CLAIRE—Parallelized Diffeomorphic Image Registration for Large-Scale Biomedical Imaging Applications
Publikováno v:
Journal of Imaging, Vol 8, Iss 9, p 251 (2022)
We study the performance of CLAIRE—a diffeomorphic multi-node, multi-GPU image-registration algorithm and software—in large-scale biomedical imaging applications with billions of voxels. At such resolutions, most existing software packages for di

The discretization of certain integral equations, e.g., the first-kind Fredholm equation of Laplace's equation, leads to symmetric positive-definite linear systems, where the coefficient matrix is dense and often ill-conditioned. We introduce a new p

It is well-known that expanding glioblastomas typically induce significant deformations of the surrounding parenchyma (i.e., the so-called “mass effect”). In this study, we evaluate the performance of three mathematical models of tumor growth: 1)

We propose a method for extracting physics-based biomarkers from a single multiparametric Magnetic Resonance Imaging (mpMRI) scan bearing a glioma tumor. We account for mass effect, the deformation of brain parenchyma due to the growing tumor, which

Optimal control theory is branch of mathematics that aims to optimize a solution to a dynamical system. While the concept of using optimal control theory to improve treatment regimens in oncology is not novel, many of the early applications of this m

In this article, we study performance and energy saving benefits of hardware acceleration under different hardware configurations and usage scenarios for a state-of-the-art Fast Multipole Method (FMM), which is a popular N-body method. We use a dedic
