A Quality Control Assay to Access the HCl Molarity of Radionuclide Solutions

open access: yesChemosensors, 2016
Strontium-82 is produced by proton activation of a rubidium chloride target in an accelerator or cyclotron and purified by ion exchange chromatography. The Strontrium-82 is used in Cardigen generators to produce Rubidium-82 for cardiac imaging.

Radiobiology studies of gold nanoparticle‐enhanced radiosensitization in proton therapy

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Approximately 50%$\%$ of newly diagnosed cancer patients worldwide receive radiotherapy, most commonly with X‐rays. Proton therapy has emerged as a promising alternative, offering complementary advantages over conventional X‐rays due to its highly localized energy deposition at the Bragg peak, thereby reducing radiation exposure to ...

Characterization and calibration of the iQID digital autoradiography system for direct quantitative imaging of beta‐emitters in tissue samples

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Autoradiography provides microscale mapping of radionuclide distributions, offering a promising approach to complement nuclear medicine imaging for small‐scale radiopharmaceutical therapy (RPT) research. However, while quantitative protocols for α‐emitters are well‐established, comparable methods for β‐emitters, such as the widely ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Simulations of ion cyclotron emission from highly energetic fusion-born protons in aneutronic deuterium-helium-3 plasmas

open access: yesNuclear Fusion
Studies of future aneutronic fusion plasmas, such as those comprising deuterium and helium-3 (D– $^3\mathrm{He}$    $\rightarrow \mathrm{^4He}+p$ ), may not be able to exploit neutron-based diagnostics for direct measurement of fusion reactivity.

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Ray Tracing Method in a General Non‐Dipole Magnetic Field

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a new general mathematical formulation of the Eikonal equations for ray tracing, which can use any internal magnetic field model. The analytical and tractable expressions are conveniently based on a vector formalism, which is independent of any coordinate system.
