Influence of refractive index matching on the photon diffuse reflectance [PDF]
, 2002 Photon migration in a randomly inhomogeneous, highly scattering and absorbing semi-infinitemediumwith a plane boundary is considered by aMonte Carlo (MC) technique. The employed MC technique combines the statistical weight scheme and real photon paths

Combined proton-photon therapy for non-small cell lung cancer. [PDF]
Med Phys, 2022 PURPOSE Advanced non-small cell lung cancer (NSCLC) is still a challenging indication for conventional photon radiotherapy. Proton therapy has the potential to improve outcomes, but proton treatment slots remain a limited resource despite an ...

Photon acceleration in vacuum [PDF]
, 2006 A new process associated with the nonlinear optical properties of the electromagnetic vacuum, as predicted by quantum electrodynamics, is described. This can be called photon acceleration in vacuum, and corresponds to the frequency shift that takes place

Carbon Radiotheraphy For Head and Neck Cancer: Dosimetric Comparison with Photon Plans
Cumhuriyet Science Journal, 2022 Radiation therapy is one of the most widely used treatment methods for tumors. The therapeutic use of carbon ions is more advantageous than other radiotherapy techniquies especially photon-based irradiation due to its physical properties and ...

In vivo wireless photonic photodynamic therapy [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance The low penetration of light through tissue currently limits the therapeutic depth of photodynamic therapy (PDT) to less than a centimeter, even at near-infrared wavelengths. We report a wireless photonic approach to PDT in which miniaturized implantable devices deliver controlled doses of light by wireless powering ...

Proton versus photon radiation therapy: A clinical review
Frontiers in Oncology, 2023 While proton radiation therapy offers substantially better dose distribution characteristics than photon radiation therapy in certain clinical applications, data demonstrating a quantifiable clinical advantage is still needed for many treatment sites ...

Photon activation therapy and brachytherapy
Brachytherapy, 2009 In photon activation therapy (PAT), energy deposition at critical sites within a tumor can be increased by complexing the DNA with higher Z atoms, and provoking the emission of Auger electrons after inducing a photoelectric effect. This in vivo study evaluates the hypothesis using X-rays from palladium-103 seeds to excite the L-edge of platinum (Pt ...
