2. Description of the Related Art FIGS. 7 and 8 show a console in a conventional X-ray imaging apparatus. FIG. 7 is a perspective view showing the entire console, and FIG. 8 is an enlarged view of an operation panel and a display panel of the console. It is a top view. FIG. 8 includes an embodiment of the present invention described later. The console includes a support base 60, a support plate 61 supported by the support base, and an operation display panel 62 attached to a tip of the support plate 61. The operation display panel 62 incorporates an anatomical program for controlling the X-ray control device (Medical and Dental Publishing Co., Ltd .: Radiation Diagnostic Equipment Engineering, Medical Radiation Science Course 13, P108, 4.4 Program photographing function). On the surface of the operation display panel 62, there are provided an operation panel 70 having a touch button for operating the program, a touch button for setting imaging conditions and emitting X-rays, and the like. The display panel 71 displays an imaging part of the subject by operating the imaging part, and displays an imaging part and imaging conditions of desired details by touching a button of a selected part among the imaging parts. Is made up of When the operator performs X-ray imaging, the user presses the upper button of the program page button 701 on the touch panel 70 to display the first imaging region (for example, skull, chest, abdomen, dorsal column, upper limb, etc.) on the display panel 71. Display in the form of a table. Next, the operator selects a second imaging part from the first imaging parts. For example,
When the first imaging region is the skull, pressing the touch button indicated as skull causes the display panel 71 to display a second imaging region indicating the details of the skull {for example, the skull by the action of the anatomical program. (Back front), skull (side surface), skull (axial direction), mandible (back front), sinus (back front), etc. are displayed. The operator selects a part to be imaged from the second part to be imaged, and presses a portion (touch-type button) where the selected part is displayed.
