Abstract: Rendering a time sequence of 2-D images includes obtaining ultrasound image data, applying time variant noise, and raytracing the ultrasound image data to render pixels of a 2-D image for each of a plurality of time steps.

Abstract: A method for rendering an image from ultrasound image data includes dividing the ultrasound image data into at least a first group of voxels and a second group of voxels, based on comparing voxel echo intensity to a threshold value. The method further includes processing the first group of voxels according to a first protocol and processing the second group of voxels according to a second protocol. The method further includes generating an image that includes both the first group of processed voxels and the second group of processed voxels to enhance realism of the rendered image.

Abstract: A method, system and medical imaging device include accessing a 3D medical imaging dataset and generating a volume-rendered image from the 3D medical imaging dataset. Generating the volume-rendered image includes calculating a shading for the volume-rendered image based on a first light source, a second light source, and a third light source. The second light source and the third light source are both positioned differently than the first light source. The method, system, and medical imaging device also include displaying the volume-rendered image.

Abstract: Methods and system for visualizing 3D ultrasound data are provided. One method includes obtaining image slices from a volumetric image data set and generating a ray profile using one or more rays through at least one of the image slices, wherein the one or more rays extend along a depth of the volumetric image data set. The method further includes identifying one or more seed points along the one or more rays and defining a clipping surface using the one or more seed points, wherein the clipping surface defines a rendering region within the volumetric image data set. The method also includes rendering a 3D image of the rendering region within the volumetric image data set.

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.
