Abstract: Features are disclosed for rendering an image using a GPU and CPU based rendering pipeline. An imaging system may include a GPU and a CPU that each include a portion of an image renderer. A component of the GPU can process the set of image tiles to generate a texture with a wrapped tile coordinate. A component of the GPU can further store the image data as a level of a texture pyramid. As subsequent image data is received, a component of the GPU can access the texture pyramid to determine previously stored image tiles. A component of the GPU can use the previously stored image tiles in rendering the subsequent image data.

Abstract: A method of modifying a three dimensional (3D) volume visualization image of an anatomical structure in real time to separate desired portions thereof. The method includes providing a two dimensional (2D) image slice of a 3D volume visualization image of an anatomical structure, identifying portions of the anatomical structure of interest, and providing a prototype image of desired portions of the anatomical structure. The method then includes using an evolver to evolve parameters of an algorithm that employs a transfer function to map optical properties to intensity values coinciding with the portions of the anatomical structure of interest to generate an image that sufficiently matches the prototype image. If the parameters match the prototype image, the method then includes applying the transfer function to additional 2D image slices of the 3D volume visualization image to generate a modified 3D volume visualization image of the anatomical structure.
