3D ULTRASOUND REGISTRATION

摘要

Methods, apparatus and computer program code for registering a 3D ultrasound image with a 3D representation of a body part are described. The fit of the intensity values in the ultrasound image to the representation is optimising using at least one ultrasound scaling parameter as well as position and orientation parameters. The fit of the intensity can be optimised using at least two separate stages. The image and the representation can be converted into probabilistic images where the intensity of the pixels is proportional to the probability of that pixel containing a bone-to-soft tissue interface.
