Development of a three-dimensional color Doppler system.
An unprecedented assembly of a three-dimensional (3D) color Doppler system was arranged for the purpose of producing and displaying precisely calculated and recorded 3D color flow mapping images of fetal and umbilical vessels. Data accuracy and quality were enhanced by a computer controlled probe positioner. Scanning was across any of three perpendicular planes to collect serial slice images in any position and interval width. The series of parallel images was digitized in a color imaging processor by a 3D reconstruction program. Analyzed data were transferred to work stations for immediate processing into 3D form and display. The resulting 3D display was a solid model image of umbilical vessels which could be rotated in real time. In addition to the clear information about the vessel's structure, hemodynamics were apparent.
