Ultrasound imaging method and ultrasound imaging system therefor

An ultrasound imaging method includes providing a digital representation of the shape of a surface or boundary of an anatomic region or organ; acquiring an ultrasound image by ultrasound scanning the anatomic region or organ; and combining the digital representation of the shape of the surface or boundary of the anatomic region or organ by registering the digital representation of the shape of the surface or boundary and the ultrasound image as a function of the difference in position of selected reference points on the digital representation of the surface or boundary and on the ultrasound image, the position of the reference points on the ultrasound image being determined by tracking the probe position at the reference points at the anatomic region or organ of a real body and in a spatial reference system, in which the anatomic region or the organ of the real body is placed.
