  2. Description of the Related Art In recent years, X-ray imaging apparatuses (radiation imaging apparatuses) using large-sized solid-state imaging devices that can cover the size of a human body, so-called flat panel detectors, have been developed due to advances in semiconductor technology. In such an X-ray imaging apparatus, since an X-ray image obtained by imaging is displayed for several seconds, it is possible to immediately determine whether or not imaging has been appropriately performed, and efficient imaging can be performed. ing.

  On the other hand, with the development of an information network in a hospital, hospital information systems (Hospital Information System: hereinafter referred to as “HIS”), radiation information systems (Radiology Information System: hereinafter referred to as “RIS”) are systems that handle information on the network. And information storage systems such as Image Archiving and Communication Systems (hereinafter referred to as “PACS”) have been developed and are closely related to the operation of X-ray imaging apparatuses.

  The HIS deals with all of hospital management information such as patient information (for example, patient ID, patient name, gender, age (and birth date), etc.) and accounting information. RIS receives requests for radiographs from clinical departments, manages the information related to image radiographing, such as clarifying which part of a patient is to be radiographed and issuing radiographs as examination information. The notification of the start of shooting and the end of shooting is received from the beginning, and the shooting state is managed. The PACS stores X-ray images obtained by imaging, and stores and manages X-ray images such as searching and distributing images when there is a request for visual recognition of past images.

  The X-ray imaging apparatus selects one inspection information from a plurality of inspection information received from the RIS via the network and starts an inspection. Specifically, the X-ray imaging apparatus performs imaging specified by the selected examination information, transmits an X-ray image obtained by imaging to the PACS, and ends the examination.

For example, when the imaging part display unit 731 shown in FIG. 7 is selected and the imaging button 750 is operated by the user, the X-ray imaging control device 1510-1 (for example, the examination start unit 1513-1) actually performs imaging. The chest front is determined as an imaging region. In this embodiment, the user selects the imaging region and determines the imaging region. However, for example, the imaging region is automatically determined according to the order of examination information transmitted from the RIS 1200, for example. May be. It is also possible to change the imaging order of the imaging regions or add an imaging region based on the judgment of a user such as an imaging engineer.

  Subsequently, in step S205, the X-ray imaging control apparatus 1510-1 (for example, the examination start unit 1513-1) performs control for imaging the imaging region determined in step S204. At this time, the X-ray imaging control device 1510-1 (for example, the examination start unit 1513-1) transmits the tube voltage and tube current of the X-ray tube 1530-1 and the X-ray to the X-ray generation device 1520-1. X-ray generation conditions such as irradiation time are transmitted, and X-rays based on the X-ray generation conditions are irradiated from the X-ray tube 1530-1. Further, the X-ray imaging control device 1510-1 (for example, the examination start unit 1513-1) receives an X-ray image based on the X-ray transmitted through the patient as the subject from the X-ray detection device 1540-1, and is necessary. Image processing is performed according to Here, re-photographing may be performed at the discretion of a user such as a photography engineer.

Subsequently, in step S206, the GUI display / operation input unit 1511-1 displays an X-ray image obtained by imaging in step S205. For example, when the front of the chest is imaged as an imaging region, the X-ray image is displayed in the captured image display area 740 shown in FIG. 7, and the thumbnail image is displayed in the thumbnail image display area 731a.
Thereafter, the process proceeds to step S203, and the processes after step S203 are performed.

On the other hand, as a result of the determination in step S203, if an operation input for ending the inspection is made, the process proceeds to step S207.
In step S207, the X-ray imaging control apparatus 1510-1 performs processing for transmitting all the X-ray images acquired by the inspection to the PACS 1300.
Thereafter, the process proceeds to step S101 in FIG. 3, and the processes after step S101 are performed.

If the result of determination in step S203 is that there has been an operation input for suspension of examination, the process proceeds to step S208. For example, in a situation where imaging of a part of the imaging region displayed in the imaging region display area 730 has been completed and imaging of another patient with high urgency has interrupted, the user operates the end button 760. Then, the inspection is put on hold.
In step S208, the examination holding unit 1514-1 puts the examination started by the examination start unit 1513-1 in a pending state, and transmits examination-related information related to the examination in the pending state to the server 1400. Here, as the examination related information, in addition to the examination information of the examination received from the RIS 1200, information on a taken part that is a taken part taken up to the present time, information on a holding source (that is, a holding state and X-ray imaging apparatus 1500 (information of the first X-ray imaging apparatus 1500-1 in this example).

Subsequently, in step S209, the examination suspension unit 1514-1 transmits to the server 1400 an X-ray image of the imaging region that has been imaged until the suspension state.
Thereafter, the process proceeds to step S101 in FIG. 3, and the processes after step S101 are performed.

The list shown in FIG. 9 shows only main items. Management No. Is a number uniquely assigned by the server 1400 so that the held examination can be uniquely identified. The information on the patient ID, patient name, sex, age, imaging region, and imaging region is based on the examination related information of the pending inspection transmitted from each X-ray imaging apparatus 1500. Here, the information on the imaging region is identification information (identification number) such as an anatomical code indicating the imaging region requested from the RIS 1200. Further, the information on the imaged region is identification information (identification number) such as an anatomical code indicating the imaged region that has already been imaged, and includes information on the imaged region that is additionally imaged at the judgment of a user such as an imaging engineer. The information on the hold source is identification information such as the IP address of the X-ray imaging apparatus 1500 that has been put on hold. Here, “192.168.80.3” corresponds to the first X-ray imaging apparatus 1500-1 shown in FIG. 1, and “192.168.8.80.4” corresponds to the second X-ray shown in FIG. It corresponds to the imaging device 1500-2.
In addition, it is assumed that the server 1400 manages the X-ray image in the imaging region, which is transmitted from the examination holding unit 1514 and is taken until the holding state, is associated with the above-described holding examination information.
