Abstract:
1. A method for determining an imaging region in an ultrasonic imaging system, comprising: transmitting ultrasound energy into an insonified region in a current scan plane, thereby forming a transmitted sound field, and receiving ultrasound echo return signals from the insonified region; determining a range of a resultant image covered by the transmitted sound field based on energy lines of the transmitted sound field that have energy equal to a threshold; determining boundaries in a depth direction of the imaging region to be processed within said range according to characteristics of an imaging mode, said boundaries being determined as a function of the threshold and intensity values of echo signals from insonified points in the current scan plane, said boundaries thereby being variable according to each current scan plane; geometrically converting for display and displaying a representation of the intensity values originating only between the boundaries; and determining formulae F wherein, whether a point P(x, y) on the resultant image is located in the imaging region to be processed is determined according to the following conditions: if F
