Future Radiation Therapy: Photons, Protons and Particles
Future Oncology, 2013Radiation therapy plays a critical role in the current management of cancer patients. The most common linear accelerator-based treatment device delivers photons of radiation. In an ever more precise fashion, state-of-the-art technology has recently allowed for both modulation of the radiation beam and imaging for this treatment delivery.

Recent Advances in Two-Photon Photodynamic Therapy
Anti-Cancer Agents in Medicinal Chemistry, 2008Photodynamic therapy (PDT) is a treatment for tumors and accepted in several countries in the world. Introduction of two-photon absortion (2PA) into PDT allows spatially selective treatment of cancers. Possibilities and limitations of the use of two-photon excitation in PDT are discussed, and many literatures in this area are reviewed.

Photon-limited Cherenkov imaging of radiation therapy dose
Optics Letters, 2023Cherenkov imaging is a unique verification tool that could provide both dosimetric and tissue functional information during radiation therapy. However, the number of interrogated Cherenkov photons in tissue is always limited and tangled with stray radiation photons, severely frustrating the measurement the signal-to-noise ratio (SNR).

Robust mixed electron–photon radiation therapy optimization
Medical Physics, 2019PurposeMixed beam electron–photon radiation therapy (MBRT) is an emerging technique that has the potential to reduce dose to normal tissue while improving target coverage for cancer sites with superficial tumors. Advances in optimization algorithms and robotic linear accelerators have made the creation and delivery of complex MBRT plans realistic ...

Collimator scatter in photon therapy beams
Medical Physics, 1995A model for collimator photon scatter calculations is presented. The scatter from a collimating block is separated into two categories, one being the scatter released from photons entering the block through the surface facing the source, and one from photons striking the block tangentially through the side tangential to the beam.

It is suggested here that significant advantages should accrue from the use of 40 keV photons from implanted sources of 145Sm. These energies should stimulate Auger electron cascades from IdUrd, as well as produce non-repairable damage from radiosensitization.

Photonic metallic nanostructures in photodynamic therapy
SPIE Proceedings, 2009ABSTRACT Plasmons are resonant modes that involve the interaction between free charges and light. Nanoparticle-based photonic explorers have been developed for photodynamic therapy (PDT). PDT has been widely used in both oncological (e.g., tumors) and nononcological (e.g., age-related macular degeneration, localized infection, and nonmalignant skin ...

Two-photon photodynamic therapy with curcumin nanocomposite
Colloids and Surfaces B: BiointerfacesTwo-photon photodynamic therapy (TP-PDT) offers an innovative approach to cancer treatment that utilizes near-infrared light to activate photosensitizers and generate reactive oxygen species (ROS) for targeted cancer cell elimination. TiO2-CUR-Sofast (TCS), which uses TiO2 nanoparticles and Sofast cationic polymer to modify curcumin (CUR), has ...

Applied photonic therapy in veterinary medicine
SPIE Proceedings, 2005There can be no question that specific systemic physiological results occur, when red light (660nm) is applied to the skin, it is now more a question of detailed mechanisms. Before gathering statistically signifcant clinical trial data, it is important to first enumerate the type of results observed in practice.
