DEVELOPMENT OF A 3-DIMENSIONAL COLOR DOPPLER SYSTEM

An unprecedented assembly of a three-dimensional (3D) color Doppler sy stem was arranged for the purpose of producing and displaying precisel y calculated and recorded 3D color flow mapping images of fetal and um bilical vessels. Data accuracy and quality were enhanced by a computer controlled probe positioner. Scanning was across any of three perpend icular planes to collect serial slice images in any position and inter val width. The series of parallel images was digitized in a color imag ing processor by a 3D reconstruction program. Analyzed data were trans ferred to work stations for immediate processing into 3D form and disp lay. The resulting 3D display was a solid model image of umbilical ves sels which could be rotated in real time. In addition to the clear inf ormation about the vessel's structure, hemodynamics were apparent.
