Two-Photon Photodynamic Therapy
Journal of Clinical Laser Medicine & Surgery, 1997We demonstrate the use of infrared excitation in conjunction with an efficient two-photon absorbing dye and a photosensitizer in photodynamic therapy.An efficient two-photon absorbing dye is excited by short infrared (800 nm) laser pulses, which transfer its energy to the photosensitizer and the photosensitizer, in turn, generates the singlet oxygen.A ...

Biological Considerations When Comparing Proton Therapy With Photon Therapy
Seminars in Radiation Oncology, 2013Owing to the limited availability of data on the outcome of proton therapy, treatments are generally optimized based on broadly available data on photon-based treatments. However, the microscopic pattern of energy deposition of protons differs from that of photons, leading to a different biological effect.

Regenerative photonic therapy: Review
AIP Conference Proceedings, 2012After four decades of research of photobiomodulation phenomena in mammals in vitro and in vivo, a solid foundation is created for the use of photobiomodulation in regenerative medicine. Significant accomplishments are achieved in animal models that demonstrate opportunities for photo-regeneration of injured or pathological tissues: skin, muscles and ...

Exit dose studies in megavoltage photon therapy
The British Journal of Radiology, 1983A coin-shaped ionisation chamber, orientated with its thin window facing away from the radiation source, was used to investigate the dose perturbations caused by the absence of back-scattering material near the exit surface of solid phantoms. Cobalt 60 and 4, 8 and 16 MV X-ray beams were used in the study. With no scattering material beyond the chamber

Molecular photosensitisers for two-photon photodynamic therapy
Chemical Communications, 2017With the recent development of clinical two-photon microscopes or endoscopes, new photosensitisers for two-photon photodynamic therapy are the subject of increasing interest. Herein, we review the advances within the ten last years of molecular two-photon photosensitisers.

Motion in radiotherapy: photon therapy
Physics in Medicine and Biology, 2012This review considers the management of motion in photon radiation therapy. An overview is given of magnitudes and variability of motion of various structures and organs, and how the motion affects images by producing artifacts and blurring. Imaging of motion is described, including 4DCT and 4DPET.

Photon and photon–neutron experimental dosimetry in Grid therapy with 18 MV photon beams
Journal of Radiotherapy in Practice, 2020AbstractPropose:Spatially fractionated Grid radiation therapy (SFGRT) in an effective technique for bulky and radio-sensitive tumours. SFGRT using a constructed block has been used to evaluate the photon and photo-neutron (PN) dose measurement in 18-MV photon beam energy.Methods and materials:A mounted Grid block on to a Varian Clinac 2100c linear ...
