The display calculation device 110 shown in FIG. 2 is a diagram showing the display calculation device 110 in the medical image diagnostic apparatus 100 shown in FIG. 1 in more detail. The display arithmetic device 110 includes a video converter 110a, a capture 110b, and an image memory 110c. The display layouts shown in FIGS. 3 (a) to 3 (c), 5 (a), and 5 (b) are displayed based on the imaging operation status of the X-ray diagnostic unit 101 and the endoscope 102, respectively. 3 is an example of a display layout displayed on the device 111. FIG. FIG. 4 is a table showing the relationship between the X-ray fluoroscopic image displayed on the display device 111 and the display layout of the endoscopic image based on the imaging operation status by the X-ray diagnostic unit 101 and the endoscope 102.

  In the medical image diagnostic apparatus 100 of the present embodiment, the X-ray fluoroscopic image captured by the X-ray diagnostic unit 101 of the medical image diagnostic apparatus 100 is displayed as the X-ray fluoroscopic image signal 200 from the X-ray image processing unit 108. To the video converter 110a. Similarly, an endoscope image photographed by the endoscope 102 is transmitted from the endoscope 102 to the video converter 110a in the display arithmetic device 110 as an endoscope image signal 201.

  The imaging operation status by the X-ray diagnosis unit 101 and the endoscope 102 is grasped by the control unit 113. Similarly, it is possible to determine the shooting operation status by the video converter 110a. That is, the video converter 110a performs imaging and endoscopy by the X-ray diagnostic unit 101 depending on the presence or absence of the X-ray fluoroscopic image signal 200 and the endoscope image signal 201 transmitted from the X-ray image processing unit 108 and the endoscope 102. It is determined whether shooting by the mirror 102 is currently being performed. For example, when the X-ray fluoroscopic image signal 200 is received by the video converter 110a, it means that the X-ray fluoroscopic imaging by the X-ray image processing unit 108 is being performed.

  Based on the X-ray diagnosis unit 101 and the information on the imaging operation status by the endoscope 102 transmitted from the control unit 113 to the video converter 110a, the video converter 110a displays the display sizes of the X-ray fluoroscopic image and the endoscopic image, respectively. The display position is determined, and a composite image signal for displaying them on one screen is generated. The display size and display position of the X-ray fluoroscopic image and endoscopic image determined by the video converter 110a are selected from the display layouts registered in the video converter 110a in advance. In addition, the video converter 110a sends an image signal to which the display size and display position information are added to the capture 110b. The image signal sent to the capture 110b is converted into a file format. Details will be described later in Example 2. The generated composite image signal is sent to the image memory 110c, and is sent from the image memory 110c to the display device 111. The display device 111 performs display based on the composite image signal sent from the image memory 110c.

Next, the display layout will be described in detail.
FIGS. 3A to 3C show the display layouts of two images displayed on one screen. In FIG. 3A, the image A is displayed on the left side of the display screen and the image B is displayed on the right side of the display screen with the same size (hereinafter referred to as display layout 0). In FIG. 3 (b), image A is displayed on the left of the display screen, image B is displayed on the right of the display screen, and the display size of A is displayed larger than the display size of B (hereinafter referred to as the display). Called Layout 1). In FIG. 3 (c), image A is displayed on the right of the display screen, image B is displayed on the left of the display screen, and the display size of A is displayed smaller than the display size of B (hereinafter referred to as the display). Called Layout 2). An image A in FIGS. 3A to 3C is an X-ray fluoroscopic image, and an image B is an endoscopic image. The combination of the imaging operation status of the X-ray diagnosis unit 101 and the endoscope 102 and the display layout of the X-ray fluoroscopic image and the endoscopic image shown in FIG. 4 is merely an example.

  Case 1 shown in FIG. 4 is a case where imaging by the X-ray diagnostic unit 101 and imaging by the endoscope 102 are both stopped (indicated as OFF in the figure). In this case, the video converter 110a controls the display layout displayed on the display device 111 to be the display layout 0 based on the imaging operation status of the X-ray diagnostic unit 101 and the endoscope 102. For example, the display layout 0 is used for the initial screen of the display device 111 before imaging by the X-ray diagnostic unit 101 and the endoscope 102. On the initial screen, the image A and the image B may be displayed only with a fluoroscopic image, an endoscopic image, and textual notation, respectively. As a result, the operator can quickly determine which image comes to which position. Further, in the case of the first embodiment, the display layout 0 is used in the case 1, but when both the imaging by the X-ray diagnostic unit 101 and the imaging by the endoscope 102 are stopped, another imaging device such as an indoor camera or An image from a camera or the like that images the subject may be displayed on the display device 111 as an image C (not shown) together with the images A and B, or only the image C may be displayed on the display device 111.

  Case 2 shown in FIG. 4 is a case where only imaging by the X-ray diagnostic unit 101 is performed (denoted as ON in the figure). In this case, the video converter 110a controls the display layout displayed on the display device 111 to be the display layout 1 based on the imaging operation status of the X-ray diagnosis unit 101 and the endoscope 102. For example, when the operator wants to move the endoscope 102 to a desired position inside the subject 103, the display layout 1 is used to display on the display device 111.

  Case 3 shown in FIG. 4 is a case where only photographing with the endoscope 102 is performed. In this case, based on the imaging operation status of the X-ray diagnostic unit 101 and the endoscope 102, the video converter 110a performs control so that the display layout displayed on the display device 111 is the display layout 2. For example, when the endoscope 102 reaches a desired position inside the subject 103 by the operator and photographing with the endoscope 102 is performed, the display layout 2 is used to display on the display device 111.

  Case 4 shown in FIG. 4 is a case where imaging by the X-ray diagnostic unit 101 and imaging by the endoscope 102 are both performed. In this case, the video converter 110a controls the display layout displayed on the display device 111 to be the display layout 1 based on the imaging operation status of the X-ray diagnosis unit 101 and the endoscope 102. For example, when the operator reaches the desired position inside the subject 103 by the operator and takes an image while moving the endoscope 102 inside the subject 103, the display device using the display layout 1 is used. Display on 111.

  In addition, when the case 2 shifts to the case 3, that is, when the radiographing by the X-ray diagnostic unit 101 is changed from the execution state to the stop state, the X-ray fluoroscopic image last displayed on the display device 111 is a still image. Thus, the display layout of case 3 can be shifted to. When performing imaging with the endoscope 102, the operator can grasp in which part of the subject 103 the endoscope 102 is located.

  The display layout to be displayed based on the imaging operation status by the X-ray diagnosis unit 101 and the endoscope 102 can be registered with several patterns before product shipment, or set in advance by the operator. You can also.

  As described above, according to the medical image diagnostic apparatus 100 of the present embodiment, the X-ray diagnostic unit 101 automatically captures the X with the display layout desired by the operator based on the operation status of imaging by the X-ray diagnostic unit 101 and imaging by the endoscope 102. A fluoroscopic image and an endoscopic image can be displayed on the display device 111. As a result, it is possible to reduce the load on the operator during photographing.

  The display layout shown in this example is one example, for example, the display layout 0 shown in FIG. 5 (a) (the same display layout as FIG. 3 (a)) and the display layout shown in FIG. 5 (b). The display in which only the display positions of the image A and the image B are switched may be switched according to the operation state of the imaging by the X-ray diagnostic unit 101 and the imaging by the endoscope 102. Further, in this embodiment, the case of a combination of imaging by the X-ray diagnostic unit 101 and imaging by the endoscope 102 has been described, but a combination of imaging by the ultrasound imaging apparatus and imaging by the endoscope 102, etc. It goes without saying that it can also be used.
