USCT Sound-Speed Reconstruction

USCT Sound-Speed Reconstruction

Software

The software is aimed at reconstruction of sound-speed volumes from ultrasound radiofrequency signals acquired using a 3D ultrasound computer tomography (USCT) system. In contrast to 2D USCT systems, a 3D system can provide an isotropic spatial resolution in the x- y- and z-directions in reconstructed 3D images of ultrasound parameters. Several challenges are however to be addressed for 3D systems, namely a sparse transducer distribution, low signal-to-noise ratio and higher computational complexity. These issues are addressed in terms of sound-speed image reconstruction, using edge-preserving regularized algebraic reconstruction in combination with synthetic aperture focusing.
