Abstract
A 3D field of view ultrasound image volume is derived from correlated frames of ultrasound image data. An operator manually translates an ultrasound probe across a patient target area. Frames of sensed echo signals are processed to detect probe motion using beam data registration and correlation techniques. Motion is detected by correlating the frames for probe translation among as many as 6 degrees of freedom. Image registration then is performed for correlated portions to accumulate a large ultrasound image. Such image encompasses an area larger than a single field of view image frame for the given manually-scanned transducer probe.
