Abstract
One of the main limitations of current 3D ultrasound (US) systems is that they cannot provide the real-time or interactive feedback that the sonographers and clinicians are accustomed to with conventional 2D clinical US machines. We have developed a low-cost high-performance interactive 3D US workstation that is suitable for use in a research and clinical environment.THis system employs a powerful programmable image processing board, the MediaStation 5000, to perform volume acquisition, reconstruction, and visualization. We have developed efficient reconstruction and visualization algorithms that allow our 3D US system to provide the same immediate feedback advantages as current 2D US technologies with the added advantage of presenting information in three dimensions. For acquired sequences of 512 X 512 US images, volumes can be reconstructed using a forward-mapped low-order interpolation scheme at 15 frame/s. A modified reconstruction algorithm that performs incremental reconstruction was developed for real-time volume visualization during acquisition. US volume visualization using shear-warp factorization and maximum intensity projection operates at 10 frame/s for 128 X 128 X 128 volumes.
