Heavy Ion Radiotherapy at the Lawrence Berkeley Laboratory

IEEE Transactions on Nuclear Science, 1983
Heavy ion radiotherapy potentially offers both dose localization and biologic advantages over conventional radiations in the treatment of cancer. Approximately 400 patients have been treated with either helium , carbon, neon, argon or silicon beams. Aspects of particle therapy are reviewed.

Recent Technology for Heavy Ion Radiotherapy

2018 22nd International Conference on Ion Implantation Technology (IIT), 2018
The technology of heavy ion radiotherapy (HI-RT) become established during over 40 years of experiences. The clinical results of HI-RT, obtained through scientific protocols and evaluations, have clearly demonstrated its advantages. At present, ten facilities are operating and eight are under commissioning or construction worldwide.

Influence of fragment reaction of relativistic heavy charged particles on heavy-ion radiotherapy

Physics in Medicine and Biology, 2003
The production of projectile fragments is one of the most important, but not yet perfectly understood, problems to be considered when planning for the utilization of high-energy heavy charged particles for radiotherapy. This paper reports our investigation of the fragments' fluence and linear energy transfer (LET) spectra produced from various incident

Treatment planning for heavy ion radiotherapy: clinical implementation and application

Physics in Medicine and Biology, 2001
The clinical implementation and application of a novel treatment planning system (TPS) for scanned ion beams is described, which is in clinical use for carbon ion treatments at the German heavy ion facility (GSI). All treatment plans are evaluated on the basis of biologically effective dose distributions.

[Heavy ion radiotherapy for lung cancer].

Nihon Geka Gakkai zasshi, 1997
In our institute, heavy ion medical accelerator in Chiba (HIMAC) completed to be constructed October, 1994. Next year, we started to treat head & neck cancer firstly as a pilot study using carbon beam. Following the observation on the expected reaction of skin and mucosa membrane, we opened the protocol for lung cancer entitled "A phase I/II and II ...

Optimization of Spiral-Wobbler System for Heavy-Ion Radiotherapy

Japanese Journal of Applied Physics, 2004
We propose an amplitude modulation wobbler-scatterer system, a so-called spiral-wobbler system, to produce a large irradiation field in a relatively short irradiation port for heavy-ion radiation therapy. The wobbler parameters, such as the wobbler-radius-modulation function, the wobbler radial frequency and the rotational frequency, are optimized ...

Heavy Ion Radiotherapy for Shallow-Seated Tumors at IMP

2009
By the end of 2008, clinical trials of heavy-ion radiotherapy for shallow-seated tumors have been carried out for seven times and 82 selected patients have been treated with 80-100 MeVu− 1 carbon ions supplied by the Heavy Ion Research Facility in Lanzhou (HIRFL) at the Institute of Modern Physics, Chinese Academy of Sciences (IMP-CAS) since November ...

Positron camera for range verification of heavy-ion radiotherapy

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003
Abstract A positron camera, consisting of a pair of Anger-type scintillation detectors, has been developed to verify ranges by using positron emitter beams. Each detector head is equipped with a NaI(Tl) crystal (diameter: 600 mm , thickness: 30 mm ) for high detection efficiency.

[Heavy charged particles radiotherapy--mainly carbon ion beams].

Gan to kagaku ryoho. Cancer & chemotherapy, 2004
Carbon ion beams have superior dose distribution allowing selective irradiation to the tumor while minimizing irradiation to the surrounding normal tissues. Furthermore, carbon ions produce an increased density of local energy deposition with high-energy transfer (LET) components, resulting in radiobiological advantages.
