Description

  The present invention relates to an inspection apparatus, an information processing method, and a program.

In recent years, hospital information systems using network connections have been constructed in hospitals. For example, if it is determined that X-ray imaging is necessary, an inspection instruction is input from a HIS (Hospital Information System) terminal and transmitted to the radiation department as a request destination. This request information is called an examination order, and this examination order includes the department name of the request source, examination items, patient personal data, and the like. When the radiation department receives the inspection order, it adds imaging conditions and transfers it to the X-ray inspection system. The X-ray inspection system performs X-ray imaging according to the received inspection order. Inspection information is given to the photographed image, and transfer to PACS (Picture Archiving and Communication Systems) and print output are performed.
The information given to the transferred image may include patient direction information. The patient direction is represented by two values indicating the anatomical direction of the transverse axis and the longitudinal axis.
Anatomical directions are A (anteria: front), P (posterio: back), R (right: right), L (left: left), H (head: head), F (foot: foot) Indicated by letters. Each value of the direction attribute is expressed in a form including at least one of these characters. For example, in the case of an image in which a person is viewed from the front, the horizontal axis is L (left: left), the vertical axis is the direction of F (foot: foot), and the patient direction is expressed as L ¥ F.
Usually, information on the patient direction is determined in advance for each imaging region, and is output with the patient direction set in advance in the captured image.

  Since the patient direction is determined in advance, when photographing is performed in a direction different from the determined direction, it is necessary to correct the patient direction information to be given or the image itself. When the patient direction information to be given is corrected, there will be images with different orientations regardless of the same part to be imaged. , It will put an extra load on the verifier. Therefore, it is desirable that all images of the same part are unified in the same direction.

  The present invention has been made in view of such problems, and an object thereof is to unify all images of the same part in the same direction.

  Therefore, the present invention is a medical examination apparatus that displays a captured image of a patient and patient direction information indicating a preset direction of the patient associated with the captured image on a display device. A display unit; a patient direction changing unit that changes the direction indicated by the patient direction information displayed on the display device to the indicated direction when instructed to change the direction indicated by the patient direction information; and the patient When the direction indicated by the direction information is changed, the changing unit changes the direction of the captured image associated with the patient direction information to the direction indicated by the patient direction information before the change, and the changing unit sets the direction. And an output means for outputting the photographed image changed.

  According to the present invention, all images of the same part can be unified in the same direction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram illustrating an example of a functional configuration of a medical examination system.
Reference numeral 101 denotes an inspection order input unit for inputting an inspection order. The examination order includes patient information to be photographed and photographing contents. There are a method of inputting an inspection order from an external system such as RIS and a method of inputting manually from a medical inspection system.
Reference numeral 102 denotes a storage unit that stores shooting protocol information for shooting in a storage device. The protocol information is information such as an ID assigned to each protocol, an examination site, and a patient direction. A protocol ID is instructed in an inspection order input from another system such as RIS. Detailed information attached to the protocol is held by the medical examination system.
Reference numeral 103 denotes an image input unit that inputs a radiographic image captured by a digital X-ray imaging apparatus to a medical examination system. The radiation image may be input via a network or may be input via a medium such as a CD-ROM or DVD.
An image holding unit 104 holds an input radiation image in a storage device such as a hard disk. The input image is stored in association with the protocol information.
A display unit 105 displays a radiation image and examination information on a display device such as a CRT or a liquid crystal monitor.
Reference numeral 106 denotes an operation input unit that inputs an operation (operation information) from a mouse, a keyboard, or the like that gives an instruction such as a rotation operation or an inspection end to the radiation image or inspection information displayed on the display device.
Reference numeral 107 denotes an image rotation processing unit that rotates a captured image.
Reference numeral 108 denotes a patient direction information change processing unit that changes patient direction information given to a captured image.
An image rotation control unit 109 controls the image rotation processing unit 107 to perform image rotation processing when the patient direction is changed by the patient direction information processing unit.
Reference numeral 110 denotes an image output unit for transferring an image and inspection information to the outside.
A system bus 111 connects the units 101 to 110 to each other.

  1 may be implemented by hardware, or may be implemented by software realized by the CPU executing a program stored in the memory. Moreover, the medical examination system may be comprised from several apparatus (computer), and may be comprised by one apparatus (computer). In this specification, the medical examination system is composed of one device (computer), and the function shown in FIG. 1 is executed by the CPU of the device (computer) executing a program stored in the memory. The description will be made assuming that it is realized.

Next, the operation of the medical examination system in the present embodiment will be described using the flowchart shown in FIG. FIG. 2 is a flowchart for explaining the operation (information processing) of the medical examination system. In the following, for simplification of description, the description will be made assuming that the CPU performs processing.
In step S201, the CPU inputs an inspection order. There are cases where the input is made from an external system and cases where the input is made from a medical examination system by manual operation.
In step S202, the CPU reads protocol information from the storage device via the protocol information storage unit 102 based on the protocol ID included in the inspection order. This protocol information includes patient direction information.
In step S203, imaging is performed regarding the protocol included in the examination order, and the CPU inputs an X-ray image to the medical examination system. The input image is stored via the image storage unit 104.
In step S204, the CPU displays the image input in step S203 on the display device.
In step S205, the CPU displays patient direction information included in the protocol information read in step S202. The patient direction information is displayed as a character string or an icon.

In step S206, the CPU determines whether a patient direction change operation has been instructed. When determining that the patient direction changing operation has been instructed, the CPU performs a patient direction changing process in step S207. However, the CPU retains the information read via the protocol information storage unit 102 as original information, changes the patient direction information for change processing, and then returns to step S204. Thereafter, in step S205, the CPU displays the changed patient direction.
If it is determined in step S206 that the patient direction changing operation has not been instructed, the CPU proceeds to step S208 to determine whether an examination end instruction has been issued. When determining that the end of the inspection is not instructed, the CPU proceeds to step S209 to perform other processes. The other processing here refers to processing performed before the end of the inspection, such as an operation of enlarging / rotating the image or editing of inspection information.
If it is determined in step S208 that the end of inspection has been instructed, the CPU proceeds to step S210. In step S210, the CPU compares whether the original patient direction and the patient direction for change processing are the same, and determines whether the patient direction has been changed by the end of the examination. If it is determined that the patient direction has been changed, the CPU proceeds to step S211. In step S211, the CPU rotates the image so that the changed patient direction is the same as the original patient direction.
In step S212, the CPU outputs an image and inspection information. The patient direction included in the examination information to be output is not changed, but is the original patient direction information stored via the protocol information storage unit 102.

FIG. 3 is a diagram illustrating an example of an image displayed on the display device and a patient direction. Reference numeral 301 denotes a captured image input from the image input unit 103. Reference numeral 302 denotes the patient direction of the imaging protocol stored via the protocol information storage unit 102. Here, the patient direction is displayed as an icon. This icon may be text information or may be changed to a shape suitable for each photographing protocol.
The patient direction is not automatically discriminated from the image, and is not given by looking at the image after photographing. The patient direction is preset before imaging. Pre-set before shooting and take all images in the set direction. By doing so, the same imaging region can be displayed in the same direction at the time of display.
If it is before photographing, an image is not displayed on 301, but only 302 is displayed as information of a photographing protocol to be photographed from now on, and can be used as a photographing guideline.

  FIG. 4 is a diagram illustrating an example of a GUI that performs an operation on a displayed image and a patient direction. Reference numeral 401 denotes a rotation button that instructs a rotation operation on the display image 301. Reference numeral 402 denotes a patient information rotation button for instructing rotation of the displayed patient direction information. The patient direction rotation button 402 is an example of an object. Reference numeral 403 denotes an inspection end instruction button for instructing the end of the inspection. When the examination end instruction button is pressed, an image output process is performed. Image output is a process of transferring image data and inspection information to another image storage system. 404 is patient direction information. The medical examination system may display the patient direction information 404 in a coordinated manner for confirmation after imaging.

FIG. 5 is a diagram illustrating how the patient direction information is output when the rotation is performed.
A photographed image 501 in FIG. 5A is photographed in a direction different from the preset patient direction 502. Therefore, when the patient direction is rotated by the patient direction rotation button 402, the patient direction information is changed as indicated by 503 in FIG. When the inspection is completed in this state, the output image is automatically rotated and output at an angle preset in this imaging protocol as indicated by reference numeral 504 in FIG. At that time, the patient direction information is also output in the original state. In such a case, the medical examination system may output information and examination information by giving information that patient information has been changed.

FIG. 6 is a diagram showing information stored via the protocol information storage unit 102.
The ID information 601 is a unique value assigned for each photographing protocol.
The protocol name 602 is a name representing a specific imaging region, and is also used for display on the GUI.
Reference numeral 603 denotes patient direction information. The orientation in which this protocol is taken is set in advance.
Reference numeral 604 denotes examination site information. An optimal part is set from a predetermined definition word to which part this protocol belongs.
Usually, since only the protocol ID is instructed in the examination order input from the external system, imaging is performed using information stored in advance in the medical examination system for patient direction and examination site information.

<Embodiment 2>
Although the first embodiment is limited to the case where the rotation operation is performed, the image can be similarly converted and output in accordance with the patient direction even in the reversing operation.
