21. Challenges in Fricke Dosimetry: Physics‑Informed Neural Networks for Correcting Diffusion and Auto‑Oxidation Artifacts

Mattia Romeo (University of Palermo)

Fricke gel (FG) dosimeters have attracted considerable interest in radiotherapy thanks to their capability to map three dimensional dose distributions (DDs). These systems exploit the radio induced oxidation of ferrous (Fe²⁺) to ferric (Fe³⁺) ions, using the concentration of Fe³⁺—detectable via magnetic resonance due to its paramagnetic properties—as a quantitative marker of absorbed dose....

The X-ray secondary sources driven by high-power lasers comprise unique features of micrometric source size and femtosecond pulse duration and are of high interest for time-resolved high-resolution X-ray imaging in a wide area of applications of physics, material science and biochemistry [1, 2]. The gas target requirements for optimal laser wakefield acceleration (LWFA) of electrons and...

The Imaging X-ray Polarimetry Explorer (IXPE) provides unique comprehension about polarized x-ray emissions from many astrophysical sources such as radio quiet and radio loud AGNs,galactic black hole binaries and neutron stars. Polarization maps in X-rays of pulsar wind nebulae and supernova remnants have been probed. IXPE has demonstrated the scientific potential of the techniques but...
