. The operator visually confirms the provisional patient ID on a monitor or the like, and transcribes the provisional patient ID on the triage tag by handwriting. In this case, since the temporary patient ID is about 10 digits as an example, it takes time to visually confirm and transfer the temporary patient ID having a large number of digits, and the burden on the operator is large. In addition, since the provisional patient ID is handwritten, there is a problem that an artificial transcription error occurs.

On the other hand, in the X-ray imaging apparatus according to the first embodiment, the ID sticker printing unit 21 prints the ID sticker 31 on which the subject ID issued by the ID issuing unit 19 is described. The ID sticker 31 is a sticker on which the subject ID is described, and is attached to a triage tag 33 attached to the subject by peeling off the mount. Therefore, a subject ID having about 10 digits can be easily and reliably attached to the triage tag 33. The subject ID is used to specify the object to be imaged of the formed X-ray image. Therefore, by referring to the ID sticker 31 affixed to the triage tag 33, it is possible to reliably identify the subject that has taken the X-ray image.

In addition, since the ID sticker 31 on which the subject ID is described is attached to the triage tag, it is not necessary to hand-write the subject ID issued by the ID issuing unit 19 to the triage tag 33. Therefore, the process of transferring the subject ID can be omitted, and it is possible to avoid the occurrence of an artificial error when transferring. Therefore, it is possible to efficiently and reliably associate the subject with the X-ray image acquired for the subject.

Embodiment 2 of the present invention will be described below with reference to the drawings. Note that the same components as those in the X-ray imaging apparatus according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

In the X-ray imaging apparatus according to the second embodiment, the input unit 23 is configured to input a triage classification. The ID sticker printed by the ID sticker printing unit 21 has a configuration in which the triage classification input by the input unit 23 is described in addition to the subject ID. In the second embodiment, the input unit 23 corresponds to the triage classification input unit in the present invention.

<Description of Operation According to Second Embodiment>
Next, the operation of the X-ray imaging apparatus 1 according to the first embodiment will be described. FIG. 6 is a flowchart for explaining an operation process of the X-ray imaging apparatus 1 according to the second embodiment. First, the X-ray image forming unit 15 forms an X-ray image by the same process as step S1 of the first embodiment, and displays the formed X-ray image on the monitor 17 (step S1A).

Step S2A (input of triage classification)
The operator examines the X-ray image displayed on the monitor 17 and confirms that the subject M is not seriously injured. Then, a new triage classification is determined based on the inspection result. That is, when a severe injury is newly found as a result of the examination of the X-ray image, a triage classification having a higher treatment priority than the original triage classification is newly determined. On the other hand, if it is initially determined that the treatment priority is high, but it is determined that there is no need for urgent treatment as a result of the examination of the X-ray image, a new triage classification with a lower treatment priority than the beginning is newly added. judge. The operator inputs the newly determined triage classification into the input unit 23.

Step S3A (Issuance of subject ID)
The operator causes the image identification information and the subject ID to be issued for each X-ray image in the same process as step S2 of the first embodiment. Note that the order of steps S2A and S3A may be reversed, and the subject ID may be issued first.

Step S4A (print ID sticker)
After a new triage classification is input and a subject ID is issued, an ID sticker on which the subject ID is described is printed. That is, the operator inputs an instruction for printing the ID sticker by operating the input unit 23 in the same process as step S3 of the first embodiment. The print instruction unit 27 outputs a signal instructing the ID sticker printing unit 21 to print the ID sticker based on the control signal. The ID sticker printing unit 21 prints an ID sticker 35 as shown in FIG. 7 based on the signal.

Step S5A (Attach ID sticker to triage tag)
As shown in FIG. 7A, the printed ID seal 35 is newly determined as an ID character string 35a that makes the subject ID readable, and an ID barcode 35b that makes the subject ID barcode. The triage classification 35c is described. And as shown in FIG.7 (b), the ID seal | sticker 35 becomes a seal | sticker type. The operator peels off the ID seal 35 from the mount 35d and affixes it to the triage tag 33 attached to the subject M.

Step S6A (diagnosis of X-ray image)
After attaching the ID seal 35 to the triage tag 33, the operator performs a precise diagnosis on the subject using the formed X-ray image in the same process as step S5 of the first embodiment. By making a precise diagnosis, an appropriate treatment policy for the subject is determined.

Step S7A (identify triage tag with ID sticker)
When an X-ray image is diagnosed and a treatment policy is determined, the operator records the same subject ID as the subject ID attached to the X-ray image data in the same process as step S6 of the first embodiment. The triage tag 33 is identified.

Step S8A (treatment based on diagnosis of X-ray image)
After the triage tag 33 is specified, the subject M to which the specified triage tag 33 is attached is treated based on the diagnosis result performed in step S6A. Through such a process, in an emergency situation such as a disaster, the subject and the X-ray image acquired for the subject can be reliably associated and appropriate treatment can be performed.

<Effects of Configuration of Example 2>
Here, effects obtained based on the configuration according to the second embodiment will be described.

At the beginning of a disaster, it is difficult to make a detailed diagnosis of the inside of a human body by X-ray photography or the like, and therefore triage classification is determined based on respiration and pulse. Therefore, the triage classification determined at the beginning of the disaster may be different from the triage classification determined based on the X-ray image. That is, although it is initially determined that the treatment priority is low, there is a case where a severe injury is found as a result of X-ray imaging and it is determined that the treatment priority is high. In this case, if the treatment is performed according to the original triage classification, there is a concern that a serious situation may occur because the treatment for the seriously ill patient is postponed.

On the other hand, on the other hand, as a result of X-ray photography, it may be judged that the treatment priority is actually lower than the original triage classification. In this case, if treatment is performed according to the original triage classification, the patient with low priority is actually treated with priority. For this reason, the result is contrary to the purpose of triage of obtaining the best results using limited supplies and human resources in emergency such as disasters.

Therefore, in the X-ray imaging apparatus according to the second embodiment, the input unit 23 is configured to input the triage classification. The ID sticker printed by the ID sticker printing unit 21 has a configuration in which the triage classification input by the input unit 23 is described in addition to the subject ID. For example, the operator displays an X-ray image formed by X-ray imaging on a monitor. Then, by examining the X-ray image, it is determined whether or not the subject is injured.

When it is determined that the treatment priority is high as a result of examining the X-ray image, such as a serious injury or illness, a triage classification having a high treatment priority from the beginning is newly determined and input to the input unit. Since the newly determined triage classification is described on the ID sticker, the new triage classification can be easily and reliably applied to the triage tag attached to the subject by attaching the ID sticker. Will be attached. As a result, the treatment is prioritized based on the new triage classification, so that the subject can receive an appropriate treatment in the event of a disaster.

On the other hand, as a result of examining the X-ray image, if it is determined that the treatment priority is low from the beginning, a triage classification having a low treatment priority from the beginning is newly determined and input to the input unit. A new triage classification is written on the triage tag attached to the subject by the pasted ID sticker. As a result, it is possible to avoid giving a treatment or the like preferentially to a patient who is actually mild to a patient with a severe degree. Accordingly, limited supplies and human resources can be used more effectively in the event of a disaster.

The present invention is not limited to the above embodiment, and can be modified as follows.

(1) In each of the above-described embodiments, the stationary X-ray imaging apparatus fixed in the imaging room has been described. However, the present invention is not limited to this. That is, the present invention may be applied to a mobile X-ray imaging apparatus including a carriage 37, a drive mechanism such as a drive wheel 39, and an operation handle 41 as shown in FIG. In an emergency such as a disaster, it is difficult to move a large number of victims to an imaging room with a stationary X-ray imaging apparatus. Therefore, in many cases, a simple examination room is constructed outdoors or in a refuge using a mobile X-ray imaging apparatus, and X-ray imaging is performed in the constructed simple examination room. In such a case, by using the mobile X-ray imaging apparatus having the configuration according to each embodiment, the relationship between the patient and the X-ray image can be obtained without using an information system such as HIS. It becomes possible to record efficiently and reliably.

(2) In each of the above-described embodiments, an X-ray image is formed by irradiating a subject in a supine posture to form an X-ray image. It is good also as a structure which forms an image.

(3) In each of the above-described embodiments, after the X-ray image is formed, the ID sticker is printed via the print instruction unit 27 in step S4. However, the present invention is not limited to this. That is, the ID seal may be printed at an arbitrary timing after the subject ID is issued. Further, the print instruction unit 27 may be omitted in the X-ray imaging apparatus 1 and an ID sticker may be automatically printed after an X-ray image is formed.
