Overview of interpolation methods for 3D freehand ultrasound

Overview of interpolation methods for 3D freehand ultrasound

Paper in proceedings (conference paper)

B-scans can be at any relative position and orientation. B-scan elements called pixels lie at irregular locations in the array of volume elements called voxels. This means the reconstruction problem can be classified as an unstructured or scattered data interpolation. There are number of different methods for 3-D ultrasound data reconstruction. Most of these methods are designed to minimize the time and memory. These methods take a few second and are preferred for visualization 3-D data sets immediately after acquisition. Details of the reconstruction are generally unpublished. Nevertheless, the methods that have been published can be classified into following categories: Voxel nearest neighbour interpolation, Pixels nearest neighbour interpolation and Distance-Weighted interpolation.
