1. A system for medical diagnostic ultrasound imaging, the system comprising:
- an ultrasound imaging system operable to generate data representing a body with an ultrasound transducer, the ultrasound imaging system comprising a three-dimensional image processor operable to render first and second three-dimensional representations as a function of the data, the first and second three-dimensional representations corresponding to first and second different viewing angles, respectively; and
a stereoscopic display operable to display the first and second three-dimensional representations;
wherein the first and second three-dimensional representations are positioned in first and second sub-fields of a data frame, wherein the ultrasound imaging system further comprises;
a synchronization circuit operable to increase a vertical synchronization rate or a horizontal synchronization rate associated with the data frame; and
a video processing unit operable to separate the first and second three-dimensional representations from the first and second sub-fields of the data frame and generate sequential display of the first and second three-dimensional representations as a function of the increased synchronization rate.
