Dosimetric impact of stopping power for human bone porosity with dual-energy computed tomography in scanned carbon-ion therapy treatment planning

Scientific Reports
Few reports have documented how the accuracy of stopping power ratio (SPR) prediction for porous bone tissue affects the dose distribution of scanned carbon-ion beam therapy.

Factors requiring adaptive re-planning in carbon ion radiotherapy for head and neck cancers

Frontiers in Oncology
BackgroundThe anatomical changes during carbon ion radiotherapy (CIRT) for head and neck cancers frequently require plan adaptations with adaptive re-planning. However, the details of the anatomical changes and their rates are not clear.

Heavy-ion reactions at the GSI Darmstadt

, 1998
In nucleus-nucleus collisions at bombarding energies on the order of 1 AGeV nuclear matter can be compressed to similar densities as encountered in stellar processes, i.e. to 2-3 times normal density.

Efficacy and safety of carbon-ion radiotherapy for large hepatocellular carcinoma (diameter ≥ 10 cm)

BMC Cancer
Background Large, unresectable hepatocellular carcinoma (HCC) remains incurable, and the risk of radiation-induced liver damage makes definitive radiotherapy challenging.

The role of quantum effects and nonequilibrium transport coefficients for relativistic heavy ion collisions [PDF]

, 2006
Stopping power and thermalization in relativistic heavy ion collisions is investigated employing the quantum molecular dynamics approach. For heavy systems stopping of the incoming nuclei is predicted, independent of the energy.

Depth-dose and fluence distributions when using heavy ion beams

, 1995
We have measured the depth-dose distributions for beams of "1"2C (270 and 330MeV/u), "1"8O (200,300 and 400 MeV/u) and "2"0Ne (670 MeV/u) delivered by the heavy-ion synchrotron SIS using water as a tissue-equivalent absorber.

Heavy-ion physics at LHC

Journal of Physics G: Nuclear and Particle Physics, 2004
Starting in 2007 the Large Hadron Collider (LHC) at CERN will collide proton beams at sqrt(s)=14 TeV and lead beams at sqrt(sNN) = 5.5 TeV. The experiments are presently under construction and a detailed physics programme is under preparation. I will review a few heavy-ion physics aspects for which LHC will be unique and will also discuss the detectors
