Abstract: An absorption target for measuring power of high-intensity focused ultrasound, comprising a container and a cone target cluster. The cone target cluster includes basic units with the same geometrical shape. The upper part of each basic unit is a pyramid, and the lower part of each basic unit is a prismatic base. The vertexes of respective side surfaces of the pyramid converge at a perpendicular bisector of the prismatic base to form a cone vertex and the cross sections of the pyramid and the base are squares, regular triangles or regular hexagons. The bases of the basic units are seamlessly and tightly arrayed at the bottom in the container. Sound waves of an incident cone target cluster to escape into space outside the cone target cluster only in case of at least two reflections or scatterings. Open micropores are densely distributed inside the basic units of the cone target cluster.
