260. Repetitive Patient Exposure in Medical Imaging: Cumulative Dose, Risk, and Optimization Strategies

Abdelmoneim Sulieman (King Saud bin Abdulaziz University for Health Sciences)

26/06/2026, 09:00

Background: Repetitive patient exposure from CT, fluoroscopy, and interventional imaging is rising globally. Cumulative doses in heavily imaged cohorts can exceed 100 mSv (PET/CT mean ~79 mSv, range 6–399 mSv), raising stochastic cancer concerns despite clear diagnostic benefit.
Objective: To synthesise current evidence on cumulative patient exposure and integrate the authors' multi-year...

202. Peculiarities of X-Ray Transition Radiation Generation in a Periodic Teflon Radiators

Vardan Margaryan (Institute of Applied Problems of Physics NAS RA)

Radiation emitted by relativistic charged particles traversing natural or artificial periodic structures has been extensively studied in recent decades. It has been shown that, in such media, well-known processes – including parametric X-ray radiation, transition radiation (TR), and Cherenkov radiation – can exhibit interference effects that significantly modify their properties. In...

199. Prospects for an Intense Monochromatic X-Ray Source Based on Diffraction of Transition Radiation in in Crystals with a Temperature Gradient

Dr Vahan Kocharyan (Institute of Applied Problems of Physics of NAS RA)

Nowadays, X-ray radiation is widely used for imaging and probing the internal
structure of materials in advanced medical and biological applications owing to its high
penetration capability and its interactions with matter through absorption, diffraction,
reflection, and scattering. For many analytical techniques, monochromatic X-ray radiation is
of particular importance, as it enables the...

164. Feasibility of 3D-Printed Targets for Coherent Cherenkov Diffraction Radiation Generation

Dr Sergei Stuchebrov (National Research Tomsk Polytechnic University)

26/06/2026, 10:30

Polarization radiation is widely used for the diagnostic of charged particle beams due to its high sensitivity to various parameters, such as beam shape, bunch length, energy, and angular distribution. Special attention is given to coherent radiation, which occurs when the wavelength of the generated radiation is comparable to or exceeds the length of a single electron bunch. At most modern...

156. ON NONINVASIVE INFORMATION EXTRACTION FROM OBJECTS WITH VARIABLE ENTROPY

We have recently demonstrated both theoretically and experimentally [1,2] that the quantum vacuum, in the limit of statistical equilibrium in three-dimensional space, forms an energy lattice composed of massless spin-1 Bose particles, which we call hions. Our extensive experimental studies have shown that material objects, particularly those undergoing continuous active processes (such as...
