First, the three-dimensional scanner 100 generates (or acquires) three-dimensional scanning data by three-dimensionally scanning the body part corresponding to the affected part or the affected part of the patient.

In addition, the controller 500 displays a three-dimensional image (or three-dimensional image information) according to the generated (or obtained) three-dimensional scanning data on the display unit 300.

For example, as shown in FIG. 3, the three-dimensional scanner 100 scans the hand including the index finger of the patient three-dimensionally.

Also, as shown in FIG. 4, the 3D scanner 100 merges (or integrates) the data according to the three-dimensional scanning to generate three-dimensional scanning data.

In addition, the control unit 500 displays a three-dimensional image (for example, a hand including the index finger of the patient) according to the generated three-dimensional scanning data on the display unit 300 (S210).

Thereafter, when a specific region is selected from the three-dimensional images displayed on the display unit 300, the control unit 500 selects objects in the selected specific region.
