Claim 0:
1. A puncture support device comprising processing circuitry configured to:
acquire three-dimensional volume data;
set a puncture target in the volume data;
set puncturable regions on an image including a body surface of a subject and the puncture target in the volume data, the puncturable regions existing on the body surface, each of the puncturable regions on the body surface being set within a circle centered on the puncture target and whose radius is a depth at which a puncture needle used is puncturable;
extract linear puncture routes of each of the puncturable regions, the linear puncture routes each being from each point of the puncturable regions on the body surface to the puncture target;
calculate safety degrees of the respective linear puncture routes for each puncturable regions, based on a distance between each of the linear puncture routes and a protection target and on a coefficient of the protection target;
classify the puncturable regions into groups based on the safety degrees of the linear puncture routes for each puncturable regions;
set candidates of puncture insertion points for puncturing the puncture target on puncturable regions classified into a predetermined group of the groups; and
display, on a display, a superimposed image in which an image including the classified puncturable regions, safety degrees of the respective classified puncturable regions, and the candidates on the respective puncturable regions classified into the predetermined group is superimposed on the body surface a body surface image of the subject taken from outside the subject, the body surface image not including an internal structure of the body surface of the subject.
