Three-dimensional ultrasound data display using multiple cut planes
First Claim
1. An imaging system comprising:
- a display subsystem for displaying images; and
a computer programmed to control said display subsystem to concurrently display in spaced relationship a three-dimensional projection image representing a projection of a data volume at a certain orientation, a first cut plane image representing a first planar cut through said data volume, a first graphic comprising a geometric representation of said data volume at said certain orientation and a second graphic comprising a geometric representation of said first cut plane, said second graphic having a positional relationship to said first graphic corresponding to the positional relationship of said first cut plane to said data volume;
and wherein said computer is further programmed to control said display subsystem to concurrently display a second cut plane image representing a second planar cut through said data volume and a third graphic comprising a geometric representation of said second cut plane, said third graphic having a positional relationship to said first graphic corresponding to the positional relationship of said second cut plane to said data volume, wherein said first and second cut planes are not parallel.

Abstract
A three-dimensional projection image representing a projection of a data volume at a predetermined orientation, three cut plane images representing respective mutually orthogonal planar cuts through the data volume, a graphical representation of the data volume at that orientation and graphical representations of the cut planes are displayed in spaced relationship. Each of the cut planes has a respective positional relationship to the data volume graphic that corresponds to the positional relationship of the respective cut plane to the data volume. The graphical representations are displayed in different colors. Any one of the four images can be active in the sense that images are reconstructed in real-time as a trackball is moved. Which of the four images is active is indicated by displaying the corresponding graphical representation in a color denoting the active state.
