The Transverse Oscillation method has shown its commercial feasibility, providing the user with 2D velocity information. Todays implementation on commercial ultrasound platforms only support linear array transducers and are limited in depth. Extending the implementation to a phased array transducer, vector velocity echocardiography will become possible. This paper describes the general modification...
We present a motion estimation algorithm for cardiac ultrasound images with transverse oscillations after base-band demodulation in the axial direction (B-mode TO). Our algorithm computes the motion by solving the optical-flow equation locally on a sliding spatial window. Conservation of the monogenic phase is assumed in lieu of the traditional pixel brightness. A local affine model accounts for typical...
