Review on heavy ion radiotherapy facilities and related ion sources (invited) [PDF]

Review of Scientific Instruments, 2010
Heavy ion radiotherapy awakens worldwide interest recently. The clinical results obtained by the Heavy Ion Medical Accelerator in Chiba at the National Institute of Radiological Sciences in Japan have clearly demonstrated the advantages of carbon ion radiotherapy. Presently, there are four facilities for heavy ion radiotherapy in operation, and several

Flourish of Proton and Carbon Ion Radiotherapy in China

Frontiers in Oncology, 2022
Proton and heavy ion therapy offer superior relative biological effectiveness (RBE) in the treatment of deep-seated tumors compared with conventional photon radiotherapy due to its Bragg-peak feature of energy deposition in organs. Many proton and carbon

Prompt gamma spectroscopy retrieval algorithm for element and density measurements accelerated by cloud computing

Frontiers in Physics, 2022
Prompt gamma ray in proton therapy is the product of a nuclear reaction between a proton and a target. The characteristic energies and intensities of prompt gamma lines can be used to determine the types of elements and their amounts in the target.

Carbon-ion Radiotherapy for Colorectal Cancer

Journal of the Anus, Rectum and Colon, 2021
Heavy-ion radiotherapy (RT) is a kind of particle RT, and carbon-ion beam constitutes the primary delivery method of heavy-ion RT. Unlike the conventional photon modalities, particle RT, in particular carbon-ion radiotherapy (CIRT), offers unique ...

The grid-dose-spreading algorithm for dose distribution calculation in heavy charged particle radiotherapy [PDF]

, 2007
A new variant of the pencil-beam (PB) algorithm for dose distribution calculation for radiotherapy with protons and heavier ions, the grid-dose spreading (GDS) algorithm, is proposed.

Results of heavy ion radiotherapy [PDF]

Radiation and Environmental Biophysics, 1995
The potential of heavy ion therapy for clinical use in cancer therapy stems from the biological parameters of heavy charged particles and their precise dose localization. Biologically, carbon, neon, and other heavy ion beams (up to about silicon) are clinically useful in overcoming the radioresistance of hypoxic tumors, thus increasing the biological ...

Towards Laser Driven Hadron Cancer Radiotherapy: A Review of Progress [PDF]

, 2014
It has been known for about sixty years that proton and heavy ion therapy is a very powerful radiation procedure for treating tumours. It has an innate ability to irradiate tumours with greater doses and spatial selectivity compared with electron and ...

Scintillating fiber devices for particle therapy applications [PDF]

, 2018
Particle Therapy (PT) is a radiation therapy technique in which solid tumors are treated with charged ions and exploits the achievable highly localized dose delivery, allowing to spare healthy tissues and organs at risk.

Measuring Leukocyte Adhesion to (Primary) Endothelial Cells after Photon and Charged Particle Exposure with a Dedicated Laminar Flow Chamber

Frontiers in Immunology, 2017
The vascular endothelium interacts with all types of blood cells and is a key modulator of local and systemic inflammatory processes, for example, in the adhesion of blood leukocytes to endothelial cells (EC) and the following extravasation into the ...
