PROBLEM TO BE SOLVED: To develop an implement to reduce or exclude risk not to be displayed in an image pickup method by including a process for repeatedly obtaining data concerning the plurality of flat layers of a patient between invasions, executing analysis concerning in which one of layers the tip of the implement is positioned and generating a signal to display the layer. SOLUTION: While a doctor inserts a piercing needle 1 to a patient body, an X-ray CT device analyzes continuous data corresponding to the layers 51, 52 and 54, 55 and/or the re-constituted image of the layers concerning in which one of the layers 51 and 55 the tip of the piercing needle 1 is positioned and creates the signal for displaying the layer. Then the tomographic image of the corresponding layer is re-constituted or displayed. When the signal displays the layer being different from the one which is displayed at present, the tip of the needle 1 is separated from the center layer 53 and positioned in the other layers 51, 52, 54 or 55. Then the corresponding layer is re-constituted in place of the layer 53 and the layer is displayed in place of the tomographic image of the layer 53. |
