"In free-hand 3D ultrasound, a position sensor is attached to the probe of a 2D ultrasound scanner. The resulting 3D data should permit flexible visualization and more accurate volume measurement than can be achieved using 2D B-scans alone; however the use of the position sensor can be inconvenient for the clinician but the main disadvantage is that these position sensors are not accurate enough and calibration of this is too complicated. The objective is thus to replace the sensor with a technique for estimating the probe trajectory based on the B-scan images themselves. Some publications on such techniques exist, based on a speckle correlation algorithm. In this paper we propose a method of this kind to accurate positioning using speckle correlation based algorithm, including possible modification." . . . . "573078" . . .
