First Claim
Patent Images
1. A method of volume-rendering 3D medical imaging data comprising:
- generating a volume-rendered image from a 3D dataset acquired with a medical imaging device, wherein the volume-rendered image is shaded from a light direction;
displaying the volume-rendered image;
displaying a model of a solid at the same time as the volume-rendered image; and
displaying a light direction indicator with respect to the model of the solid, wherein the position of the light direction indicator with respect to the model of the solid corresponds to the light direction used for shading the volume-rendered image.

Abstract
A method and system for volume-rendering. The method and system include generating a volume-rendered image that is shaded from a light direction, displaying the volume-rendered image, displaying a model of a solid at the same time as the volume-rendered image, and displaying a light direction indicator with respect to the model of the solid, wherein the position of the light direction indicator corresponds to the light direction used for shading the volume-rendered image.

1. A method of volume-rendering 3D medical imaging data comprising:
-
generating a volume-rendered image from a 3D dataset acquired with a medical imaging device, wherein the volume-rendered image is shaded from a light direction; displaying the volume-rendered image; displaying a model of a solid at the same time as the volume-rendered image; and displaying a light direction indicator with respect to the model of the solid, wherein the position of the light direction indicator with respect to the model of the solid corresponds to the light direction used for shading the volume-rendered image. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of volume-rendering 3D medical imaging data comprising:
-
displaying a volume-rendered image that is shaded from a first light direction, wherein the volume-rendered image is based on a 3D dataset acquired from a medical imaging device; displaying a model of a solid at the same time as said displaying the volume-rendered image; displaying a light source indicator at a first position with respect to the model of the solid, wherein the first position of the light source indicator corresponds to the first light direction used to shade the volume-rendered image; moving with a user interface the light source indicator to a second position with respect to the model of the solid; and automatically updating the shading on the volume-rendered image to correspond with the second position of the light source indicator with respect to the model of the solid. - View Dependent Claims (24, 25, 27, 28)

26. The method of 23, wherein the model of the solid comprises a representation of a polygonal model and is transparent or semi-transparent, wherein the model of the solid is a different shape than the volume-rendered image, and wherein displaying the model of the solid at the same time as displaying the volume-rendered image includes displaying the model of the solid at the same time as but separate from the volume-rendered image on a display device.

29. A system for interacting with a 3D dataset comprising:
-
a display device; a memory; a user input; and a processor communicatively connected to the display device, the memory and the user input, wherein the processor is configured to; access a 3D dataset from the memory, where the 3D dataset was acquired with a medical imaging device; generate a volume-rendered image from the 3D dataset that is shaded from a light direction; display the volume-rendered image on the display device; display a model of a solid at the same time as the volume-rendered image; and display a light source indicator at a position with respect to the model of the solid to indicate the light direction used for shading the volume-rendered image. - View Dependent Claims (30, 31, 32, 33)
