  Generally, in a medical imaging apparatus, a medical examination is performed on a subject and a medical image related to the subject is acquired. In the medical image display device, image processing, browsing, and the like are performed on the medical image acquired by the medical image imaging device. The medical image capturing apparatus and the medical image display apparatus basically execute processing independently of each other. For this reason, information is not sufficiently shared between the medical image capturing apparatus and the medical image display apparatus.

  For example, an imaging protocol indicating a procedure for performing a medical examination on a subject is created in the medical imaging apparatus. The medical imaging apparatus performs a medical examination on the subject according to the imaging protocol. However, since the medical image capturing apparatus and the medical image display apparatus execute processing independently of each other, the imaging protocol creation process in the medical image capturing apparatus does not affect the process in the medical image display apparatus. is there.

  On the other hand, in the medical image display device, the layout of the medical image on the display screen for displaying the medical image is set. The medical image display device displays a medical image according to the set layout of the medical image. However, since the medical image capturing apparatus and the medical image display apparatus execute processing independently of each other, the setting process related to the layout of the medical image in the medical image display apparatus does not affect the process in the medical image capturing apparatus. There is nothing.

  FIG. 5 is a sequence showing a flow of operations of the medical image diagnostic apparatus 1 according to the present embodiment. FIG. 5 shows a processing flow in the medical image display device 2 and the medical image imaging device 3 until a browsing screen related to a medical image is set before imaging starts and a medical image is displayed on the set browsing screen. .

  In step SF1, the display circuit 23 of the medical image display device 2 displays a setting screen for a browsing screen related to medical images before imaging starts. For example, the display circuit 23 displays a graphic user interface (Graphical User Interface, hereinafter referred to as GUI) capable of executing a setting operation related to the layout of the medical image as a setting screen of the browsing screen related to the medical image.

  FIG. 6 is a diagram illustrating an example of a GUI displayed on the display circuit 23 when the layout of the browsing screen is set. On the display screen D1 of the display circuit 23, a setting screen for a browsing screen related to a medical image is displayed.

For example, the operator operates the pointer P via the input IF circuit 21 and drags and drops the icon displayed in the display area AG into the layout area AL. Thus, a display area for displaying a medical image is set in the layout area AL. Specifically, a “two-dimensional non-contrast axial sectional image” of “slice thickness: 5.0 mm” obtained by imaging the “head” of the subject S is displayed in the layout area AL as “window width: 80” and “window level”. : 35 ”is set as the display area AL1.

When a setting operation related to the image quality of a medical image is input, the processing circuit 26 determines a layout parameter related to the image quality of the medical image that has been set.

  The process of determining the layout parameter based on the setting operation is repeated until a confirmation operation for the viewing screen by the operator is input (steps SF3 and SF4). By repeating the above processing, the medical image display apparatus 2 creates a browsing screen related to medical images. In addition, layout parameters relating to medical images on the created browsing screen are determined. The browsing screen and the layout parameters are stored in the storage circuit 24.
