Abstract:
1. An ultrasonic diagnosis apparatus comprising: a data acquisition processor configured to acquire volume data, corresponding to a plurality of time phases, based on reception signals obtained by scanning a three-dimensional region including at least a part of a heart with ultrasonic waves; a setting processor configured to set a short axis plane for the volume data corresponding to at least one of the plurality of time phases; a tracking processor configured to set a plurality of three-dimensional positions for the volume data corresponding to a remaining time phase by a three-dimensional tracking of a plurality of positions on the short axis plane; a rotational angle computing processor configured to compute a regression plane of the plurality of positions for the remaining time phase, and a rotational angle of a region of interest, on the regression plane for the remaining time phase; a motion information acquisition processor configured to acquire tissue motion information concerning rotation by using the rotational angle; wherein the motion information acquisition processor is further configured to acquire the tissue motion information concerning a twist angle from a difference between two rotational angles in the circumferential direction by using the rotational angle computed on each of a plurality of curved surfaces in the circumferential direction which are segmented in a long-axis direction of the heart; and a display configured to display the tissue motion information concerning the rotation in a predetermined form and the twist angle in a predetermined form.
