Doppler ultrasound sonography is one of the widely used methods in clinical routine to assess blood flow dynamics and to measure blood velocities over time. It is, however, not trivial to recover at full 3D velocity information over time because Doppler US can only measure the projection of the true velocity along the beam direction.
Our work aims at reconstructing a 1) 3D velocity field and 2) a temporal flow profile based on arbitrarily sampled free-hand Doppler measurements without any gating or compounding.
