A new high definition voxel-based multi-planar reformatting method in 3-D ultrasound imaging

摘要

Multi-planar reformatting (MPR) in 3-D ultrasound imaging provides the viewer with planar cross-sectional images extracted from the 3-D data. To produce the MPR imaging from the acquired 3-D volume data, the 3-D scan conversion (SC), which transforms the acquired data in the 3-D polar coordinate system to the 3-D Cartesian coordinate system, is performed for display. Direct 3-D SC and separable 3-D SC method are most widely used approaches that they are followed by interpolation (e.g., trilinear or bilinear) using neighboring pixels. However, the direct 3-D SC and separable 3-D SC methods still suffer from blurring artifact; it may cause the deterioration of image quality. In this paper, we presents a new high definition MPR method using voxel based beamforming for reducing blurring artifacts.
