Some uniqueness theorems for a conical Radon transform
Journal of Physics Communications, 2023 The conical Radon transform, which assigns to a given function f on ${{\mathbb{R}}}^{3}$ its integrals over conical surfaces, arises in several imaging techniques, e.g. in astronomy and homeland security, especially when the so-called Compton cameras are

Applied Sciences, 2018 Separation of downgoing and upgoing P-waves and S-waves in an offset 2D/3D vertical seismic profile (VSP) record is a basic step in VSP data processing. Radon transform and median filtering methods are commonly used to separate wavefields.

Reconstruction from Radon projections and orthogonal expansion on a ball
, 2007 The relation between Radon transform and orthogonal expansions of a function on the unit ball in $\RR^d$ is exploited. A compact formula for the partial sums of the expansion is given in terms of the Radon transform, which leads to algorithms for image ...

Rotation Invariant Automatic Infrared Target Recognition using G-Radon
MATEC Web of Conferences, 2016 In recent research, automatic target recognition (ATR) of infrared targets has been taking a lot of interest to the researchers. A rotation invariant method is useful in target recognition, classification and image analysis to reduce the number of ...

Discrete Applied Mathematics, 2001 The author studies properties of group codes, namely generalized weights and spectra of linear block codes over a finite field and their analogues for lattice sphere packings in Euclidean space. He obtains new results about linear codes, and generalizations of Siegel mean value and Minkowski-Hlawka theorems.

Extending the Support Theorem to Infinite Dimensions [PDF]
, 2009 The Radon transform is one of the most useful and applicable tools in functional analysis. First constructed by John Radon in 1917 it has now been adapted to several settings.

Metabolic and Microvascular Risk Factors Associated With Brain Health in Type 1 Diabetes
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT We examined relationships between metabolic factors, microvascular complications, and brain health in adults with type 1 diabetes. Fifty‐one adults were assessed for metabolic risk factors, microvascular complications, and cognitive function, with a subset completing brain MRI.
