X-ray tool for 3D ultrasound
First Claim
1. A method for rendering an ultrasound volume, the method comprising:
- generating an image of an ultrasound volume, the image showing an outer surface of the volume image as opaque;
placing an internal image window at a position over the volume image, the internal image window being defined by a border and a transparency visualization parameter which causes the surface within the border to be displayed transparently so that an internal image of the internal structure of the volume is displayed in anatomical alignment with a fractional part of the volume over which the internal image window is placed; and
moving the internal image window with a user control to a new position over the volume image, wherein the fractional part within the border at the new position is replaced with an internal image of the volume in anatomical alignment with the new position of the internal image window,wherein the outer surface of the volume image outside of the border is displayed as opaque at both positions.

Abstract
A system and method is disclosed for rendering an ultrasound volume. An external image of an ultrasound volume is generated. A fractional part of the external image corresponds to a fractional portion of the ultrasound volume. A composite image of the ultrasound is generated using the external image, wherein the fractional part of the external image is replaced with an internal image of the ultrasound volume fractional portion. The internal image may be generated by changing a value of a visualization parameter used to generate the external image to a value more suitable for rendering an internal image. The ultrasound volume may include a organic structure, wherein the external image depicts an outer surface of the organic structure, and the internal image depicts a vascularity of the organic structure, such that the composite image simultaneously depicts both an outer surface and the vascularity of the organic structure.
