A medical image display control device visualizing a tubular tissue in
volume data to perform operations comprising: path acquisition means for
acquiring a path along the tissue; first range specifying means for
accepting user specification of a specified range of the path; first
display control means for visualizing the tissue, and for indicating the
positions of relatively fixed to the window; first setting means for
setting cross-sectional planes crossing the path corresponding from the
positions; second display control means for visualizing each
cross-sections of the tissue by the planes; second range specification
means accepting a new specification of a range of the path; third display
control means for visualizing the tissue, and for indicating the
positions of relatively fixed to the window; second setting means for
setting new planes crossing the path corresponding to the positions; and
fourth display control means for visualizing each cross-sections of the
tissue by the new planes.
