dcterms:description
In the free-hand 3D ultrasonography, the position of the us. probe of a 2D ultrasound scanner is sensed by a special positioning subsystem so that the us. data are accompanied by the positional data. The resulting 3D data should permit flexible visualization and more accurate volume measurements than can be achieved using isolated 2D B-scans; however, the use of the position sensor may be inconvenient for the clinician and, moreover, the main disadvantage is that these position sensors are not accurate enough and calibration of the measuring equipment may be too complicated. The objective of the presented work is thus to replace the positioning sensor with a technique to estimate the probe trajectory based on the B-scan images themselves. Some publications on such techniques exist, based on speckle correlation analysis. In this paper, we propose a method of a different kind expected to enable accurate positioning using image-data registering based algorithm, including possible modifications.
