Abstract
A method and system for determination of geometric features in an object is provided. The method includes receiving at least one geometric feature response to an ultrasound beam incident on the object. The incident ultrasound beam is produced from one of a plurality of ultrasound transducers. Further, a volumetric representation of the object is generated based on a plurality of object parameters. The volumetric representation of the object and a plurality of transducer parameters are used to generate a predicted beam traversal path in the object. The predicted beam traversal path is utilized to generate a temporal map of predicted time of flight geometric feature response to the ultrasound beam. A position on the volumetric representation of the object is determined as the location of the geometric feature, when the received geometric feature response is equivalent to the predicted time of flight geometric feature response corresponding to the position.
