Viewing direction dependent acquisition or processing for 3D ultrasound imaging
First Claim
15. A method for acquiring ultrasound data in volume rendering, the method comprising:
- (a) determining a viewing direction relative to a 3D space; and
(b) setting a parameter for one of;
an acquisition, a beamforming, a coherent image forming, an image processing and combinations thereof as a function of the viewing direction.

Abstract
To improve real time 3D imaging performance, acquisition, beamforming, coherent image forming and/or image processing parameters are varied as a function of the viewing direction selected by the user. For example, the scan planes are oriented relative to the viewing direction. As a result rapid 3D rendering is provided without complex additional data interpolation or other 3D rendering processes. In another example, data along the lateral axis that is perpendicular to the viewing direction (i.e., display lateral axis) is acquired with parameters adapted to maximize field of view, detail and contrast resolution, while data along the lateral axis that is parallel to the viewing direction is acquired with compromised field of view, detail or contrast resolution. As a result, a high volume rate 3D imaging is achieved with 2D-equivalent detail resolution, contrast resolution and field of view along the display lateral axis.

17. A method for volume rendering with ultrasound data, the method comprising:
-
(a) determining a viewing direction relative to a 3D space; and
(b) performing 2D scans along planes substantially perpendicular to the viewing direction along at least one dimension;
(c) foreshortening 2D areas corresponding to the 2D scans as a function of depth along the viewing direction;
(d) combining the ultrasound data representing the foreshortened 2D areas; and
(e) generating a 3D representation from the combined ultrasound data. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 18, 19, 20, 21, 22, 23, 24, 25, 26)
