Three-dimension velocity field reconstruction

The problem of inter-slice magnetic resonance (MR) image reconstruction is encountered imaging applications. In such scenarios, there is a need to opproximate not captured in contiguously acquired MR images due to hardware sampling limitations. In the context of velocity field reconstruction, these data are required,for visualiation and computational analyses of flow fields to be effective. To provide more velocity information, a method has been dcveloped for the reconstruction of flow fields on adaptive control grid interpolation (ACGI). In this study, data for reconstruction were acquired via MRI from in vitro models of surgically corrected pediatric vasculatures. Reconstructed velocity,fields showed strong qualitative agreement with those obtained via other acquisition techniques. Quantitatively, reconstruction was shown to produce data of comparable quality to accepted velocity (Iota acquisition methods. Results indicate that ACGI-based velocity field reconstruction is capable of producing suitable for a variety of applications demanding three-dimensional in vivo velocity data.
