Three-dimensional velocity field reconstruction.
The problem of inter-slice magnetic resonance (MR) image reconstruction is encountered often in medical imaging applications, in such scenarios, there is a need to approximate information not captured in contiguously acquired MR images due to hardware sampling limitations. In the context of velocity field reconstruction, these data are required for visualization and computational analyses of fl...
متن کاملBayesian Stochastic Mesh Optimisation for 3D Reconstruction
We describe a mesh based approach to the problem of structure from motion. The input to the algorithm is a small set of images, sparse noisy feature correspondences (such as those provided by a Harris corner detector and cross correlation) and the camera geometry plus calibration. The output is a 3D mesh, that when projected onto each view, is visually consistent with the images. There are two ...

متن کامل3D Velocity Field and Flow Profile Reconstruction from Arbitrarily Sampled Doppler Ultrasound Data
With the need for adequate analysis of blood flow dynamics, different maging modalities have been developed to measure varying blood velocities over time. Due to its numerous advantages, Doppler ultrasound sonography remains one of the most widely used techniques in clinical routine, but requires additional preprocessing to recover 3D velocity information. Despite great progress in the last yea...
متن کاملImproving 3D MR Velocity-Vector Field Mapping by Divergence-Free Image Reconstruction
Introduction Phase-contrast magnetic resonance imaging (PC-MRI) provides time-resolved 3D information of velocity fields of flowing blood in vessels. It has however been noted that system imperfections including eddy current related phase offsets, sample noise, displacement and partial volume effects can compromise the accuracy of velocity data derived from phase-contrast measurements [1]. If o...
