Complex-Valued Multiresolution Volume Rendering in 3D Echocardiography

Complex-Valued Multiresolution Volume Rendering in 3D Echocardiography

Paper in proceedings (conference paper)

A number of techniques have been proposed for rendering volumetric data sets. A modern approach lies in the use of a hierarchical description of images that are decomposed into a sequence of multiscale representations. Discrete-time wavelet transform (DWT) is often used for the decomposition. This approach is similar to that used in computer graphics where scenes are utilized in structures called octrees. A ray-casting based method using complex-valued DWT has been proposed to serve as a rendering technique for visualization of medical images from various modalities such as CT and MR.
