Free-hand 3D Ultrasound Imaging Software Package Ultra3D

A software package, Ultra3D, for ultrasound image processing and 3D visualization has been developed. In particular, it has been successfully integrated with a miniaturized Terason SmartProbeTM which is currently the only commercial ultrasound unit that is based on a PC. The software functions in Ultra3D have been tested using the SmartProbeTM, as well as other ultrasound units, mostly for fetal imaging. Fast 3D re-construction and revealing 3D images have demonstrated the usefulness of the software in achieving 3D ultrasound imaging on a portable/wearable ultrasound system. Future research is needed to develop the necessary hardware and improve the system's operations under a more hostile environment.
