3D freehand ultrasound calibration accuracy

Paper in proceedings (conference paper)

In clinical applications 3D freehand ultrasound is finding its place and with higher fidelity of imaging is now partly applicable in common use. A positional sensor is attached to a conventional ultrasound probe, so that as B-scans are acquired they can be labeled with their relative positions and orientations. This allows 3D voxel array to be compounded from several B-scans. Such array can be visualized using plane slicing, volume rendering or surface rendering. A key requirement in freehand imaging is calibration; determining the position and orientation of the B-scan with respect to the position sensor.
