Abstract
A 3-D ultrasound imaging system acquires partially complete image volumes interspersed with substantially complete image volumes. The partially complete image volumes contain speckle that is processed by a cross-correlation algorithm to track the movement of an ultrasound scanhead. By tracking the movement of the scanhead, the substantially complete image volumes can be properly registered with each other and combined to create a 3-D extended field of view image. The partially complete image volumes contain significantly less data than the substantially complete image volumes. Therefore, the partially complete image volumes can be acquired more quickly than the substantially complete image volumes to allow the scanhead to be scanned at a relatively fast speed.
