Abstract
An ultrasonic imaging apparatus for obtaining a two-dimensional distribution of a predetermined characteristic parameter of a medium of the ultrasound at various points in a plane. The apparatus contains a unit for designating a region of interest in said plane, and a unit for obtaining and indicating statistical information on a dispersing characteristic of said predetermined characteristic parameter of the medium at the various points in the region of interest of said plane. In addition, the apparatus contains a unit for obtaining and indicating a recent history of the dispersing characteristics during the operation of obtaining the two-dimensional distributions which are most recently carried out. Further, the apparatus contains a unit for obtaining and indicating the plane for which the minimum standard deviation is obtained, and a unit for indicating the two-dimensional distribution for the plane.
