Abstract

The present disclosure describes a medical imaging and/or visualization system and method that provide a user interface enabling a user to visualize (e.g., via a volume rendering) a three dimensional (3D) dataset, manipulate the rendered volume to select a slice plane, and generate a diagnostic image at the selected slice plane, which is enhanced by depth colorized background information. The depth colorization of the background image is produced by blending, preferably based on the depth of structures in the volume, two differently colorized volume renderings, and then fusing the background image with a foreground diagnostic image to produce the enhanced diagnostic image.

Claims19

Dependent claims

A medical image data visualization system comprising:

an input device connected to a source of 3D medical imaging data;
an output device connectable to a display;
and
a processor connected to the input device and the output device and configured to:
receive from the input device a 3D dataset representative of a volume of imaged biological tissue;
crop the volume of the imaged biological tissue at a selected slice plane by removing the portion of the volume between the selected slice plane and a viewing plane;
generate a foreground image comprising a 2D image of bodily structures at the selected slice plane;
generate first and second color volume renderings of the cropped volume of the imaged biological tissue from a same viewing perspective, wherein the first and second color volume renderings are associated with respective first and second different color maps;
blend the first and second color volume renderings to produce a background image;
and
combine the foreground image and the background image to produce a composite medical image.

8 more elements

A method of visualizing 3D medical image data, the method comprising:

displaying a volume rendering of a 3D dataset representative of a volume of imaged biological tissue;
cropping the volume of the imaged biological tissue responsive to an indication of a selected slice plane by removing the portion of the volume between the selected slice plane and a viewing plane;
generating a foreground image comprising a 2D slice image at the selected slice plane;
generating a first color volume rendering of the cropped volume of the imaged biological tissue based on a first color map;
generating a second color volume rendering of the cropped volume of the imaged biological tissue based on a second different color map;
blending the first and second color volume renderings to produce a background image, wherein the blending is based at least in part on estimated depth of structures in the cropped volume of the imaged biological tissue;
and
combining the foreground image and the background image to produce a composite medical image,
wherein the first and second color volume renderings of the cropped volume of the imaged biological tissue are from a same viewing perspective.
