Abstract
An acoustic probe includes a plurality of transducers that receives acoustic waves and a supporting body including a supporting portion having a symmetrical concave surface, such as a spherical cap surface, which supports the transducers in a spiral array. The supporting position R at which the supporting portion supports the transducers is given as R(r, θ, φ) [m, rad, rad] by a polar coordinate with respect to a center of the symmetrical concave surface by setting a sphere radius, a zenith angle, and an azimuth angle as 'r', 'θ', and “φ”, wherein the plurality of transducers is arrayed at a set azimuth angle spiral pitch in an azimuth angle direction and an axis direction spiral pitch set parallel to a central axis direction of the symmetrical concave surface, and wherein the azimuth angle spiral pitch is an angle acquired by dividing 2π by 1+golden number.
