Methodology paper: a novel phantom setup for commissioning of scanned ion beam delivery and TPS

Radiation Oncology, 2019
Background Commissioning of treatment planning systems (TPS) and beam delivery for scanned light ion beams is an important quality assurance task. This requires measurement of large sets of high quality dosimetric data in anthropomorphic phantoms to ...

Effects of curved superconducting magnets on beam stability in a compact ion therapy synchrotron

Physical Review Accelerators and Beams
Superconducting, curved magnets can reduce accelerator footprints by producing strong fields (>3  T) and reducing the total number of magnets through their capability for combined-function multipolar fields, making them an attractive choice for ...

Dose and linear energy transfer distributions of primary and secondary particles in carbon ion radiation therapy: A Monte Carlo simulation study in water

Journal of Medical Physics, 2015
The factors influencing carbon ion therapy can be predicted from accurate knowledge about the production of secondary particles from the interaction of carbon ions in water/tissue-like materials, and subsequently the interaction of the secondary ...

Recurrent Axis Chordoma after Carbon ion Therapy Necessitating Reconstructive Surgery with Osteocutaneous Radial Forearm Free Flap: A Case Report

Journal of Reconstructive Microsurgery Open
Chordomas originate from remnant tissue of the notochord during embryonic development, with a relatively low incidence rate. Furthermore, chordomas, being resistant to radiotherapy, are primarily treated by resection; however, in some cases, particularly

Radioactive ion beam range adaptation in mouse tumors using in-beam PET

Communications Medicine
Background Treatment adaptation is particularly critical in particle therapy, where even small range deviations can compromise target coverage or lead to unintended dose delivered to surrounding healthy tissues. In-beam positron emission tomography (PET)
