超音波診断支援のためのメンタルローテーション能力の可視化

抄録

Echography is inexpensive and indispensable equipment in every medical field but examination with Echography greatly need the expertise and experience of an operator. So, person who is not skill in echography not easy inspect. We have constructed an echography support system for reducing the burden of doctor and patient so far. We estimated the mental rotation matrix by focusing on the echogram change and probe movement. We focused on the acoustic window can be taken clear images avoiding bones and organs. Also, experts have focused on placing probes on the acoustic window and have been working on building probe contact position and orientation measurement systems. We set a region of interest called ROI in the obtained echogram, and analyzed the average luminance value in the region. In this paper, we report estimation and measurement of the probe movable range which acquires only the acoustic window by combining the analysis result of the average luminance value with probe contact position information. We propose system for examination acoustic window by estimating range of motion of probe for examination with desired echography.
