Patent Images
1. A method for conveying spatial relationships in three-dimensional medical imaging, the method comprising:
- displaying a first three-dimensional representation of a first diagnostic view of at least a portion of the patient, the first three-dimensional representation being at a first viewing angle;
receiving an indication of a second diagnostic view of the portion;
animating a transition from the first diagnostic view to the second diagnostic view, the transition comprising a plurality of intermediary three-dimensional representations of the portion, each of the intermediary three-dimensional representations of the portion corresponding to different intermediary viewing angles; and
displaying a second three-dimensional representation of the second diagnostic view of the portion after the transition, the second three-dimensional representation being at a second viewing angle different than the first viewing angle, the different intermediary viewing angles different than the first and second viewing angles;
wherein displaying the first three-dimensional representation of the first diagnostic view comprises displaying with a first clipping plane for a first standard two-dimensional representation, wherein displaying the second three-dimensional representation of the second diagnostic view comprises displaying with a second clipping plane for a second standard two-dimensional representation, and wherein animating comprises removing the first clipping plane and adding the second clipping plane to a volume used for rendering the first and second three-dimensional representations.

Abstract
Spatial relationships are conveyed in three-dimensional ultrasound imaging. To transition a volume rendering from one view to another view, the transition is animated, showing rotation. For example, the user examines one diagnostic view, but decides to examine another diagnostic view. Upon selection of the other diagnostic view, the volume rendered image appears to rotate. The rotation from one view to another shows the spatial relationship between the views. The user may then examine the static volume rendering at the desired view with an appreciation of the relationship with the previously examined static view.

12. A system for conveying spatial relationships in three-dimensional medical imaging, the system comprising:
-
a memory operable to store data representing a volume of a patient; a processor operable to generate a plurality of three-dimensional representations of the volume from the data, each of the three-dimensional representations having a different viewing angle relative to the volume; a timer operable to cause static display of an initial three-dimensional representation of the plurality for a first period and a final three-dimensional representation of the plurality for a second period, and operable to cause display of a sequence of three-dimensional representations of the plurality between the initial and final three-dimensional representations, each of the three-dimensional representations of the sequence being displayed for a time less than the first and second periods; and a display operable to display the initial three-dimensional representation, the sequence of three-dimensional representations, and the final three-dimensional representation. wherein the processor is configured to display the initial three-dimensional representation with a first clipping plane for a first standard two-dimensional representation, to display the final three-dimensional representation with a second clipping plane for a second standard two-dimensional representation, and to display the sequence as removing the first clipping plane and adding the second clipping plane to a volume used for rendering the initial and final three-dimensional representations. - View Dependent Claims (13, 14)
