Real analytic Radon transforms on rank one symmetric spaces
, 1993 Using microlocal techniques, we prove support theorems for Radon transforms with real analytic measures on horocycles in rank one symmetric spaces. We generalize Helgason’s support theorem to this case and prove a new local support theorem.

Artificial intelligence for adaptive neuromodulation in drug‐resistant epilepsy
Epilepsia, EarlyView.Abstract Drug‐resistant epilepsy (DRE) affects nearly one third of people with epilepsy and is associated with substantial cognitive, psychiatric, and mortality burdens. For patients who are not candidates for resection or laser interstitial thermal therapy, neuromodulation therapies such as vagus nerve stimulation, deep brain stimulation, and ...

A note on twisted discrete singular Radon transforms
, 2010 In this paper we consider three types of discrete operators stemming from singular Radon transforms. We first extend an $\ell^p$ result for translation invariant discrete singular Radon transforms to a class of twisted operators including an additional ...

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy
Epilepsia, EarlyView.Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.

A support theorem for Radon transforms on ℝn
, 1985 Let ƒ be a rapidly decreasing continuous function on ℝn and let f be its Radon transform. If f decreases fast enough and vanishes on a fairly large set, then it is proved that ƒ has compact support.

Fast Radon Transforms and Reconstruction Techniques in Seismology [Elektronisk resurs]
, 2016 The measurements conducted in tomography and seismology typically yield large multidimensional data sets. This in combination with the fact that the data may have an irregular structure makes it computationally prohibitive to use simple reconstruction ...
