摘要：
In this work a multi-rate higher order singular value decomposition (MRHOSVD) framework for enhanced non-contrast ultrasound Doppler imaging is proposed. Our method is based on Tucker decomposition of mult-idimensional plane wave ultrasound echo data at multiple temporal resolutions simultaneously. We present simulation and in vivo results where the new method outperforms classic singular value clutter filtering in separation of blood activities from tissue motions with significant bandwidth overlap.
