Digital twin volume registration for Voxel-based closed-loop machining systems
… presents a simple but novel technique for voxel volume model registration. This is done through the application of registering and machining near-net-shape structures and rough castings. Through the implementation of a Euclidean distance transform and variance calculation, an intensity-based …

Dynamic Multivariate Simplex Splines For Volume Representation And Modeling
<p>Volume representation and modeling of heterogeneous objects acquired from real world are very challenging research tasks and playing fundamental roles in many potential applications, e.g., volume reconstruction, volume simulation and volume registration. In order to accurately and efficiently …

Target localization in MRI-guided prostate biopsy
… Cancer Institute for over 6 years. A 3D-3D registration algorithm consists of an initial two-step rigid alignment followed by a B-spline deformable transform was developed to align the pre- and post-needle insertion images. A total of 90 biopsies from 24 patients were studied. The mean …

A Robust and Efficient Framework for Slice-to-Volume Reconstruction: Application to Fetal MRI
Volumetric reconstruction in presence of motion is a challenging problem in medical imaging. When imaging moving targets, many modalities are limited to fast 2D imaging techniques that provide cross-sectional snapshots (2D images) of the subject with an attempt to "freeze'' in-plane motion. …

Development of a 3D radial MR Imaging sequence to be used for (self) navigation during the scanning of the fetal brain in utero
… makes these sequences sensitive to signal misregistration and motion-corruption. Corruption of a single 2D slice renders it impossible to reconstruct 3D volumes from these slices without complex slice-to-volume registration. There is a need for motion-robust sequences that can produce …
