Description

The present invention relates to an imaging apparatus, an imaging system , an imaging method, and a program used in, for example, a portable X-ray imaging apparatus that uses an X-ray flat panel sensor as imaging means.

  Conventionally, for example, as an X-ray imaging apparatus, there is a portable X-ray imaging apparatus for imaging a patient who cannot be carried to an X-ray imaging room. This X-ray imaging apparatus includes an X-ray tube, a high-pressure generator, a battery, and the like, and is carried and used in a plurality of hospital rooms together with an imaging plate using a film cassette or a photostimulable fluorescent screen.

On the other hand, in recent years, an X-ray imaging apparatus using an X-ray flat panel sensor made of amorphous silicon or the like instead of a film has been proposed. An X-ray imaging apparatus using such a sensor is
・ The captured image can be confirmed immediately after shooting.
-Multiple images can be taken with a single sensor.
-Image processing, image transfer, or filing as a digital image becomes easy.
It is thought that it will spread further in the future.

FIG. 6 shows a configuration of an in-hospital X-ray imaging system 800 using an X-ray flat panel sensor.
In the hospital room here, as shown in FIG. 6, there are three general radiographing rooms 810 (1) to 810 (3), and each radiographing room 810 (1) to 810 (3) The standing position photographing apparatus and the standing position photographing apparatus controlled by the control unit are installed one by one.
For example, in the photographing room 810 (1), a standing photographing device 810 (1-a) and a standing photographing device 810 (1-b) are installed, and these standing photographing devices 810 (1-a). And the supine photographing apparatus 810 (1-b) is controlled by the control unit 820 (1).

  For the sake of simplicity, in the following description, any of the shooting rooms 810 (1) to 810 (3), the shooting rooms 810 (X) of the shooting rooms 810 (1) to 810 (3), In addition, attention is paid to the control unit (X), the standing position photographing apparatus 810 (X-a), and the lying position photographing apparatus 810 (X-b) related thereto.

  The control unit 820 (X) performs various types of image processing on the captured image obtained by photographing with the standing photographing device 810 (Xa) or the standing photographing device 810 (Xb), and performs the processing. The subsequent captured image is transmitted to the printer 830, the image filing device 840, the viewer 850, or the like via the image network 860.

In addition to the above configuration, a network (RIS network) 880 for a radiation information system (RIS) is provided in the hospital.
The RIS information (RIS information) includes various information such as a patient name, patient ID, imaging region, number of images, imaging conditions, doctor name in charge. Such RIS information is transferred via the RIS network 880 to RIS terminals 870 (1) to 870 (3) provided corresponding to the imaging rooms 810 (1) to 810 (3).

  Accordingly, the photographer in the radiographing room 810 (X) uses the RIS terminal 870 (X) to confirm the patient to be radiographed, and then the standing radiographing apparatus 810 (Xa) or the supine radiographing apparatus 810 (Xb). Start shooting with.

At this time, the control device 820 (X) sends a patient to the standing imaging device 810 (X-a) and the supine imaging device 810 (X-b) based on the RIS information from the RIS terminal 870 (X). Name, patient ID, imaging region, imaging conditions, etc. are automatically set.
Similarly, the control device 820 (X) also applies to the X-ray generator (not shown) based on the RIS information from the RIS terminal 870 (X), the X-ray tube voltage, the X-ray tube current, and the imaging time. , X-ray diaphragm etc. are automatically set.

  When the photographing in the photographing room 810 (X) (photographing based on the various automatic settings described above) is completed, the control unit 820 (X) displays the standing photographing device 810 (X-a) or the standing photographing device. RIS information from the RIS terminal 870 (X) is added as supplementary information to the photographed image obtained at 810 (X-b), and the photographed image after the supplementary information is added, for example, as a medical image transfer protocol Using standard DICOM (Digital Imaging & Communication in Medicine) 3.0 or the like, the image data is transferred to the printer 830, the image filing device 840, or the viewer 850 via the image network 860. This completes the series of shooting.

  As described above, in the imaging room 810 (X), the RIS terminal 870 (1) on the RIS network 880, the standing position imaging apparatus 810 (X-a) and the supine position imaging apparatus 810 (in the imaging room 810 (X) X-b), the printer 830, the image filing device 840, the viewer 850, etc. on the image network 860 function organically, contributing to labor saving and automation of X-ray imaging.

  On the other hand, as shown in FIG. 6 above, a portable X-ray imaging apparatus 900 that carries a set of devices to a hospital room and cannot capture images cannot be connected to other devices via a network or the like. Various methods have been proposed to match information (patient information) related to a patient as a subject and various imaging conditions.

For example, in a portable X-ray imaging apparatus using a film cassette, the following method is adopted as a method for matching patient information, imaging conditions, and the like with a captured image.
First, the doctor in charge of the patient writes the examination site of the patient in the examination request form, and sends the examination request form to the person in charge of radiography (radiologist).
Next, the radiologist who has received the examination request form creates an ID imprint card on which the patient name, patient ID, date of birth, examination site, etc. are written based on the examination request form.
When the imaging of the patient is completed, the radiologist writes the information on the ID copying card on the film by the information copying device. Thereby, the captured image on the film can be matched with the patient information.

However, the captured image on the film used in the conventional portable X-ray imaging apparatus as described above, information on the patient who is the subject of the captured image (patient information), various imaging conditions, and the like. In the method for matching, since the amount of information that can be written on the ID imprint card is limited in space, only the minimum necessary information can be imprinted on the film. Therefore, there is a problem that sufficient information about the patient or the like corresponding to the captured image is not transmitted to the radiogram interpreter.
In addition, since this method is a method of writing information in an analog manner, it is not suitable for searching, filing, and the like today as digitization progresses.

Therefore, in order to solve the above problem, for example, Patent Document 1 discloses a captured image and radiation information (patient information) in a portable X-ray imaging apparatus using a storage phosphor as follows. A matching method has been proposed.
In this method, first, a nonvolatile memory that can be read from the outside is attached to the cassette, and a patient identification code, a storage phosphor identification code, an imaging region, an imaging condition, and the like are read by a portable barcode reader before imaging. To write to the non-volatile memory. And simultaneously with reading an image with an imaging device, radiation information is read from the said non-volatile memory, and this radiation information is finally added to an image.
According to this method, images and radiation information can always be matched, and when a cassette using a stimulable phosphor is carried to multiple hospital rooms and it is not clear which cassette will be used until shooting, the captured image It is effective to match the radiation information after imaging.

JP-A-6-202254

  However, in the method described in Patent Document 1 or the like, when a lot of information is necessary as radiation information, the photographer or the like needs to read the information by a barcode reader correspondingly. The larger the number, the greater the load on the photographer, which is very inconvenient.

Therefore, the present invention has been made to eliminate the above-described drawbacks, and it is possible to easily, efficiently, and reliably match a captured image with information related to the shooting (shooting information). An object is to provide a photographing apparatus, a photographing system , a photographing method, and a program .

An imaging apparatus according to the present invention is a portable imaging apparatus that acquires captured image data by an X-ray imaging unit that receives an X-ray generated from an X-ray generation unit, and includes a communication unit that acquires imaging information wirelessly. wherein the communication means, wherein the captured image data, and wherein the benzalkonium to send information including the photographing conditions of the X-ray generation unit corresponding to the captured image data wirelessly.

At the time of imaging, an imaging region and imaging conditions are set based on imaging information acquired from the portable storage medium, and imaging is performed based on this setting.
Immediately after shooting, shooting information (patient information, shooting site, shooting conditions, etc.) is added to and stored in the shot image data, and information is added via a communication medium such as a network after all shooting is completed. Transfer the later shot image data. Also, the end of shooting is notified to the predetermined information management side by transferring shooting information.
Further, instead of using a portable storage medium, acquisition of photographic information and transfer of photographic images and photographic information may be performed by wireless communication or the like.
