Description

  The present invention relates to a medical examination system, and more particularly to a medical examination system and an X-ray imaging apparatus for inputting patient information and proceeding with an examination.

In hospitals and clinics, examination information is exchanged between the upstream system and the X-ray imaging system. As the upstream system, there is a hospital information system called HIS (Hospital Information System) or a radiation information system called RIS (Radiology Information System).
Since these systems, including the X-ray imaging system, are made by multi-vendors, if each vendor develops a system with its own specifications, it can be connected to the RIS of vendor A, but the RIS of vendor B Can not be connected, and it is necessary to develop a unique specification for each vendor. In order to deal with such common use of medical information, the DICOM (Digital Imaging and Communications in Medicine) standard shown in Non-Patent Document 1 was created as a standard for image information communication and storage independent of vendors. In the DICOM standard, an image format, a communication procedure and method, a standard for storing on a medium, and the like are defined.

Digital Imaging and Communications in Medicine (DICOM)

  In actual sites, there are many RISs that transmit inspection information that does not conform to the DICOM standard format. When the X-ray imaging system receives so-called illegal data that does not conform to the format from the RIS, it is necessary to notify an error indicating that the illegal data has been received. On the other hand, when shooting efficiency is required, especially in the case of emergency shooting, notification of errors is troublesome, and shooting efficiency may be hindered. There are various levels of illegal data, ranging from a serious level where the inspection cannot be performed to a level which does not affect the inspection.

In order to solve the above problems, the present invention
Inspection information receiving means for receiving inspection information from the RIS;
Inspection information determination means for determining whether or not unauthorized data is included in the inspection information acquired by the inspection information acquisition means;
An inspection impossibility error storage means for storing a list of errors that cannot be inspected;
An error display means for displaying an illegal data reception error;
An executable inspection determination unit that compares the data determined to be invalid by the inspection information determination unit with the error list stored by the inspection impossibility error storage unit;
An error display suppression unit that suppresses display of a reception error by the error display unit with respect to an error determined to be executable by the executable test determination unit;
It is characterized by having.

  According to the present invention, an error is not displayed even if illegal data having a level that does not affect the inspection performance is received. Therefore, the operability of the X-ray imaging system is improved for a user who does not need to display an error when receiving illegal data at a level that does not affect the inspection.

It is a block diagram of the medical test | inspection system in embodiment. It is a flowchart which shows the process sequence at the time of the input from RIS in embodiment. The example of the test | inspection information received from RIS is shown. An example of DICOM convention violation data that is not subject to error display suppression is shown. The example of the DICOM rule violation data used as error display suppression object is shown. An example of an error displayed when receiving DICOM rules violation data An example of a setting UI for error display suppression will be shown.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

<Description of system configuration>
FIG. 1 is a diagram showing a configuration of an X-ray imaging system.

  The X-ray imaging system includes a sensor unit 1002 including an X-ray tube 1000, an X-ray generator control unit 1001, an X-ray imaging system display unit, an X-ray imaging system operation unit, and a sensor 1003. The X-ray imaging system control unit 1009 processes a digital image signal obtained from the imaging unit and performs various controls on the X-ray generator. Also, it functions as a management device that manages the order of radiation imaging received from the outside.

  The X-ray generator control unit 1001 controls application of a high voltage to the X-ray tube 1000 according to imaging conditions such as tube current, tube voltage, and irradiation time sent from the X-ray imaging system control unit 1004. And control the generation of X-rays. The RIS 1005 holds an examination list and can send examination information to the X-ray imaging system. A PACS (Picture Archiving and Communication System) 1006 can receive an inspected image sent from the X-ray imaging system control unit.

  The X-ray imaging system operation unit 1007 can input patient information and make various system settings.

  The operation performed by the user through the X-ray imaging system operation unit 1007 is received by the X-ray imaging system control unit, and the processed result is reflected in the X-ray imaging system operation / display unit.

  The inspection information control unit includes a reception unit 10091, a determination unit 10093, a storage unit 10093, and a comparison unit 10094. The inspection information control unit also functions as a classification unit that classifies information that does not conform to the DICOM standard into at least one of a plurality of error levels.

  The inspection information receiving unit 10091 can acquire inspection information from the RIS 1005.

  The examination information determination unit 10092 functions as a standard determination unit that determines whether the acquired radiation examination information includes information that does not comply with the DICOM standard based on the DICOM standard. Accordingly, the examination information determination unit 1009 can determine whether the examination information acquired from the RIS 1005 by the examination information reception unit 10019 is illegal data. Violation of DICOM rules is one of the indicators of whether inspection information is illegal. For example, when “030Y” must be entered in the age, but “30Y” is entered, it is a violation of the DICOM rules. Another example is when the StudyInstanceUID is empty. The StudyInstanceUID is an indispensable item and cannot be inspected if it is empty.

  The inspection information storage unit 10093 holds a list of errors that cannot be inspected.

  The inspection information comparison unit 10094 functions as a type determination unit that determines whether information that does not comply with the DICOM standard classified into a specific error level falls under a predetermined type. As a result, the inspection information comparison unit 10094 can compare the illegal data with the error list held by the inspection information storage unit.

  The X-ray imaging system display control unit 1010 can control the display of a DICOM protocol violation data reception error.

<Description of overall processing>
FIG. 2 is a flowchart of the medical examination system. The X-ray imaging system is started, and the X-ray imaging system display control unit makes a transition to the examination list screen in S2001. In step S2002, the inspection information receiving unit 10091 receives inspection information. In step S2003, the inspection information determination unit determines whether the received inspection information is data that violates DICOM rules.

  If the data does not violate the DICOM protocol, the X-ray imaging system control unit performs an inspection in S2011. If the data is in violation of DICOM rules, the inspection information control unit classifies the error level in S2004. There are three error level classifications: FATAL, ERROR, and WARNING. FATAL indicates a state in which photographing cannot be continued such that the sensor does not react. ERROR indicates a state such as a DICOM communication error that requires some action by the user and should be taken. “WARNING” refers to a state where the user does not need to respond immediately, such as when the sensor temperature is slightly high. The error level of DICOM convention violation data is classified as ERROR.

  In step S2005, the inspection information control unit registers the error content in the error history. In step S2006, the inspection information comparison unit 10094 acquires a list of errors that cannot be inspected from the inspection information storage unit 10093. In step S2007, the inspection information comparison unit compares whether the error content is included in an error list that cannot be inspected.

  If the error content is included in the error list that cannot be inspected, the X-ray imaging system display control unit 1010 instructs the X-ray imaging system display unit to display an error, and the X-ray imaging system display unit 1008 displays an error in S2008. To do.

  If the error content is not included in the error list that cannot be inspected, the X-ray imaging system display control unit checks the error display suppression setting in S2009. If the error display suppression is off, the X-ray imaging system display unit displays an error in S2010. If the error display suppression is on, no error is displayed and the X-ray imaging system control unit performs an inspection in S2011.

  In S2012, the inspection information control unit confirms whether the input-required item is not input. If it is not entered, the inspection ends. If not input, the X-ray imaging system display unit displays an input dialog in S2013. For example, there is a case where the age is set as an input-required item, and the inspection is finished while the age of the received inspection information is replaced with empty due to violation of DICOM rules.

<Description of display screen>
FIG. 3 is an example of examination information received from the RIS. In FIG. 3, patient ID, patient name, age, sex, and StudyInstanceUID are listed, but other information such as date of birth and receipt number may be included.

  FIG. 4 is an example of inspection information that is a violation of the DICOM protocol that is subject to error display suppression. In FIG. 4, since an invalid value is included in the age, it is replaced with a blank.

  FIG. 5 is an example of inspection information that is a violation of the DICOM protocol that is not subject to error display suppression. In FIG. 5, since the StudyInstanceUID that is essential for identifying the examination is empty, an error is displayed.

  FIG. 6 shows an example of a UI for receiving an examination list and a screen displayed when invalid data is received on this screen. When a list update is pressed on the examination list screen, examination information is acquired from the RIS. If the acquired examination information contains invalid data, an error dialog with a title, message, and confirmation button is displayed. When the confirmation button is pressed here, the error dialog is hidden. This error dialog is not displayed as shown in the sequence shown in FIG. 2 when error display suppression is on and the error cannot be checked.

  FIG. 7 is an example of a setting UI for error display suppression. Checking the check box for displaying an error when the received data is invalid in the MWL setting and pressing the OK button turns on error display suppression.

  In the present embodiment, the DICOM protocol is used as an index for determining whether or not the data is illegal, but it is also possible to set other indexes.

  In this embodiment, as an error that is an error display suppression target, the case where an illegal value was included in the received tag was given, but when there is a character string that is not included in the character set as another example, A case where a date before 1753 is included.

  In the present embodiment, the case where the StudyInstanceUID is empty is given as an error that is not subject to error display suppression. However, as another example, there is an association error when an essential item such as a patient ID is empty.

  In the present embodiment, the examination list screen is given as the UI when illegal data is received. However, as another example, after inputting examination information and photographing as an emergency patient, the RIS examination information and the emergency patient are displayed. A screen that links information.

  Further, since the computer program is normally stored in a computer-readable recording medium such as a CD-ROM and can be executed by copying or installing the computer program in a system, such a computer-readable storage medium also falls within the scope of the present invention. .
