摘要： According to an insertion support system of the present invention, when a biopsy area is specified at a periphery of the bronchi, the barycenter of the biopsy area is extracted. A circle centering on the barycenter is determined as a search area. The search area is expanded until the bronchi are located within the search area. A point in the search area to which the bronchi first reach is determined as an end point. A first route choice connecting the end point and a start point is determined. If the first route choice has not been registered yet, the first route choice is registered as a first registered route. Accordingly, a location of interest can be specified as an arbitrary region, and navigation leading to the specified region is appropriately set.

摘要： A general-light observation light image can be obtained by illuminating the polarized frame sequence light or polarized white light, for example. In addition, a parallel polarized component and a vertical polarized component with respect to a polarizing direction of illuminating light, which is polarized in a specific direction are captured. Then, image data, which is a difference between both of the polarized component is calculated and is displayed in a display device. Thus, a scattered light component in a living-body tissue surface side can be extracted with good S/N, which can improve the diagnosis functionality.
