3D Echocardiogram Reconstruction Employing a Flip Directional Texture Pyramid

Three dimensional (3D) echocardiogram enables cardiologists to visualize suspicious cardiac structures in detail. In recent years, this three-dimensional carries important clinical value virtual surgical simulation. However, 3D involves a trade-off difficulty between accuracy and efficient computation diagnosis. This paper presents novel Flip Directional Volume Reconstruction (FD-3DVR) method for the reconstruction of images. The proposed consists two main steps: multiplanar volumetric imaging volume reconstruction. creation imaging, two-dimensional (2D) image pixels are mapped into voxels grid. As obtained slices discontinuous, there some missing data. To restore structural textural information ultrasound volume, creates pyramid parallel with flip directional texture pyramid. Initially, nearest neighbors identified by ANN (Approximate Nearest Neighbor) patch matching method. Furthermore, is aggregated distance find out most similar neighbors. step, from different angle directions can reconstruct well desired accuracy. Compared existing methods, provides superior performance mean peak signal-to-noise ratio (40.538 I 39.626 II). Experimental results performed on datasets demonstrate efficiency
