Medical diagnostic ultrasound system and method for mapping surface data for three dimensional imaging
First Claim
1. A medical diagnostic method for mapping data for three-dimensional imaging, the method comprising the acts of:
- (a) determining a boundary from a set of a first type of ultrasound data representing a three dimensional region; and
(b) rendering an image from a set of a second, different type of ultrasound data representing the three-dimensional region wherein the rendering is performed as a function of the boundary.

Abstract
A method and system for mapping surface data onto a geometrical representation of a structure for 3D imaging is provided. A boundary of a structure is determined from one type of data, such as Doppler energy data. Another type of data, such as B-mode data, representing the boundary or an area adjacent the boundary is extracted or identified. The B-mode data is then rendered as a function of the boundary, such as by texture mapping the B-mode data onto or adjacent the boundary. As the user examines the structure representation, the texture mapped data may provide texture details based on an optimally determined representation. The boundary may alternatively be used to select data for volume rendering.
