Combining image based and inertial probe tracking |
| abstract |
An ultrasound imaging system with an inertial tracking sensor (20) rigidly fixed to an ultrasound probe (10). In a first embodiment, a real- time pose estimation unit (32) enhances image based tracking using the inertial data stream to calculate out-of-plane angles of rotation and determine an out-of-plane translation by iteratively selecting planes with the estimated out-of-plane rotations with varying out-of- plane offset, computing the differences between sub-plane distances computed by speckle analysis and the selected plane minimizing for the root mean square of the differences for all selected planes. In another embodiment, the real-time pose estimation unit enhances inertial tracking using the ultrasound image data stream to estimate an in-plane rotation angle; and substituting the in-plane rotation angle for an angle of rotation estimated using the inertial data stream. |
