Abstract:
1. A system for three dimensional navigation with medical diagnostic ultrasound imaging, the system comprising: a handheld volume object; a medical diagnostic ultrasound system configured to generate a three dimensional representation of an ultrasonically scanned region; and a sensor on the handheld volume object, the medical diagnostic ultrasound system or both the handheld volume object and the medical diagnostic ultrasound system, the sensor configured to determine an orientation in three-dimensions of the handheld volume object, the handheld volume object being handheld during operation of the sensor; wherein the medical diagnostic ultrasound system generates the three dimensional representation as a function of a viewing angle responsive to the orientation, the volume object representing the scanned region such that the viewing angle is determined as if a user is looking at the volume object as the scanned region where changes in the orientation of the volume object rotate the scanned region, causing rotation of the three dimensional representation in direct correspondence.
