Absorption target for measuring power of high-intensity focused ultrasound

An absorption target for measuring power of high-intensity focused ultrasound, comprising a container and a cone target cluster submerged in a liquid medium, wherein, the cone target cluster comprises basic units with the same geometrical shape;

• the upper portion of the basic unit is a pyramid, and the lower portion is a corresponding prismatic base, vertexes of respective side surfaces of the pyramid converge at a perpendicular bisector of the prismatic base to form a cone vertex, and 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 of the container;
• it may be possible for 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 and open micropores are densely distributed inside each of the basic units of the cone target cluster.
