Kompilace 3D ultrazvukových dat snímaných metodou free-hand

Compilation of free-hand acquired 3D ultrasonic data

Paper in proceedings (conference paper)

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 visualisation 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. The objective is thus to replace the sensor with a technique for estimating the probe trajectory based on the B-scan images themselves. One such technique exists [1], based on a speckle decorrelation algorithm. In this paper we propose realisation of this method on image matching to accurate position using speckle correlation based algorithm, including the possible modification.
