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.

Method and apparatus for animate visualization of static 3-D data

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.

Method and apparatus for rendering an ultrasound image

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.

Methods and systems for removing occlusions in 3D ultrasound images

The invention relates to a method and a corresponding apparatus for multimodal visualization of volume data sets of an object, in particular a patient, comprising the following steps: acquiring a first volume data set of the object with a first imaging modality and a second volume data set of the object with a second imaging modality, said first and second volume data set each comprising a plurality of sample points and values (f,f) associated with said sample points, establishing a transfer function, said transfer function defining optical properties (c,&#x3b1;) of certain values (f,f) of said first and second volume data set, and visualizing the optical properties (c,&#x3b1;) of said certain values (f,f) of said first and second volume data set. In order to reduce the complexity of finding a good transfer function so that a transfer function can be defined by the user in an intuitive and familiar way, the transfer function is established by using information (I(f),I(f)) contained in a distribution (P(f),P(f)) of values (f,f) of said first and second volume data set.

Method and apparatus for multimodal visualization of volume data sets

A method and a corresponding apparatus for determining a position in an image, in particular a medical image enables a reliable determination of positions of interest in images of a variety of structures by displaying a volume rendering of image data acquired from an object, in particular a patient, pointing at a structure of interest displayed in the volume rendering of the image data, generating a viewing ray profile comprising information characterizing a ray running through said structure of interest, selecting a contextual profile from various contextual profiles, each of said contextual profiles comprising a representative ray profile representing a viewing ray profile of a structure, in particular an anatomical structure, and comprising profile information, and determining a position within said structure of interest based on said profile information of said selected contextual profile in the case that the representative ray profile of said selected contextual profile is matching with at least a part of said viewing ray profile.
