Abstract:
This paper provides a method of positioning the ultrasound probe in MR system. Machining 6 slots or cylinder perpendicular to the ultrasound probe surface on the edge of ultrasound probe as markers, 12 central cylinder ends are chosen as positioning points. By calculating these positioning points' coordinates in MR's coordinate system, the coordinate transformation between the ultrasound and MR coordinate system can be computed. Furthermore, by taking advantage of redundant information, calculating errors can be reduced and the precision can be improved.
