摘要： Disclosed is a phase unwrapping technique based on the solution of the Poisson equation. The problem of phase unwrapping in the continuous domain is formulated using an optimization approach where a cost functional is minimized. The minimizer is shown to be a solution of the Poisson equation with an appropriate boundary condition; the choice of the boundary condition depends on the particular application. The solution to the Poisson equation, i.e., the phase that minimizes the cost functional is referred to as the least squares phase. The least squares phase has thereby been unwrapped but, in general, will differ from the absolute phase due to noise. Using the least squares phase, the absolute phase is finally determined with an operator that maps the least squares phase to the absolute phase so that the computed absolute phase and the measured phase differ by multiples of 2.pi..

摘要： A method and apparatus to reduce the noise in three-dimensional phase contrast magnetic resonance velocity measurements exploits the property that blood is incompressible and therefore the velocity field describing its flow must be divergence-free. The divergence-free condition can be incorporated by the projection operation on Hilbert space where the velocity measurements are projected onto the space of divergence-free velocity fields. The reduction of noise is achieved since the projection operation eliminates the noise component that is not divergence-free. Higher quality angiograms are produced due to the noise reduction in the velocity measurement signals.

摘要： Several algorithms are presented for determining the trajectory of a particle in motion given cine phase contrast (PC) velocity field data. The PC velocity field is usually measured in a fixed frame of reference (spatial coordinates) and must be transformed to the velocity in material coordinates, i.e., the velocity experienced by individual points in the medium. The material velocity field can then be integrated to yield the trajectory of a particular point. Therefore, to determine the trajectory of a particular point, the given spatial velocity field must be transformed to the material velocity field. While there exists a mathematical relationship that maps velocity fields in spatial coordinates to material coordinates, this mapping can be applied only if particle trajectories are known. Although there appears to be a dilemma here, through an optimization technique, we have devised an iterative procedure to determine the optimal trajectory in the sense to be defined.
