  2. The ophthalmologic imaging apparatus according to claim 1, wherein the identification information is a graphic symbol.
  3. The ophthalmologic imaging apparatus according to claim 1 or 2, further comprising: an apparatus main body including at least the imaging unit, wherein the user interface is a touch panel display attached to the apparatus main body, and the user interface also serves as a display unit on which the selection screen is displayed.
  4. The ophthalmologic imaging apparatus according to any one of claims 1 to 3, wherein in a case where a selection operation is received, on the selection screen, for the examination selection button on which two or more types of the identification information are arranged, after a screen transitions from the selection screen, two or more imaging operations based on scan patterns corresponding to the identification information are sequentially executed without displaying the selection screen in between.
  5. The ophthalmologic imaging apparatus according to any one of claims 1 to 4, further comprising: a communication unit configured to communicate with outside, wherein in a case where an examination order corresponding to any one of the examination selection buttons is acquired via the communication unit, the examination selection button corresponding to the examination order is selected on the selection screen regardless of the selection operation.
  6. The ophthalmologic imaging apparatus according to any one of claims 1 to 5, wherein after a screen transitions from the selection screen based on the selection operation, a progress status of an imaging operation is displayed using the identification information.
  7. The ophthalmologic imaging apparatus according to any one of claims 1 to 6, wherein after acquiring the OCT data of the subject eye corresponding to each of the two or more types of scan patterns, a list of a plurality of reports generated corresponding to each of the scan patterns is displayed, and identification information corresponding to each report is arranged around each report respectively on a report output screen for receiving a selection operation for a report to be output.
  8. The ophthalmologic imaging apparatus according to any one of claims 1 to 7, wherein on a setting screen different from the selection screen, assignment of the scan patterns corresponding to respective examination selection buttons is set and changed based on an operation input, and wherein on the selection screen, the identification information is arranged on each examination selection button according to the assignment of the scan patterns to respective examination selection buttons.
  9. The ophthalmologic imaging apparatus according to claim 8, wherein the identification information is displayed on the setting screen to indicate each of the scan patterns.

Description

TECHNICAL FIELD The present disclosure relates to an ophthalmologic imaging apparatus. BACKGROUND ART In the related art, ophthalmologic imaging apparatuses such as optical coherence tomography (OCT), fundus cameras, and SLO are widely used in medical institutions and examination facilities (hereinafter collectively referred to as "facilities and the like"). In OCT, an OCT optical system is controlled to scan an acquisition position of a subject eye with measurement light, thereby acquiring a tomographic image of the subject eye as an OCT image. In OCT, one of a variety of scan patterns, such as line scan, cross scan, multi-scan, radial scan, and raster scan, is selected for each examination. A graphical user interface (GUI) is used for an examiner to select the scan pattern. For example, in Patent Document 1, when selecting a scan pattern, a UI element on a screen 500 shown in FIG. 21 is operated. On the screen 500 shown in FIG. 21, a list 510, which is a UI element for selecting a scan pattern, is displayed simultaneously with an observation image (anterior ocular segment observation image 520), a fundus front image 530, and an OCT image 540. In the screen 500 shown in FIG. 21, the anterior ocular segment observation image 520 is used for manual or automatic alignment adjustment. On the screen 500, a UI element 550 for setting scan parameters, a UI element 560 for manual adjustment of the optical system, an optimize button 570 for automatic adjustment, a capture button 580, and the like are arranged. That is, UI elements for inputting various operations required from the selection of a scan pattern to the start of capture are arranged on the same screen. In the list 510, a plurality of scan patterns are listed. By selecting a text 510a of the desired scan pattern on the list 510 based on the operation, one of the scan patterns is alternatively selected. A scan line 535 corresponding to the selected scan pattern is displayed on the fundus front image 530. The fundus front image 530 and the scan line 535 allow the scan pattern and a scan position to be confirmed. The OCT image 540 is acquired and displayed in real time at the scan position indicated by the scan line 535. In FIG. 21, two OCT images that form the scan pattern of the cross scan are displayed side by side. The scan line 535 can be moved on the fundus front image 530 in response to an operation, thereby changing the scan position. CITATION LIST PATENT LITERATURE Patent Literature 1: JP2014-90748A SUMMARY OF INVENTION In the screen configuration of the related art described above, it is difficult for an examiner who is unfamiliar with OCT examination to handle the screen because the configuration in one screen is complicated. In addition, among medical institutions and examination facilities (hereinafter, collectively referred to as "facilities and the like"), there are many facilities and the like in which examinations are performed on most subjects by using only a few examination patterns (combinations of one or more scan patterns). In such a facility, it is desirable to be able to efficiently perform examinations using a few predetermined examination patterns with a simpler procedure. The present disclosure has been made based on at least one of the problems of the related art, and a technical object of the present disclosure is to provide an ophthalmologic imaging apparatus that easily improves examination efficiency. An ophthalmologic imaging apparatus according to a first aspect of the present disclosure includes: an imaging unit including all or a part of an OCT optical system configured to scan tissue of a subject eye with a plurality of scan patterns; a user interface configured to receive an operation input by an examiner; and a controller configured to display, on a selection screen, a plurality of examination selection buttons corresponding to a preset examination pattern, receive a selection operation for any of the examination selection buttons on the selection screen, after receiving the selection operation, transition the display to a second screen on which an observation image is displayed and for adjusting an apparatus state, and execute an examination after passing through display of the second screen, in which identification information indicating a type of the scan pattern is arranged on the examination selection button, and two or more types of the identification information corresponding to two or more scan patterns are arranged on at least one of the examination selection buttons, and in a case where an examination is started as the examination selection button on which two or more types of the identification information are arranged is selected, the controller scans a subject eye with each scan pattern corresponding to the two or more types of the identification information to sequentially acquire OCT data of the subject eye corresponding to each scan pattern.
