Abstract
Abstract An ultrasound imaging system incorporating the invention enables a user to select a pre-set anatomical view that is not available from standard ultrasound transducer imaging positions. The system includes a transducer which produces an ultrasound beam that acquires a 3-D set of echo signals. A processor enables the system user to be presented with a listing of pre-set anatomical views and is responsive to user selection of one of the pre-set views to control a converter within the system to derive from the 3-D set of echo signals, an image data set which, when displayed, presents the pre-set anatomical view selected by the user. In the preferred embodiment, at least some of the pre-set anatomical views are those that are not otherwise available from the standard transducer imaging positions.
